Yellowtail flounder, redfish (Sebastes spp.) and witch flounder indices from the Spanish Survey conducted in Divisions 3NO of the NAFO Regulatory Area
Since 1995, Spain carries out a spring stratified random bottom trawl survey in Div. 3NO of the
NAFO Regulatory Area. Total mean catches, biomass and mean numbers for yellowtail flounder
(Limanda ferruginea) are presented for the period 1995-2017, for redfish (Sebastes spp.) for the
period 1997-2017 and for witch flounder (Glyptocephalus cynoglossus) for the period 2002-2017.
Detailed indices are presented from 2013. Yellowtail flounder indices do not show a clear trend.
Biomass increased from 1997 to 1999 and then remained almost constant throughout all the
period, decreasing slightly in 2014-2017. The 2017 value is the lowest since 1998. Redfish indices
oscillate greatly over time, probably because the gear does not sample adequately aggregating
pelagic species. There was a sharp increase in 2009 and since then until 2015, biomass fluctuated
maintaining higher values than before 2009. In 2016 biomass dropped and increase again in 2017
to the 2012 level. The 3N division comprises around the 90% of the total biomass in the last years.
Good year classes have not been registered recently. Witch flounder is very scarce and its indices
fluctuated throughout the series reaching the minimum value in 2014 and increasing since 2015.
2017 value is among the highest in the series. Recruitment was quite good at the beginning of the
series but poor in recent year
Síndrome hemofagocítico secundario a leishmaniasis visceral en un lactante: a propósito de un caso
El síndrome hemofagocítico (SHF) es un trastorno caracterizado por la activación y proliferación no maligna del sistema inmune. Puede ser primario o secundario. La forma primaria está ligada a factores genéticos autosómicos recesivos y la secundaria se presenta subsiguiente a otras enfermedades. La leishmaniasis es la parasitosis que más comúnmente lo gatilla y tiene la característica que resuelve con su tratamiento específico, sin el cual la mortalidad alcanza el 100 %.
Se presenta el caso de un niño de 7 meses, oriundo de Paraguay, que ingresa a nuestro Hospital por fiebre y hepatoesplenomegalia, que luego de arribar al diagnóstico y realizar tratamiento específico, evolucionó favorablemente.Hemophagocytic syndrome (HPS) is a disorder characterized by non-malignant activation and proliferation of the immune system. It can be primary or secondary. The primary form is linked to autosomal recessive genetic factors and the secondary form occurs subsequent to other diseases. Leishmaniasis is a parasitic disease with a wide worldwide distribution caused by different species of Leishmania. It is the protozoan that most commonly triggers it and it resolves with its specific treatment.
Without it, the mortality rate is 100 %.
We report the case of a 7-month-old boy, born in Paraguay, who was admitted at our Hospital with fever and hepatosplenomegaly, who after reaching the diagnosis, received specific treatment and developed a favorable clinical outcome
Results for Greenland halibut, American plaice and Atlantic cod of the Spanish survey in NAFO Div. 3NO for the period 1997-2019
Greenland halibut (Reinhardtius hippoglossoides), American plaice (Hippoglossoides platessoides) and Atlantic
cod (Gadus morhua) indices from the bottom trawl survey that Spain carries out in Spring since 1995 in Div.
3NO of the NAFO Regulatory Area are presented. Biomass, stratified mean catches and mean number per tow
for the three species are presented since 1997, year in which the survey extended the depth strata. Mean catch
per tow, length distribution and age distribution (this last except for American plaice) are presented for the
last five years (2015-2019).
