4T American plaice (Hippoglossoides platessoides)

27 Jul 2005

In 1995, cod bycatches caused most of the American plaice in 4T were exploited mainly by longlines 14 closures affecting vessels less than 65 feet in the in the 1930s, but by the 1960s most landings were made by 4T plaice fishery. [...] At least recorded the length composition of landed plaice half of the annual landings of 4T plaice were obtained as catches, resulting in two closures of the plaice fishery bycatch of the Atlantic cod fishery until 1993, the year that the cod fishery was closed. [...] Landings of 4T plaice totaled 2310 t in 1995, similar to the 1994 landings of 2419 t. Annual landings since Surveys: The average catch of plaice in the survey 1965 have averaged 7647 t, with a maximum in 1976 was 176 per standard tow in 1995, the lowest level (11193 t) and a minimum in 1993 (1403 t). [...] The 0 number of vessels directing for plaice increased for seines from 49 vessels in 1994 to 53 vessels in 1995, while a strong increase was noted in the number of Abundance index of 4T American plaice based on trawlers directing for plaice: 23 vessels in 1994, 41 research surveys. [...] Since plaice bycatch in the cod fishery has ceased and there has been no marked Distribution maps and analyses of the aerial extent of increase in plaice-directed effort, plaice fishing plaice in surveys indicate that plaice of all age classes mortality is probably lower since 1993 than in the tend to occupy the same sectors in periods of high period before closure of the cod fishery.
