Parasitol Res (2012) 110:1147–1157 DOI 10.1007/s00436-011-2605-z ORIGINAL PAPER Parasite communities and feeding ecology of the European sprat (Sprattus sprattus L.) over its range of distribution Sonja Kleinertz & Sven Klimpel & Harry W. Palm Received: 15 July 2011 /Accepted: 4 August 2011 /Published online: 18 August 2011 # Springer-Verlag 2011 Abstract The metazoan parasite fauna and feeding ecology Mollusca, Annelida, Crustacea and Tunicata. The highest of 165 Sprattus sprattus (L., 1758) was studied from number of prey organisms belonged to the crustaceans. The different geographic regions (Baltic Sea, North Sea, English variety of prey items in the stomach was reflected by the Channel, Bay of Biscay, Mediterranean Sea). A total of 13 parasite community differences and parasite species rich- metazoan parasite species were identified including six ness from the different regions. The feeding ecology of the Digenea, one Monogenea, two Cestoda, two Nematoda fish at the sampled localities was responsible for the and two Crustacea. Didymozoidae indet., Lecithocladium observed parasite composition and, secondarily, the zoo- excisum and Bomolochidae indet. represent new host geographical distribution of the parasites, questioning the records. The parasite species richness differed according use of the recorded sprat parasites as biological indicators to regions and ranged between 3 and 10. The most species- for environmental conditions and change. rich parasite fauna was recorded for sprats from the Bay of Biscay (North Atlantic), and the fishes from the Baltic Sea contained the lowest number of parasite species. More Introduction closely connected geographical regions, the North Sea, English Channel and Bay of Biscay, showed more similar Fish parasites are an integral part of every ecosystem and parasite component communities compared with more play an important role for the health of marine organisms. -

RESUMEN Una especie de Clupeiformes que ha sido habitual en las capturas de la flota pesquera artesanal que opera en el mar interior de Chiloé, Chile, ha sido confundida con la sardina común (Strangomera bentincki) y la sardina española (Sardinops sagax musica), cuyas distribuciones geográficas en esta área marcan su límite austral. Mediante un análi- sis de morfometría y recuentos de estructuras duras de siete ejemplares capturados en julio de 2005 y provenientes del área de pesca de Quicaví, Chiloé (42º17’S-73º22’W), se determinó, que correspondían a seis Sprattus fuegensis (Jenyns 1842) (sardina fueguina), y que ella estaría presente hegemónicamente en las capturas del mar interior de Chiloé; en la X Región administrativa de Chile. Basado en la captura de especímenes de S. fuegensis obtenidos en las cercanías de la Isla Guar, al norte de Calbuco en octubre de 2005, se realizó una breve descripción de otolitos y una comparación del diámetro longitudinal del primer anillo hialino entre ambas sardinas, mediante el uso del test no paramétrico de Mann-Withney; del mismo modo, se comparó la relación longitud del pez con el diámetro del otolito para ambas sardinas utilizando un ANCOVA. -

Here we analyzed the annual cycle of body condition factor (K), gonadosomatic index (GSI) and maturity of sprat from the Skagerrak and Kattegat as well as from the Skagerrak inner fjords (Uddevalla fjords). The results show an inverse yearly pattern for K and GSI in both areas, K being the highest in autumn and lowest in spring, while the GSI index was highest in spring and lowest in autumn. The annual highest proportion of spawning fish was recorded from May to July, indicating the late spring and early summer as the main spawning period for sprat in these areas. Male sprat reached maturity at a higher size in the Uddevalla fjords compared to Skagerrak and Kattegat, while negligible differences were shown by females. The K, GSI and size-at-age were the lowest in the Uddevalla fjords, while K and GSI were the highest in the Skagerrak, potentially related to the different environmental conditions encountered in the different areas. -

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. -
Spawning of Bluefin Tuna in the Black Sea: Historical Evidence, Environmental Constraints and Population Plasticity
Spawning of Bluefin Tuna in the Black Sea: Historical Evidence, Environmental Constraints and Population Plasticity Brian R. MacKenzie1*, Patrizio Mariani2 1 Center for Macroecology, Evolution and Climate, National Institute for Aquatic Resources (DTU Aqua), Technical University of Denmark, Charlottenlund, Denmark, 2 Center for Ocean Life, National Institute for Aquatic Resources (DTU Aqua), Technical University of Denmark, Charlottenlund, Denmark Abstract The lucrative and highly migratory Atlantic bluefin tuna, Thunnus thynnus (Linnaeus 1758; Scombridae), used to be distributed widely throughout the north Atlantic Ocean, Mediterranean Sea and Black Sea. Its migrations have supported sustainable fisheries and impacted local cultures since antiquity, but its biogeographic range has contracted since the 1950s. Most recently, the species disappeared from the Black Sea in the late 1980s and has not yet recovered. Reasons for the Black Sea disappearance, and the species-wide range contraction, are unclear. However bluefin tuna formerly foraged and possibly spawned in the Black Sea. Loss of a locally-reproducing population would represent a decline in population richness, and an increase in species vulnerability to perturbations such as exploitation and environmental change. Here we identify the main genetic and phenotypic adaptations that the population must have (had) in order to reproduce successfully in the specific hydrographic (estuarine) conditions of the Black Sea. By comparing hydrographic conditions in spawning areas of the three species of bluefin tunas, and applying a mechanistic model of egg buoyancy and sinking rate, we show that reproduction in the Black Sea must have required specific adaptations of egg buoyancy, fertilisation and development for reproductive success. Such adaptations by local populations of marine fish species spawning in estuarine areas are common as is evident from a meta-analysis of egg buoyancy data from 16 species of fish. -

Using catches presented by FAO on behalf of the USSR and Russian Federation as a baseline, total removals were estimated by adding estimates of unreported commercial catches, discards at sea, and unreported recreational and subsistence catches. Estimates for ‘ghost fishing’ were also made, but not included in the final reconstructed catch. Total removals by Russia were estimated to be 1.57 times the landings presented by FAO (taking into account USSR-disaggregation), with unreported commercial catches, discards, recreational, and subsistence fisheries representing an additional 30.6 %, 24.7 %, 1.0%, and 0.7 %, respectively. Discards reached their peak in the 1970s and 1980s during a period of intense bottom trawling for sprat that partially contributed to the large-scale fisheries collapse in the 1990s. -
