Title Present status of oil sardine fishery at Karwar
 
Creator Annigeri, G G
 
Subject Oil sardine
 
Description The average annual yield of traditional gears (Rarnpan and Yendi) from 1937 through 1982 for
16 years is 146.4 t. Consequent to introduction of purse seiners from 1976, tf)e average catch for
the 10 year period from 1976 through 1985 for oil sardine increased to 22^3 t at Karwar showing
nearly 15.5 times more yield than the former period. This paper discusses whether this new development
is a boon to the fishery or whether it has an adverse impact on the fishing stocks. For this purpose,
the average standing crop and average annual stock of oil sardine in the fishing grounds for a year
were estimated. An estimate on yield-per-recruit and the maximum sustainable yield (MSY) for varying
fishing intensities and Instantaneous natural mortalities was made to understand the extent of fishing
stress on the resource A closer scrutiny of all India catch data of oil sardine and mackerel from 1976 to
1980 when 35 to 400 numbers of purse seiners were introduced respectively, showed that the
premechanisation period (1970-75) accounted for better annual average catch than the purse seine
era (1976-1980) as the catch per day per purse seine declined. The optimum level of exploitation and
the adverse effects on the stocks if they are indiscriminately exploited without proper planning are
discussed in the paper.
