Widow rockfish: Proceedings of a workshop, Tiburon, California, December 11-12, 1980 [PDF]

open access: yes, 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 ...

Lengths of Stay and Stopover Strategies of Western Sandpipers During Migration at Two Sites in British Columbia, Canada

open access: yesEcology and Evolution, Volume 15, Issue 1, January 2025.
Stopover duration (length of stay, LOS) is a key variable in avian migration ecology that reflects behavioral decisions to obtain fuel or continue travel between breeding and non‐breeding areas. We find the LOS of Western Sandpipers differs between two important stopover sites on the Pacific Coast of Canada, reflecting different migration strategies ...

A preliminary study on the feeding regime of European pilchard (Sardina pilchardus Walbaum 1792) in Izmir Bay, Turkey, Eastern Aegean Sea [PDF]

open access: yes, 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

Deepwater Sharks at Their Northern Limits—Distribution, Diet and Trophic Relations

open access: yesMarine 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 ...

VARIACION ONTOGENETICA EN LA DIETA DE PATAGONOTOTHEN LONGIPES (STEINDACHNER 1876) (PERCIFORMES: NOTOTHENIIDAE) EN EL FIORDO DE CASTRO, CHILOE ONTOGENETIC VARIATION IN THE DIET OF PATAGONOTOTHEN LONGIPES (STEINDACHNER 1876) (PERCIFORMES: NOTOTHENIIDAE) IN THE FIORD OF CASTRO, CHILOE

open access: yesGayana, 2002
Patagonotothen longipes es un nototénido litoral que se distribuye geográficamente en Chile, desde Chiloé (42º29'S, 73º45'W) al sur. En el presente trabajo se analiza su ecología trófica, para lo cual se estudiaron 105 ejemplares capturados en ...

Which Novel Ingredient Should be Considered the “Holy Grail” for Sustainable Production of Finfish Aquafeeds?

open access: yesReviews 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

Euphausiacea diversity in a trans-oceanic transect through the South Atlantic Ocean: the first Atlantic record of Thysanopoda astylata Brinton, 1975

open access: yesAnais da Academia Brasileira de Ciências, 2019
: Information about euphausiids in central South Atlantic Ocean is scarce; hence, we investigated species composition and distribution of euphausiids along a longitudinal transect in this region, with an emphasis on Thysanopoda.

Oceanographic mechanisms that possibly explain dominance of neritic-tropical zooplankton species assemblages around the Islas Marías Archipelago, Mexico

open access: yesLatin American Journal of Aquatic Research, 2014
The nearshore zooplankton species assemblage, identified per taxonomic groups (20) and per species for 12 selected groups, was analyzed from samples collected during November 2010 at four volcanic islands of the Islas Marías Archipelago (IMA), located 90-

Diet variation and trophic impact of weakfish, Cynoscion regalis, within multiple marine habitats of the eastern United States

open access: yesJournal 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 ...
