DETECTION AND CONFIRMATION OF FRESHWATER BLENNY Salaria fluviatilis (ACTINOPTERYGII: BLENNIDAE) IN BOSNIA AND HERZEGOVINA

Salaria fluviatilis je slatkovodna vrsta ribe čiji se raspon distribucije proteže na pritoke duž Sredozemnog i Crnog mora. Smatra se ugroženom u nekoliko europskih mediteranskih zemalja. Iako je prethodno spomenuta na popisima slatkovodnih vrsta riba, njezino prisustvo zapravo nikada prije nije potvrđeno u Bosni i Hercegovini. Slijedom toga, došlo je do sumnje u njezinu distribuciju u tom području. Uzorak riječne babice dobiven je iz donjeg dijela rijeke Neretve (sliv Jadranskog mora) u Bosni i Hercegovini u svibnju 2020. godine, što predstavlja prvi pouzdan zapis o ovoj vrsti. S obzirom na to da ovaj zapis potvrđuje starija izvješća, iako ranija istraživanja nisu uspjela locirati ovu vrstu. Poznavanje sastava ribljih vrsta u riječnim slivovima i ažuriranje njihovog popisa jedan je od važnih zahtjeva za upravljanje biološkom raznolikošću svake zemlje, kao i vodenim i ribljim resursima.Distributional range of freshwater blenny Salaria fluviatilis extends to the tributaries along the Mediterranean and Black seas. It is considered endangered in several Mediterranean European countries. Although previously mentioned in the lists of freshwater fish species, its presence has never before been confirmed in Bosnia and Herzegovina. Consequently, this has led to doubts about its distribution there. A sample specimen of freshwater blenny was obtained from the lower Neretva River (Adriatic Sea watershed) in Bosnia and Herzegovina in May 2020, representing the first reliable record of this species. Considering that this record confirms older reports, however, it seems that earlier surveys have failed to locate the fish. Knowledge of the composition of fish species in river basins and updating their list are among the important requirements for managing the biodiversity of each country, as well as water and fish resources

ZABILJEŠKA O NALAZU RIBE Symphodus roissali, RISSO 1810 (PISCES: LABRIDAE) BEZ REPA U SJEVERNOM JADRANU

On 08th August 2006 an tailless adult of five–spotted wrasse, Symphodus roissali (RISSO, 1810), were caught in the Cesarica cove (Northern Adriatic Sea). A possible reasons and causes for such phenomena are argued.Na području uvale Cesarica u sjevernom Jadranu 8. kolovoza 2006. ulovljen je odrasli primjerak ribe kosirica ili kraška (Symphodus roissali, RISSO, 1810) (Pisces: Labridae) bez repa. U radu se raspravlja o mogućim razlozima i posljedicama ovakve pojave

Unusual findings of softmouth trout Salmo obtusirostris (Actinopteri: Salmonidae) in the marine environment along the middle Eastern Adriatic coast as a consequence of extreme weather events

The discovery of individuals of softmouth trout Salmo obtusirostris in the marine environment has been recorded several times in the period from 2015 to the present day in the wider area of the Neretva River delta and southern Adriatic coast. Although this phenomenon appears to be happening more frequently along the Adriatic coast, scientific reports regarding family Salmonidae species found in the marine environment are still very rare in the eastern Adriatic, especially for the softmouth trout. The findings reported here represent the first marine records of this endemic freshwater species. An increasing frequency of these findings may indicate that a higher number of individuals are ending up in the coastal environment during heavy storm events or other unusual hydrologic occurrence. Extreme weather conditions have become more frequent in recent years, mainly as a result of climate change and have led to unexpected phenomena and impacts on nature. The long-term effects on fish and community structure of rivers flowing into the sea require further research, as these weather-induced situations can be expected to become more common. Further investigation into the physiological costs and population consequences of these unusual ecological findings is warranted

