This study estimated the abundance gradient of fishes in waters surrounding a marine protected area (MPA) and used this information as evidence spillover from MPA. Fish landing data were collected trap fishermen over 12-month period Blue Bay Marine Park on west coast Mauritius Western Indian Ocean. Two indicators used: catch per trap, number fish trap. A Generalised Linear Model was to standard...

Abstract Plastic materials were evaluated in the guts of fish Shatt Al Arab river from four stations Al-Najebia, Al-Dakier, Al-Ashar and Al-Bradieyha at middle section. Seventeen species caught seasonally during study period January 2022 to December 2022. Projectina microscope was used measure lengths plastic particles for first time fish, their ranged between 0.04 mm 1.75mm. Different identifi...

Research objective was to identify the specific features of distribution microelements (zink, manganese, lead, cadmium) in organs and tissues black-backed shad Alosa kessleri (Grimm, 1887) Dolginsky herring braschnikowii (Borodin, 1904) caught Caspian Sea. Accumulated fish concentrations exceeding maximum permissible limits, heavy metals pose a danger human health. Sampling carried out by stand...

Abstract Length-weight relationships (LWR) were determined for Brotula barbata , Dentex angolensis macrophthalmus Neomerinthe folgori and Scorpaena stephanica using individual fish records collected between July 2002 January 2003, during a pilot project of experimental fishing over the shelf off Guinea Bissau. Fishes caught by commercial vessels bottom longline, measured defrost total length (t...

Recreational fisheries are an important element of contemporary fisheries. Detailed information about the motivation and opinions anglers regarding catch-and-release fishing in post-communist countries, such as Poland, has not been widely available to date. The aim this study was fill gap. We obtained 936 survey questionnaires completed by from throughout Poland. mean annual catch a Polish angl...

Objectives: The main objective of the study was to collect and rear unmarketable, small sized S.javus which is mostly rejected by traditional fisherman. During fishing activities, under ranging in sizes from 25 40 kg (< 30-40 % total catch/day) being captured. Due very low marketable value these fishes (<250 g) get rejected. Therefore, we utilized this as an economically viable option for...

—Many fishery biologists that are interested in documenting fish habitat and following the movements and behavior of fishes use acoustic tags. Because over 700 fish species naturally produce lowfrequency, species-specific sounds, these can be used as natural acoustic tags. Passive acoustic approaches (monitoring sound-producing fishes with hydrophones) show great promise for gathering data in a...
