The interspecific preferences of fishes for different depths and habitats suggest fishers could avoid unwanted catches of some species while still effectively targeting other species. In pelagic longline fisheries, albacore (Thunnus alalunga) are often caught in relatively cooler, deeper water (>100 m) than many species of conservation concern (e.g., sea turtles, billfishes, and some sharks) th...

At least 100 fish species are known to be present in the intertidal areas (estuaries, mudflats and salt marshes) of Mont Saint-Michel Bay. These and other comparable shallow marine coastal waters, such as estuaries and lagoons, play a nursery role for many fish species. However, in Europe little attention has been paid to the value of tidal salt marshes for fishes. Between March 1996 and April ...

A study of European hake Merluccius merluccius gill net selectivity was undertaken off the Algarve (Southern Portugal), between 1999 and 2001. Four nominal mesh sizes (70, 80, 90 and 100 mm) were used in fishing trials and the ‘share each length class catch total’ (SELECT) method was used to fit gill net selectivity curves. Hake were caught in the same size range by all mesh sizes, between 17 a...

during this study from december 2009 to november 2011, 363deep flounder fish were caught and their weight and length were measured. the caught fish included 18 males, 200 females and 155 immature fishes. the mean, maximum and minimum total lengths were 264 ± 57 (mean ± sd), 415 mm and 115 mm respectively. the mean, maximum, and minimum total weights for this species were 238 ± 150 g, 827 g and ...

OBJECTIVE This study was conducted to determine the prevalence of Ligula intestinalis and infections caused by these on freshwater fish in rivers and streams in the Kars plateau of north-eastern Anatolia, Turkey. METHODS This research was conducted between April and July 2011. Fish samples were caught via a casting net and an electro-shocker. The samples were immediately examined to determine...

Developments in pop-up satellite archival tags (PSATs) have greatly improved scientific understanding of the postrelease survival, behavior, and movements of marine vertebrates—animals from which it is not always practical to physically recover tags to obtain data (Arnold and Dewar, 2001; Graves et. al. 2002). PSATs take measurements of physical conditions (e.g., temperature, pressure, light le...

The objective of this study was to describe the morphology and morphometry saggitta otoliths Polydactylus virginicus, Menticirrhus cuiaranensis Conodon nobilis in a tropical environment. Fishes were caught with rod reel competitive fishing events promoted 2014-2015 along coast Sergipe. A total 174 pairs sagitta P. 181 M. 77 C. extracted. In general, all three species analyzed here presented dif...

one of the most important problems of fish is the short shelf lifebecause of the high unsaturated fatty acids. so, with the help of antioxidant compounds can be increased shelf life of fish. the aim of this study was to investigate the effect of vitamin e as a natural antioxidant to increase shelf life of rainbow trout fillet during storage at refrigerator temperature (4±1 0c). treatments were ...
