Deepwater Sharks at Their Northern Limits—Distribution, Diet and Trophic Relations
Marine Ecology, Volume 46, Issue 1, January 2025.ABSTRACT Deepwater areas and continental slope regions south and west off Iceland are characterized by a relatively high species diversity and abundance of sharks that likely play a critical ecological role within this ecosystem. The study investigates trophic ecology of the sharks employing stomach content analysis and stable isotope analysis of ...

Reviews in Aquaculture, Volume 17, Issue 1, January 2025.ABSTRACT The immense production of fishmeal and fish oil is dramatically intensifying the severe state of pelagic fisheries overexploitation. The latter in conjunction with the increasing demand for low‐cost protein‐rich food supply prompt aquaculture to employ new practice. Several novel dietary ingredients are currently under evaluation for potential

A preliminary study on the feeding regime of European pilchard (Sardina pilchardus Walbaum 1792) in Izmir Bay, Turkey, Eastern Aegean Sea [PDF]
, 2005 The gut contents of Sardina pilchardus specimens captured in Izmir Bay were examined in order to determine their feeding regimes. Of the 365 stomachs examined, 321 (87.95%) contained food and 44 (12.05%) were empty. Analysis of gut contents verified that

Widow rockfish: Proceedings of a workshop, Tiburon, California, December 11-12, 1980 [PDF]
, 1987 This workshop was organized because of the increase between 1978 and 1980 in coastwide landings of widow rockfish, from less than 1,000 mt to more than 20,000 mt, and because of scientists' concern with the lack of knowledge both of the fishery and ...

Journal of Fish Biology, Volume 105, Issue 6, Page 1628-1642, December 2024.Abstract Weakfish (Cynoscion regalis) is not federally managed but feeds on species of management and ecological interest. We examined the trophic ecology of weakfish in Chesapeake Bay and the coastal and offshore waters of the eastern United States. For these areas, we determined the dominant prey of weakfish; identified how much diet variation was ...

Limnology and Oceanography, Volume 69, Issue 11, Page 2547-2563, November 2024.Abstract The carbon and nitrogen isotope ratios (δ13C and δ15N) of marine plankton record biogeochemical processes at the base of the food web. In the Southern Ocean, such data, predominantly from summer, have been used to infer surface CO2 concentrations and the potential for biological carbon export.
