Assessing the economic impact of key operational factors on grow-out farms producing European sea bass under different scenarios of production

The aim of this work is to evaluate how changes in a set of different key operational factors (e.g., the unit sales price, the fingerling unit cost, the feed unit cost, and so on) would impact on the economic performance of a typical grow-out farm producing European sea bass in the Mediterranean under different scenarios of production related to the farm size (production volume) and production strategy (size of the produced fish). A what-if analysis using a deterministic static model to simulate the annual income statement of a typical grow-out farm was carried out. Data was obtained from ten European facilities located in the Mediterranean Sea. Our findings show the importance of the farm’s scale and the production of larger fish to obtain better economic results. Another important conclusion is that increase in fish growth and survival rates, innovating in feed and improving the breeding and health conditions, could compensate the reductions in the sea bass sales prices more efficiently than using other alternatives.info:eu-repo/semantics/publishedVersio

Effectiveness of nonhormonal products for the treatment of women with vaginal atrophy. [Efectividad de productos no hormonales para el tratamiento de las mujeres con atrofia vaginal].

Objective: To describe the clinical progress of women with vaginal atrophy who receive nonhormonal treatment. Material and methods: Single-center retrospective longitudinal observational descriptive study in postmenopausal women aged 45-60 years with symptoms of vaginal atrophy who required nonhormonal treatment. Results: We included 98 women with a mean (SD) age of 54.6 (3.2) years and a mean time of 5.6 (3.0) years without menstrual periods. Of these, 63.3% were treated with hyaluronic acid and Centella asiatica cell lysate and the other 36.7% with glycerin and polycarbophil. The vaginal maturation index improved significantly after 3 months of treatment with hyaluronic acid and Centella asiatica: the parabasal cell count declined (-8.4%; 95%CI, –10.6 to –6.2; p=0.001) and the intermediate cell count increased (3.6%; 95%CI, 2.0-5.3; p=0.001), as did that of superficial cells (4.8%; 95%CI, 3.8-5.7; p=0.001). In addition, all symptoms and signs of vaginal atrophy improved after 3 months with treatment with hyaluronic acid and Centella asiatica lysate. There was no significant change in the vaginal maturation index or in symptoms and signs after 3 months of treatment with glycerin and polycarbophil. Conclusions: Three months of nonhormonal treatment with hyaluronic acid and Centella asiatica lysate significantly improved the vaginal maturation index.post-print346 K

Growth of Octopus vulgaris (Cuvier, 1797) in tanks in the Ebro Delta (NE Spain): effects of temperature, salinity and culture density

To assess the possibility of O. vulgaris ongrowing using tanks or cages in the bays of the Ebro Delta, we performed several growth trials of common octopus held in tanks. Effects of environmental factors (temperature and salinity) and zootechnical aspects (culture density) were studied. The thermal ranges that defined positive growth periods in the bays of the Ebro Delta were 19.5ºC to 23ºC (spring-summer) and 23.5ºC to 12.3ºC (autumn-winter), the latter being the most suitable period for ongrowing. Salinity did not affect survival (100%) or growth within the range tested (34-29 psu), though feeding rates (AFR, SFR) were directly related to salinity. On the other hand, after 60 days, final culture density increased three-fold (D1: 12.36 → 44.37 kg m–3; D2: 24.13 → 67.76 kg m–3), with optimal survival results (>90%) for the two densities tested. Growth and feeding rates showed a slight inverse relationship with density. Finally, growth and feeding rates showed a clear dependence on temperature in the two experiments (density and salinity). Our results conclude that industrial production of O. vulgaris in tanks is promising: this system offers an alternative to cages and allows for a more exhaustive control of culture.Con el fin de evaluar la posibilidad de engorde de O. vulgaris en tanques o jaulas en las bahías del Delta del Ebro, se llevaron a cabo varias experiencias de crecimiento de individuos mantenidos en tanques. Se estudiaron tanto aspectos medioambientales (temperatura y salinidad) como zootécnicos (densidad de cultivo). Los rangos térmicos que definieron periodos positivos de crecimiento en las bahías del Delta del Ebro fueron: 19.5ºC-23ºC (primavera-verano) y 23.5ºC-12.3ºC (otoño-invierno), siendo este último el periodo más favorable para el engorde. La salinidad no afectó a la supervivencia o al crecimiento dentro del rango testado (34-29 psu), a pesar de que las tasas de alimentación (AFR, SFR) mantuviesen relación directa con la salinidad. Por otro lado, y transcurridos 60 días, observamos que la densidad de cultivo se multiplicó por tres (D1: 12.36 → 44.37 kg m–3; D2: 24.13 → 67.76 kg m–3), con resultados óptimos de supervivencia (>90%) bajo las dos condiciones probadas. Las tasas de crecimiento y alimentación mostraron una relación indirecta con la densidad de cultivo. Finalmente, se observó que tanto las tasas de crecimiento como las de alimentación presentan una clara dependencia de la temperatura en ambas experiencias (salinidad y densidad de cultivo). Nuestros resultados concluyen que la producción industrial de O. vulgaris en tanques es prometedora: este sistema ofrece una alternativa a las cajas y permite un control más exhaustivo del cultivo

