Evaluating catches of salmonids taken by gillnets
Journal of Fish Biology, 1995Data from 10 185 gillnetted brown trout (Salmo trutta L.) and 5777 Arctic charr [Salvelinus alpinus (L.)] were analysed. Relative to mesh size, the most efficiently caught fish length (the modal length) was somewhat larger with floated nets than with smaller nets placed on the bottom.

Variations in Catchability of Fishes with Color of Gillnets
Transactions of the American Fisheries Society, 1973Abstract Gillnets of nine colors were compared with white nylon to determine effects of each color on catch rates of numbers and weights of 15 species of fishes in Elephant Butte Lake. Data were analyzed with mixed-model analysis of variance. Significantly different catch rates were compared, as fractions of unity (ratios), with rates in white nets ...

Mitigating unaccounted fishing mortality from gillnets and traps
Fish and Fisheries, 2013AbstractGillnets and traps often are considered to have fewer holistic environmental impacts than active fishing gears. However, in addition to the targeted catches, gillnets and traps still cause unwanted mortalities due to (i) discarding, (ii) ghost fishing of derelict gear, (iii) depredation, (iv) escaping or dropping out of gear, (v) habitat damage,

MODIFYING GILLNETS TO REDUCE ENTANGLEMENT OF CETACEANS
Marine Mammal Science, 1991AbstractTo reduce the number of cetaceans caught incidentally in gillnets, two forms of acoustic modifications have previously been proposed. These modifications seek to make gillnets more obvious to cetaceans so they can avoid them, and include making gillnets more reflective to cetacean sonar and placing active sound emitters in the nets.

The lobster fishery with gillnets in the Eastern Adriatic
Rapports et procès verbaux des réunions - Commission internationale pour lNULLexploration scientifique de la mer Méditerranée, 2001Lobster fishery in the Eastern Adriatic should be performed with pots and lobster gillnets, but other gillnets and trammel nets are also used. Influence of gillnets, with inadequate mesh size, on lobster has been evaluated according to length frequency of caught lobsters, percentage of immature specimens, sex ratio and length-weight relationship ...

Incidental Catch of Cetaceans with Salmon Gillnet
Journal of the Fisheries Research Board of Canada, 1975Using data on number of cetaceans caught per 1000 "tans" (= approximately 50 m) of salmon drift gillnet, incidental catch rates by salmon research vessels of the Japanese Fisheries Agency averaged 0.476. The maximum was 1.42. The average ranged between 0.37 and 0.65 from 1962 to 1971, indicating negligible effect on porpoise populations. These figures

Tiger Shark Bycatch in Gillnets
Tiger Sharks has a global distribution. Fishing practices have become more widespread and careless. Fishermen are abandoning gillnets resulting in bycatch of many marine animals including Tiger Sharks resulting in a decline in their population. The types of gear used is a primary factor in the number of shark bycatch numbers (Oliver, et.al 2015).openaire +1 more source
Hake fishing with gillnets in the Eastern Adriatic
2002European hake is one of the most important fish in the Eastern Adriatic. It has been caught by trawls, gillnets, longlines and other fishing gear. Research for the evaluation of the gillnets on hake population has been conducted in the Velebit channel. Total of 3881 specimens of hake and other fish and marine organisms have been caught during research ...
