Turtle bycatch and whale mortality in purse seines
are also possible in the WIO, but the probability of the latter is very low.
Both purse seines
and run-around gillnets are only feasible when fish are tightly schooled, which normally happens only in January, February, and March in the study area.
Faster-growing fish captured with gill nets had smaller scales than fish of a similar length caught with purse seines
Appendices provide data on the characteristics of fishes, names of fishes, tapering purse seines
, cutting web tapers, how to plan and cut nets, methods of net mending, handling and icing fresh halibut aboard vessels, sanitary operation of fish processing plants, operations involved in canning, and spoilage in canned fishery products.
Avoid: Tuna caught with gill nets, purse seines
with FADs, or most longline methods.
Sampling gear in the EPS study was restricted to fine-mesh purse seines
The fishery declined as market fishing for bluefins exploded and purse seines
and longlines began taking their toll.
Each harbor can handle the use of a limited number of purse seines
but Lebanon lacks strong biological data to regulate its use, meaning that nearly a dozen of the large nets can be deployed in a harbor only large enough for a few.
Greenpeace has long campaigned to stop the use of the method, which uses FADs to attract fish to huge nets called purse seines
Greenpeace has long campaigned to stop the use of the "destructive" method, which uses the floating devices to attract fish to huge nets called purse seines
During the initial decades of the snapper rig fishery, purse seines
for bait were scaled-down versions of the larger nets used in the menhaden reduction fishery (which often approach 1,200 ft long and 80-90 ft deep).
IUCN, however, notes that incidental catches of common bottlenose dolphins are known from throughout the species' range, in gillnets, driftnets, purse seines
, trawls, long- lines, and on hook- andline gear used in commercial and recreational fisheries.