Proizvodnja galne i elagične kiseline biorazgradnjom tanina iz biljaka Larrea tridentata i Fluorensia cernua

In the present work, the production of two potent antioxidants, gallic and ellagic acids, has been studied using solid-state fermentation (SSF) of tannin-rich aqueous plant extracts impregnated in polyurethane foam. Extracts from creosote and tar bush were ino-culated with Aspergillus niger PSH spores and impregnated in the polyurethane support.The kinetics of the fermentation was monitored every 24 h. The maximum biodegradation of hydrolysable and condensed tannins was, respectively, 16 and 42 % in creosote bush, and 40 and 83 % in tar bush. The maximal productions of gallic and ellagic acid (152 and177 %, respectively) were reached with aqueous extracts of creosote bush. Tar bush extracts inoculated with A. niger PSH spores produced only gallic acid (92 %), while ellagic acid was not recovered after the fermentation process. Results demonstrated the potential use of these plants as a source for the production of antioxidants.U ovom je radu istražena proizvodnja dvaju jakih antioksidanasa, galne i elagične kiseline, na čvrstoj podlozi taninom bogatih ekstrakata impregniranih poliuretanskom pjenom. Ekstrakti biljaka Larrea tridentata i Fluorensia cernua inokulirani su sporama plijesni Aspergillus niger PSH i zatim impregnirani poliuretanskom pjenom. Kinetika procesa praćena je svakih 24 sata. Maksimalna biorazgradnja hidroliziranih tanina iznosila je 16 % u ekstraktu biljke L. tridentata i 40 % u ekstraktu biljke F. cernua, dok je maksimalna biorazgradnja kondenziranih tanina bila 42 i 83 %. Maksimalna proizvodnja galne (152 %) i elagične kiseline (177 %) postignuta je primjenom vodenog ekstrakta biljke L. tridentata. Uporabom ekstrakta biljke F. cernua, inokuliranog sporama A. niger PSH, proizvedena je samo galna kiselina (92 %), dok prisutnost elagične kiseline nije utvrđena nakon završetka procesa. Rezultati dokazuju da se te dvije biljke mogu upotrijebiti za proizvodnju antioksidanasa

Competitive Management of Sugarcane Waste and Reduction of CO2 Emissions from Harvest Burning in Supply Regions

Sugarcane is an important crop in more than 100 countries around the world. Their burning is a cultural activity before and after the harvest; however, pollutants and greenhouse gases emitted to the atmosphere can affect the human health and weather, respectively. The aim of this research is to report the CO2 emissions of the main countries dedicated to the cane production and explain their relevant relation with the dry matter available to the burn and how it can affect their alternative uses. The methodology used in this study identifies the relation between biomass burned (dry matter) and CO2 emissions, estimated by the Food and Agriculture Organization of the United Nations with the techniques of the Intergovernmental Panel on Climate Change. The study was carried out for the period of 1990–2014. The results show an important positive trend in the increase in the annual production levels and the biomass burned during the harvest period. The high correlation between harvested area and yield per hectare in countries such as Brazil and the United States allows to have more biomass available for alternative uses. Countries such as Mexico and Colombia have a low correlation between both the parameters due to the increase in the harvested hectares and reduction of their performance per hectare

Mikrobna proizvodnja antioksidativnih dodataka hrani na čvrstoj podlozi od kore šipka (Punica granatum) i lišća grma Larrea tridentata

In this work, creosote bush (Larrea tridentata) leaves and pomegranate (Punica granatum) peels were characterized for their use as a source of antioxidants and a support in solid-state fermentation. This work focuses on the kinetic evaluation of physicochemical changes during the fungal fermentation of two tannin-rich plant materials, mainly on the polyphenolic content. Aspergillus niger GH1 was used in the fermentation processes, the cultures were monitored for 96 h. The content of proteins, crude fibres, lipids, reducing and total sugars was evaluated following the AOAC methods. Tannins were analyzed using a spectrophometric method. Biodegradation of ellagitannins was monitored kinetically and the accumulation of gallic and ellagic acids was determined by HPLC. Results demonstrated that pomegranate peel and creosote bush leaves are excellent supports for solid-state fermentation and sources of antioxidants.U radu je istražena mogućnost primjene lišća grma Larrea tridentata i kore šipka (Punica granatum) kao sirovina za dodatak čvrstim podlogama te proizvodnju antioksidanasa. U središtu je istraživanja kinetička procjena fizikalno-kemijskih promjena tih taninima bogatih sirovina, ističući promjenu udjela polifenolnih spojeva tijekom procesa. Za proces je upotrijebljen soj plijesni Aspergillus niger GH1, koji je praćen tijekom 96 sati. Određen je udio proteina, sirovih vlakana, lipida, te ukupnih i reducirajućih šećera standardnim AOAC metodama, a udio i sastav tanina ispitani su Folin-Ciocalteau metodom. Kinetički je praćena biodegradacija elagitanina, a nakupljanje galne i elagične kiseline utvrđeno je HPLC metodom. Dobiveni rezultati pokazali su da su kora šipka i lišće grma Larrea tridentata izvrsne sirovine za čvrste podloge i dobar izvor antioksidanasa

