The length-weight relationship in Sardinella sirm Wal from the Andaman Sea

Preliminary details are given of studies conducted regarding the length-weight relationship of Sardinella sirm from the Andaman Sea, a species of economic importance in the area. Results show that this species grows in proportion to length, weight and girth; the group of fish studied was composed of the same population and did not reveal any subspecies of sub-variety.

Length-weight relationship of Upeneus sulphureus (Cuvier) collected off Maharashtra coast

The length-weight relationship of Upeneus sulphureus was studied on the basis of 125 females and 103 males, collected during the 27th cruise of research vessel M.V. Saraswati in the month of September, 1984. The correlation coefficient was found significant at 5% and 1% level respectively for male and female. In both the sexes, the regression co-efficient was found higher than three. Analysis of covariance was also carried out for the F test and F distribution.

A note on morphometric and length-weight relationship of Upeneus moluccensis (Bleeker) off Veraval coast

Upeneus moluccensis were collected from the catches of bottom fish trawl of "M. V. Saraswati" off Veraval coast in the area lat. 20 degree 26 N and long. 70 degree 35 E. The fish were analysed for length-weight relationship and morphometric characters. The fishes were found to vary from 116 to 161 mm in length and 20.0 to 50.0 g in weight. The exponent value and correlation coefficient for length-weight relationship was found to be 2.73 and 0.991 respectively.
