In this study, we compared the bycatch reduction capacity of a trawl fitted with standard rigid sorting grid that newly developed, flexible system called Excluder. We conducted fishing trials in Norway pout (Trisopterus esmarkii) small-meshed fishery North Sea. Catch data were analysed by species and length using catch comparison ratio method. The Excluder significantly reduced (in weight) rela...

The Chirostoma "humboldtianum" group includes seven silverside species considered as a monophyletic assemblage because of their high genetic and morphological similarities. The group includes five moderately large species, "peces blancos" (117-300 mm standard length--SL) and two smaller species, "charales" (70-142 mm SL). These species are of great economical, cultural and ichthyological intere...

Impact of microplastic pollution on the marine environment and its biota is a major concern globally. Gulf Mannar (GoM) Palk Bay (PB) are two important biodiversity hotspots along south-east coast India. However, in recent years intense tourism fishery activities have made ecosystem these ecologically significant coastal zones vulnerable to contamination. Hence, comparative study seasonal distr...

Population parameters have been studied in nine of the 21 species barracudas reported globally. Along Bay Bengal, Sphyraena putnamae (Jordan and Seale, 1905) forms a significant fishery; however, no information exists globally with respect to its growth, mortality exploitation. This maiden study details population dynamics analysed from samples collected trawlnetters, gillnetters hooks lines al...

Abstract Reverse phase dispersive liquid- liquid microextraction (RP- DLLME) coupled with spectrophotometry is introduced for the detection of total phenol in the muscle tissue of fishes, such as Sphyraena genie, Otolithes ruber, Rastrelliger kangurta, Lutjanus johnii and Barbus Subquin Cunciatus. Phenols in fish tissues were extracted by ultrasonic bath and derivatization with 4- aminoant...

Few studies have examined seasonal diet variation and trophic relationships among fishes in shallow subtropical waters. We sampled consecutive wet and dry seasons within Biscayne Bay, Florida, USA, to examine seasonal diet and feeding habit variation in juvenile gray snapper Lutjanus griseus (GS), bluestriped grunt Haemulon sciurus (BSG), seabream Archosargus rhomboidalis (SB) and great barracu...

THE FISH FAMILIES Sphyraenidae, Mugilidae, and Atherinidae have been assigned to the percesocine fishes by all authors, and many would include only these (e.g., Berg, 1940: 368). Others have expanded the group in various ways (e.g., Boulenger, 1904: 636). Most commonly, however, such expansion has extended only to the family Polynemidae (e.g., Regan, 1912: 846) or, in recent years, to the polyn...
