the aim of this study was to determine the fatty acid and mineral composition in bone of 3 pelagic fish: gold stripe sardine (sardinella gibbosa), anchovy kilka (clupeonella engrauliformis) and indian anchovy (stolephorus indicus). fatty acid profiles showed that total saturated fatty acid have no significant differences in 3 species. the content of total mono saturated fatty acids in anchovy k...
the present study considered the situation of kilka stocks in last decades by using overfished biomass threshold, fishing effort ratio and fishing mortality proxy during 1991-2010. the cpue index of anchovy and mixed-species of kilka indicated an undepleted from 1991 to 2000. in 2000, the cpue ratio declined to close to the “in danger” region, and subsequently collapsed to “overfished” region f...
A major spawning ground of the European anchovy (Engraulis encrasicolus) population in the Bay of Biscay is located near the mouth of the Gironde estuary. Variations in the river discharge affect the supply of nutrients to the coastal marine area encompassing anchovy spawning grounds. Two “Pegase” cruises (May–June 1997 and 1998) observed two contrasting situations: with and without a superfici...
Seabirds as offshore wildlife resources have largely been unstudied by wildlife managers until recently. Brown pelicans (Pelecanus occidentalis californicus) in Southern California Bight (SCB) have received special attention in the past under the Endangered Species Act of 1973 (ESA). Special consideration is given to species with endangered status in commercial fishery management plans mandated...
The present study was carried out during 2006-2007 along the southern Caspian Sea. The species composition showed that the common kilka, Clupeonella cultriventris caspia, is dominant species with 89% and then anchovy, C. engrauliformis, has shown only 8.7% while it was already dominant species in the past decades. The overall results indicated that common kilka was replaced with anchov...
The northern anchovy, Engraulis mordax, was experimentally reared in the laboratory at the Southwest Fisheries Center, La Jolla, Calif. Data from three experiments were used to empirically fit a two-phase Gompertz growth model. The model describes growth from hatching to about 20 mo ofage. It was estimated that the average length oflaboratory-reared anchovies is 102 mm at 1 yr old and 119 mm at...
201 Comparison of ω-3 Fatty Acids by GC-MS in Frequently Consumed Fish and Fish Oil Preparations on the Turkish Market Summary : In this study, two fish species, anchovy (Engraulis encrasicholus) and horse mackerel (Trachurus trachurus), and three commercial fish oil products sold on the Turkish market were analyzed and compared by gas chromatography-mass spectrometry (GC-MS) according to their...
Invasions of ecosystems by exotic species have been the focus of a growing body of research in applied biology and ecology, but relatively little attention has been paid to their economic consequences. Even where economic estimates have been made these often make ad hoc assumptions about the biological relationships of interest and lack grounding in economic theory. This paper develops an integ...

Front. Mar. Sci. 4:275. doi: 10.3389/fmars.2017.00275 Understanding the Impact of Environmental Variability on Anchovy Overwintering Migration in the Black Sea and its Implications for the Fishing...
In coastal regions, age-0 juveniles of many fish species are capable of recruiting to either marine or estuarine nursery habitats, yet the ecological consequences for cohorts that use marine versus estuarine nurseries is poorly understood. In the present study, stable isotope (δ13C, δ15N) and stomach contents data were used to compare trophic ecology associated with differential habitat use for...
