The common thresher shark (Alopias vulpinus) is a secondary target species of the California drift gillnet fishery (CA-DGN) and supports a growing recreational fishery in California waters. This study used archival tags to examine the movement patterns and habitat preferences of common threshers of the size range captured in the CA-DGN (>120 cm fork length). Depth and temperature-logging archiv...

Gillnetting is one of the most practiced fishing methods adopted in the South of Brazil and has been increasingly expanding over the last years. This paper presents the characterization of the activity and discusses its management, in accordance to results from the discussions on the development of regulations on net fisheries in the South Coast Marine Protected Area (APAMLS) in the state of Sã...

We estimated bias-corrected mean fork lengths of gillnet-caught chum salmon using a size selectivity estimate of the gillnet to test how the bias correction affects the estimated temporal pattern of chum salmon body size, during 1971–1994 and 1994–2007. Results showed bias-corrected mean fork lengths were smaller than uncorrected means. Therefore, when examining ontogenetic changes in fish size...

In this study, experimental fishing trials were performed to quantitatively evaluate and compare the performance of trammel nets, tie-down gillnets, single gillnets used for catching blackfin flounder. A total eight cruises at depths 100–140 m in waters near Yangyang, Gangwon-do, Korea. Fisheries laws Korea currently restrict use nets due concerns about overfishing bycatch. Tie-down have a supp...

Pada sektor perikanan, Labuhan Maringgai merupakan salah satu daerah penghasil rajungan di Indoneisa. Alat tangkap yang digunakan untuk menangkap adalah jaring insang dasar atau bottom gillnet. Hanging ratio berbeda pada pengoperasian alat gillnet dianggap berpengaruh terhadap hasil tangkapan. Penelitian ini bertujuan mengetahui perbedaan respon tangkapan (Portunus pelagicus) penggunaan hanging...

Fisheries often exert selective pressures through elevated mortality on a nonrandom component of exploited stocks. Selective removal of individuals will alter the composition of a given population, with potential consequences for its size structure, stability and evolution. Gillnets are known to harvest fish according to size. It is not known, however, whether delayed mortality due to disentang...