Mapping the knowledge of the main diseases affecting sea bass and sea bream in Mediterranean

Good knowledge on the disease situation and its impact on production is a base mechanism for designing health surveillance, risk analysis and biosecurity systems. Mediterranean marine fish farming, as any aquaculture production, is affected by various infectious diseases. However, seabass and seabream, the main produced species, are not listed as susceptible host species for the notifiable pathogens listed in the current EU legislation, which generates a lack of systematic reporting. The results presented in this study come from a survey directly to fish farms (50 hatchery and ongrowing units from 10 Mediterranean countries), with data from 2015‐2017, conducted by the H2020 project MedAID. Seabass showed a higher survival rate (85%) through a production cycle than seabream (80%) in spite of equal mortality due to pathogen infections (10%). The differences in survival may be explained by mortality “of other causes”. Seabream and seabass have different disease profiles, and the profile is slightly different between geographical regions. Among the most important diseases, tenacibaculosis and vibriosis were identified in seabass and Sparicotyle chrysophrii (a gill fluke) and nodavirus in seabream. Correlating mortality data to management variables showed that increasing density, buying fingerlings from external sources, and treatments due to disease are factors that negatively influence mortality rate. Most of the surveyed farms did not keep sufficient quality data to implement good health status reports and perform detailed impact studies, which shows the necessity of updating the current legislative framework to provide the basis for better reporting of relevant pathogens in the Mediterranean basin.info:eu-repo/semantics/publishedVersio

Influence of sugarcane burning on soil carbon and nitrogen release under drought and evapotranspiration conditions in a Mexican sugarcane supply zone

"Sugarcane cultivation is an agricultural activity of worldwide importance. This crop has been cultivated in Mexico for centuries, impacting important productive areas like the study region called Huasteca Potosina which is located at the Central-East part of Mexico. The relationship between soil conditions, weather and production per hectare allows identifying the edaphological and climatic conditions (aptitude levels) for cultivating sugarcane in the study area. The objective of this research work is to analyze the relation between the cultivated hectares and production of sugarcane. Likewise, to explain its behavior and interpret the contribution of N and C released to the atmosphere for burning sugar cane in association with events and meteorological parameters involved in the flux of water between soil and atmosphere such as drought, evapotranspiration and rainfall. The methods and indicators for burning waste provided by the Intergovernmental Panel on Climate Change (IPCC), the value of potential evapotranspiration as Thornthwaite and drought severity index were applied in order to understand the correlations between the drought severity index and potential evapotranspiration, and between C and N release and potential rainfall availability. The results show the increment of harvested hectares and the loss of water from the soil by the increase of periods of drought events and evapotranspiration. The volatilized nutrients in soil varied from 1.32 x 105 to 2.17 x 105 t for C and from 1.32 x 103 t to 2.17 x 103 t for N during the burning of sugarcane, affecting production levels with values fluctuating between 38 t/ha to 77 t/ha for the term of 1990-2010.""El cultivo de caña de azúcar es una actividad agrícola de importancia mundial llevada a cabo en México durante siglos, impactando importantes áreas productivas como la región de estudio llamada Huasteca Potosina, localizada al este central de México. La relación entre las condiciones del suelo, clima y producción por hectárea permite identificar las condiciones edafológicas y climáticas (niveles de aptitud) para cultivar la caña de azúcar en el área de estudio. Bajo este contexto, el objetivo fue analizar la relación entre las hectáreas cultivadas y la producción de caña de azúcar y explicar su comportamiento al interpretar las contribuciones del N y C liberados a la atmósfera por la quema de caña asociados a eventos y parámetros meteorológicos involucrados en el flujo de agua entre el suelo y la atmósfera como sequía, evapotranspiración y lluvia. Los métodos e indicadores para la quema de residuos provistos por el Panel Intergubernamental del Cambio Climático (IPCC. por sus siglas en inglés), el valor de la evapotranspiración potencial por Thornthwaite y el índice de severidad de la sequía fueron aplicados para comprender las correlaciones entre el índice de severidad de la sequía y la evapotranspiración potencial, así como entre el C y el N liberados y la disponibilidad potencial de lluvia. Los resultados muestran el incremento en las hectáreas cosechadas y la pérdida de agua del suelo por el aumento de los periodos de sequía y la evapotranspiración. Los nutrientes del suelo volatilizados, varían de 1.32 x 105 ton a 2.17 x 105 ton para C y 1.32 x 103 ton a 2.17 x 103 ton para N durante la quema de caña de azúcar, lo que afecta sus niveles de producción con valores que fluctúan entre 38 t/ha y 77 t/ha durante el periodo 1990-2010.