Das Potential von Tauchklubs bei der Verringerung von Abfall im Meer, der jetzige Zustand und die Perspektive in Kroatien

Morski otpad je veliki globalni ekološki problem današnjice uglavnom kao posljedica sve veće upotrebe plastike i neodgovarajućeg gospodarenja otpadom na kopnu. Prilikom dospijevanja u more većina otpada potone na dno u priobalnim područjima gdje se može godinama nakupljati. Otpad s morskog dna u plitkom priobalju može se jednostavno uklanjati organiziranjem ronilačkih ekoloških akcija. Ronilački klubovi imaju veliki potencijal u takvim akcijama čime se mogu ukloniti značajne količine otpada, međutim one se provode bez usklađene metodologije i koordinacije. Na taj način ostaju nam nepoznati podaci o područjima, količinama i sastavu prikupljenog otpada, koji inače imaju važnost za razvoj strategija za smanjivanje morskog otpada. Razvoj učinkovitih mjera za smanjivanje morskog otpada nužan za očuvanje biološke i gospodarske kvalitete morskog i priobalnog okoliša. U ovom je radu predstavljen potencijal ronilačkih akcija čišćenja plitkog podmorja u smanjivanju količina morskog otpada u Hrvatskoj. Posebno je istaknuta potreba za suradnjom ronilačkih klubova i znanstvenih institucija u cilju dobivanja što kvalitetnijih podataka o prikupljenom morskom otpadu, te važnosti provođenja usklađenog načina prikupljanja podataka čime se može značajno doprinijeti razvijanju spoznaja o sadašnjoj situaciji i trendovima te donošenju odgovarajućih preporuka i zakonodavnih mjera zaštite.

Waste from the sea bottom in shallow coastal waters can be easily removed by organising diving environmental activities. Diving clubs have a great potential in such activities to remove significant waste quantities. However, these activities cannot be carried out without a harmonised methodology and coordination, in which case we remain without data on the areas, quantities and compostion of the collected waste that play a significant role in the development of marine waste reduction strategies. A development of efficient measures for marine waste reduction is necessary for preserving biological and economic quality of marine and coastal environments. The paper presents a potential of diving activities in the cleanup of shallow coastal waters and reduction of marine waste quantities in Croatia. A need for cooperation between diving clubs and scientific institutions is particularly emphasized as a manner to obtain high quality data on the collected marine waste, and the importance of a harmonised manner of data collection that could significantly contribute to new insights into the current situation and trends, including adoption of adequate recommendations and legal protection measures.

Kljunasta končarica Nemichthys scolopaceus Richardson, 1848 (Pisces: Nemichthydae), novi pripadnik ihtiofaune Jadranskog mora

The paper reports the first record of Nemichthys scolopaceus leptocephalus in the Adriatic Sea, including a detailed description of the specimen with morphometric measurements and meristic counts. A single leptocephalus specimen was caught on 18th September 2016 in south Adriatic with a small mid-water trawl at a depth of approx. 120 meters. Further research is needed to reveal more information about the distribution and potential spawning and nursery areas of slender snipe eel as well as the mechanism of retention and dispersion of their larvae in the Adriatic.U radu je prikazan prvi nalaz vrste kljunasta končarica Nemichthys scolopaceus, ulovljen 18. rujna 2016. godine u južnom Jadranu pelagičkom kočom na dubini od cca. 120 metara. Nalaz se odnosi na ličinku leptocefala te uključuje detaljan opis jedinke s morfometrijskim i merističkim oso- binama. Svakako su potrebna daljnja istraživanja kako bi se otkrilo više o rasprostranjenosti i poten- cijalnim područjima mrijesta i hranilištima ove vrste, kao i o mehanizmu raspršivanja i zadržavanja njihovih ličinki u Jadranu

El gallano, Labrus mixtus (Pisces: Labridae): índices biológicos para documentar la historia vital de la especie y contribuir a su conservación