Greenland halibut biomass and abundance estimates presented a decreasing trend since 1999, cut in 2007-
2009 with a high increase. In 2011 the biomass drops under the 2008 value, being stable since then until 2014
with a slight increase in 2015-2019 comprising a big increase in 2017, reaching the maximum of the series. In
last years it can be seen a presence of juveniles, mainly in 2004, but the greatest lengths have failed, although
in 2009 there is a quite good presence of individuals of ages 6-7 and in 2010 between 5-7. In 2011-2019 the
presence of all ages is poor. In 2018 the mode was at 1-2 years, and 2-3 years in 2019, suggesting a fairly strong
2017 cohort. For American plaice we can see a slightly increasing trend from 1999 to 2015, reaching a
maximum of mean catch and number in 2006, and a severe decline since 2016, being the 2019 the lowest value
of the entire series. The greatest recruitment in the presented series occurred in 2004 and we can follow their
mode along the years. No good recruitments were seen since then. In last years the level of all the ages is low.
No 2019 age indices are available at this moment. For Atlantic cod, it can be seen a low biomass until 2008,
being higher and variable since then, reaching a historical maximum in 2014. From 2015, biomass decreased
reaching in 2019 poor values at the level of the 2005 biomass. In 2007-2008 the youngest length classes were
much over the rest of the length classes. With the 2006 cohort the series reaches the maximum number of its
historical values at five years in 2011. There have been no good recruitments since 2009, although in 2015 and
2016 a discrete presence of individuals of age 1 can be seen

Informe de resultados de la Campaña Panamá Miguel Oliver 2007, B/O Miguel Oliver
Equipo de Pesquerías Lejanas, Centro Oceanográfico de VigoLa Campaña Panamá M.O. 2007 es la primera Campaña española de investigación realizada en aguas panameñas del Océano Pacífico, su objetivo fue obtener índices de abundancia y conocer la estructura de las poblaciones de las especies comerciales en el área.
Esta campaña se desarrolló con el buque oceanográfico Miguel Oliver. La Campaña de llevó a cabo, mediante la colaboración entere el IEO y la SGPM, con participación panameña.
Los fondos, volcánicos, resultaron abruptos siendo imprescindible la prospección batimétrica, realizada con sonda multihaz. Se realizaron un total de 51 pescas en un rango de profundidad de 153 a 1236 m.
Los resultados preliminares de la Campaña muestran como especie dominante en número y peso a la “pajarita” (Peprilus snydery) con 7919 Kg., seguida de la argentina (Argentina aliceae), 1470,7 Kg. y del camarón “cabezón” (Heterocarpus vicarius), 1104.3 Kg. Otras especies importantes fueron: Diablico (Pontinus sierra); Sable (Trichiurus lepturus); Doncella (Hemanthias signifer); Langostino chileno (Pleuroncodes planipes); Corbina blanca (Cynoscion phoxocephalus). Los peces mostraron, en general, una distribución de tallas con predominio de individuos juveniles y modas menores de 20 cm. en casi todos los casos.
La presencia de camarones de profundidad podría permitir el desarrollo de una pesquería en fondos no explotados actualmente.The Panamá M.O. 2007 bottom trawl is first Spanish research survey in Panamanian Pacific waters.The principal aim was obtain preliminary indices of abundance and know the structure of populations of commercial species in the area. This survey was developed with the RV Miguel Oliver. The survey was carrying out by the IEO aware collaboration and SGPM, involving Panama. The rugged volcanic funds became necessary preliminary probe multibeam surveys A total of 51 catches in a depth range of 153 to 1236 m.
Preliminary results show as the dominant species in number and weight to the Peprilus snydery with 7919 kg, followed by Argentina (Argentina aliceae), 1470.7 kg of shrimp Heterocarpus vicarius, 1104.3 Kg Other important species were: Speckled scorpionfish (Pontinus sierra), Largehead hairtail (Trichiurus lepturus), Maiden Damsel bass (Hemanthias signifer); pelagic red crab (Pleuroncodes planipes) Cachema Weakfish (Cynoscion phoxocephalus). The fish generally showed a distribution size dominated by juveniles, individuals bellow 20 cm. in almost all cases.
The presence of shrimp would make it possible to develop a fishery in funds not currently exploited
