Description |
The oil sardine fishery at Karwar showed erratic fluctuations during the years of study, from an annual landing figure of 4.41 tonnes in 1964-65 to 250.06 tonnes in 1967-68. The average, based on the earlier 14 years' catch worked out to 91.21 tonnes. The three length frequency modes at 135-140, 160-165 and 185-190 mm have been interpreted to correspond to I, II and III age groups. The fish attains maturity at about 140 mm and the spawning season lasts from July-August to November-December. This is also supported by the trend of change in 'K' values. A good fishery season seems related to the temperature range of 27-29.5°C, lower salinity and a low phosphate content in the water. |