The cuckoo wrasse, Labrus mixtus, is widely distributed in the moderate warm waters of the Atlantic Ocean, including the Mediterranean and Adriatic Seas. Generally, labrids are small inshore coastal species susceptible to anthropogenic habitat degradation and, although without commercial importance, they make up a significant part of the by-catch and discard. Also, these fishes are intensively caught in recreational and subsistence fisheries. Basic biological information is required for their stock assessment and conservation. Studies of the age, growth, reproduction and feeding of L. mixtus have not been undertaken previously in the Adriatic Sea. The observed maximum age of the cuckoo wrasse was 10 years, although most of the sampled fish were 7 years old. The estimated parameters of the von Bertalanffy growth model suggested that the growth of L. mixtus was relatively fast in the first four years of life. L. mixtus is a protogynous hermaphrodite and sex change occurred at 26 cm, while the greatest increase in gonadosomatic index in April confirmed spring as the spawning period. The cuckoo wrasse is an opportunistic predator, feeding primarily on crustaceans, gastropods and fishes. The information provided on biological indices is necessary for life history pathways and future conservation measures of this population in the Adriatic Sea.El gallano, Labrus mixtus, se halla ampliamente distribuido en las zonas templadas del Océano Atlántico, incluyendo el Mediterráneo y el Mar Negro. En general, los lábridos son especies de pequeño tamaño que habitan en aguas costeras, siendo vulnerables a la degradación antrópica del hábitat y, a pesar de ser comercialmente poco importantes, forman una parte importante de los descartes de la pesca profesional. Estos peces también son intensamente capturados por la pesca recreativa o de subsistencia. Se requiere, pues, una información biológica básica para conocer el estado de los stocks y asegurar su conservación. Los estudios sobre la edad, el crecimiento, la reproducción y la alimentación de L. mixtus no se han realizado hasta ahora en el Adriático. La edad máxima observada en esta especie ha sido de 10 años, si bien la mayoría de los peces capturados se situaba en los 7 años. Los parámetros estimados a partir de la ecuación de crecimiento de Von Bertalanffy sugieren que el crecimiento de L. mixtus es rápido durante los primeros años de vida. L. mixtus es una especie hermafrodita proterogínica y el cambio de sexo se produce a los 26 cm de longitud, mientras que el gran incremento del índice gonadosomático en el mes de abril confirma que el periodo de reproducción se produce durante la primavera. El gallano es un depredador oportunista que se alimenta preferentemente de crustáceos, gasterópodos y peces. La información que se da en este artículo sobre los índices biológicos es necesaria para conocer las características vitales de esta especie y para adoptar futuras medidas de conservación de su población en el Adriático

BIOLOGICAL AND ECOLOGICAL CHARACTERISTICS, DISTRIBUTION AND CONSERVATION STATUS OF NERETVAN RUDD, Scardinius plotizza (HECKEL AND KNER, 1858) (PISCES, CYPRINIDAE) IN THE HUTOVO BLATO WETLAND, BOSNIA AND HERZEGOVINA

