| Abstract: | Both mackerel mean biomass and mean fishing effort in Buenos Aires (Argentina) shelf during the period 1990-91/1994-95 were estimated. Those values were 85,792 t and 42,051 minutes, respectively. However, the best economic profit from the fishery (about $15,390,036)($1=U$S1) was estimated to take place at 28,000 minutes. It was observed a waste in fishing effort of the commercial fleet related with sea surface temperatures of 19°C or more. Moreover, adult mackerel find better trophic conditions on the continental shelf (depth 50m), while larvae originated from massive spawning in late November-early December, i.e., during the main fishing season, find their optimum at lower depths. Mackerel shoals enter and leave fishing grounds in a counterclockwise way pushed by waters from the median shelf. A fishing strategy according with sea surface temperature is proposed to lead the commercial fleet. |
