Over 50% of the total bigeye tuna (BET) landed in the Western Central Pacific Ocean is caught incidentally in the purse seine fishery and sold for canning at prices less than US$2/kg. The remainder is landed in longline fisheries directed at BET and sold as fresh or frozen tuna at prices greater than US$10/kg. The combined fishing mortality by all gears will soon reduce the BET biomass in the P...

The natural mortality (M) and purse-seine catchability and selectivity were estimated for Trachurus novaezelandiae, Richardson, 1843 (yellowtail scad)-a small inshore pelagic species harvested off south-eastern Australia. Hazard functions were applied to two decades of data describing catches (mostly stable at a mean +- SE of 315 +- 14 t p.a.) and effort (declining from a maximum of 2289 to 642...

length weight relationships of vimba vimba persa were studied. for this purpose 174 fish samples were collected by gill nets, beach seine and purse seine from march through june 2008 at two guilan fisheries catch stations of guilan located in anzali- kiyashahr regions. samples were immediately transferred to the laboratory of fish biology at university of guilan for further analyses. length, we...

The reason for large number gears because this considered to be quite effective use and also availability potential support it carrying out its operation. using methods aimed at schools fish. purpose study was determine specifications...

In Côte d'Ivoire, fishing in Grand-Lahou locality provides 20% of national artisanal catches. From August 2016 to February 2017, units and the ichthyological composition their gears were characterised on Lahou-Kpanda site. One unit using beach seine, eleven purse seines seven gillnets involved. Twenty-two fish species have been identified. Twenty-one them caught by seines, seine six gillnet...

Although overfishing has been recognized as responsible for the decline of major fish stocks, it has been less easy to demonstrate its indirect and detrimental effects on marine mammals, particularly dolphins. Competition with fisheries for the same food resources has been hypothesized to have led to the decline of several species of dolphins, including the endangered Mediterranean short-beaked...

Tuna fisheries catch over three million tonnes of skipjack tuna (Katsuwonus pelamis) each year, the majority of which come from purse-seine vessels targeting fish associated with man-made fish aggregating devices (FADs). A significant challenge for fisheries management is to maximize the efficiency of skipjack tuna catches whilst minimizing the bycatch of small and immature bigeye (Thunnus obes...

Penurunan produksi perikanan purse seine di Laut Jawa memberikan peluang diciptakannya alat tangkap dengan spesifikasi yang lebih kecil. Alat tersebut disebut Mini Purse Seine (MPS) hasil tangkapan dominan adalah ikan layang benggol. Ketersediaan informasi terbaru karakteristik MPS perlu dilakukan. Penelitian dilakukan sentra Rembang yaitu TPI Tasik Agung dan Sarang pada tahun 2019-2021. Kapal ...