U ovom su radu izneseni podaci o biološko-ekološkim osobitostima, rasprostranjenosti i staništima, te uzrocima ugroženosti i potrebama za zaštitom peškelja Scardinius plotizza (Heckel i Kner, 1858) (Pisces, Cyprinidae), endemične vrste donjeg toka rijeke Neretve u Hrvatskoj i Bosni i Hercegovini. Na području močvare Hutovo blato u Bosni i Hercegovini peškelj je brojno zastupljena endemična vrsta. Rezidentan je i uglavnom rasprostranjen u hladnijim vodenim površinama Gornjeg blata, poput jezera Deran gdje naseljava središnja dublja područja obrasla podvodnom vegetacijom. U izboru staništa opažene su manje razlike između nedoraslih i odraslih populacija. Premda se trenutačni populacijski položaj ove vrste u Hutovom blatu može ocijeniti stabilnim, ukoliko se nastavi trend raznih negativnih utjecaja koji ugrožavaju njegovu opstojnost, budućnost mu se može smatrati ugroženom. Močvarno područje Hutovog blata, koje se odlikuje velikim brojem endemičnih vrsta uskog područja rasprostranjenosti, ugroženo je značajnim negativnim promjenama staništa, te su nužne hitne mjere procjene ugroženosti i provedbe zaštite. U cilju zaštite statusa ove vrste, kao i visoke ihtiološke raznolikosti područja, od posebne su važnosti djelotvorna zaštita staništa zajedno s poboljšanim mjerama vodnog gospodarenja i sprječavanjem daljnjeg unošenja i širenja alohtonih vrsta. Također, potrebno je precizno odrediti sistematsko-taksonomski položaj ove vrste. Na osnovi trenutačnog položaja, kao i projekcije budućeg razvoja i IUCN kriterija, predlaže se donošenje IUCN statusa gotovo ugrožen (NT) u Bosni i Hercegovini.This paper presents data on the biological and ecological characteristics, distribution and habitat, vulnerability and the need for protection of Neretvan rudd Scardinius plotizza (Heckel and Kner, 1858) (Pisces, Cyprinidae), an endemic species of the lower River Neretva in Croatia and Bosnia and Herzegovina. In the area of Hutovo Blato wetland in Bosnia and Herzegovina, this species are numerously represented. It is a resident species and generally prevalent in the colder water areas of the Gornje Blato, such as Lake Deran where it inhabits the deeper central area covered with underwater vegetation. In the choice of habitat, less difference between juvenile and adult populations was observed. Although the current population status of this species in the Hutovo Blato may be assessed as stable, it is likely to be considered endangered in the future if the trends of various negative impacts that threaten its existence prolong. The wetland area of the Hutovo Blato, which is characterized by a large number of endemic species of narrow distribution range, is threatened by significant negative changes in habitat, hence urgent evaluation and protection measures are needed. In order to improve the conservation status of this species, as well as high ichthyological diversity of this area, of particular importance are the following: effective protection of habitat, improved water management measures and prevention of further introduction and spreading of exotic species. Also, it is necessary to accurately determine its taxonomic position. It is proposed that IUCN classifies this species as Near Threatened (NT) in Bosnia and Herzegovina on the basis of its current status, as well as projections for future development and the IUCN criteria

Characterization of Microplastics in Prapratno Beach Sediment

Mikroplastika predstavlja ozbiljan problem u morskom i priobalnom okolišu. Analiziran je uzorak mikroplastike iz sedimenta plaže Prapratno na poluotoku Pelješcu, Hrvatska. Uzorkovanje i laboratorijsko odvajanje provedeni su prema DeFishGear protokolu. Svaki ispitak svrstan je u određenu kategoriju te je svakom određena masa, boja, prozirnost, maksimalna dimenzija i površina. Identifikacija je provedena infracrvenom spektroskopijom (FTIR) – HATR tehnikom. Otpad s plaže Prapratno sastoji se uglavnom od polietilena te, u manjem udjelu, od polistirena i polipropilena. Ovo djelo je dano na korištenje pod licencom Creative Commons Imenovanje 4.0 međunarodna.Microplastics represent a major problem in the marine and coastal environment. In this work, microplastics from the sediment of Prapratno beach on the Pelješac Peninsula (Croatia) were analysed. Sampling and laboratory separation were performed according to the DeFishGear protocol (Derelict Fishing Gear Management System in the Adriatic Region). The microplastic waste from Prapratno beach sediment consisted of 116 specimens, which could be classified into 6 micro litter categories according to EU TG ML Master List (Fig. 1). Fragments were found to be the predominant category of microplastic waste from the sediment of Prapratno beach, followed by granules, films, pellets and foams, which were present in approximately the same number, while filaments were the least represented category (Fig. 2). The most important categories by mass were granules and fragments, followed by pellets, while films, foams and filaments made up a very small content of the total sample mass (Fig. 3). The numerical contents (Fig. 4), did not correspond to the mass contents (Fig. 3) of individual categories due to the different densities and thicknesses of the specimens in each category. Almost all the base colours were present in the analysed samples (Fig. 5), while 90.52 % of specimens were opaque (Fig. 6). The maximum dimension and surface area of each specimen was determined by Digimizer Image Analysis Software. Maximum dimensions in the range of 1–5 mm were observed in 52.59 % of the specimens, thus belonging to large microplastics (LMP), while 47.41 % of the specimens had maximum dimensions in the range of 5–20 mm, thus belonging to so-called mezzo litter. The distribution of specimen dimensions within LMP is shown in Fig. 8, and within mezzo litter in Fig. 9. The fraction of each category in the total sample surface area is shown in Fig. 10. These results are similar to the numerical fractions of categories, since the samples were generally in the narrow range of maximum dimensions, and thus their numerical fractions corresponded to their fraction in the total surface of the sample. Identification of plastic material was performed by infrared spectroscopy, HATR technique. The obtained spectra were compared with the spectra in the database (Fig. 11–13). The results showed (Fig. 14) that the microplastic waste from Prapratno beach was made of polyethylene (82.46 %), polystyrene (11.40 %) and polypropylene (6.14 %). These polymers came from plastic packaging since polyethylene, polystyrene and polypropylene are the most used polymers for plastic packaging.

Hrvatski priobalni ribolov i stanje njegovih priobalnih resursa na pragu ulaska u EU: učinkovitost konvencionalnog gospodarenja i buduća perspektiva

Artisanal fisheries in Croatia and throughout the Mediterranean coastal region have a long tradition. In recent times the booming growth of human populations along Mediterranean coasts has led to harvesting of its marine resources in almost insupportable quantities, thus placing the research of this topic in a complex context. At the same time, fisheries management throughout the Mediterranean region has remained conventional in its nature, implying that it is almost only based on gear specific management provisions. The current Croatian legislative framework and legislative changes of artisanal fisheries regulation in the last 15 years, as well as how these changes have impacted on the state of coastal fish resources, particularly target species condition, are discussed. The conclusion is that if we want to improve further the state of the resources a more comprehensive set of management measures incorporating closed areas and a new approach actively involving fishers in the management process should be adopted. Finally, guidelines for future management in terms of the monitoring and data collection framework (DCF) proposed by the EU are demonstrated.Priobalni ribolov u Hrvatskoj i cijelom priobalnom dijelu Sredozemlja ima dugu tradiciju. Zadnjih godina, ubrzani rast ljudske populacije uzduž obale Sredozemlja dovelo je iskorištavanje morskih resursa do gotovo iscrpljujućih količina što istraživanja ove problematike postavlja u složeni kontekst. Istovremeno, gospodarenje ribarstvom u Sredozemlju ostalo je konvencionalno u svojoj naravi što znači da je gotovo potpuno temeljeno na propisivanju specifičnih karakteristika ribolovnih alata. U radu se iznosi i raspravlja o trenutnom okviru hrvatskog zakonodavstva i zakonskim promjenama u reguliranju priobalnog ribolova u zadnjih 15 godina, te kako su te promjene utjecale na stanje priobalnih resursa, posebice na stanje ciljanih vrsta. Zaključak je da ako želimo poboljšati stanje resursa, moramo uvesti cijeli niz jasnih gospodarskih mjera koje će uključivati zone zabranjenog ribolova, ali i novi pristup koji će aktivno uključivati ribare u procese gospodarenja. Na kraju su iznesene osnovne smjernice budućeg gospodarenja u smislu praćenja i prikupljanja podataka kako to predlaže i traži EU za sve zemlje članice
