A Review of Length-Weight Relationships of Fishes from Greek Marine Waters
K.I. Stergiou and D.K. Moutopoulos

This paper presents 649 length-weight relationships gathered from literature pertaining to 83 fish species, belonging to 34 families, throughout Greek marine waters. The value of the slope b ranged from 1.667 for Cepola macrophthalma to 3.707 for Mullus barbatus. The mean value of b was 2.989 (SD=0.339) and did not differ significantly from 3 (t-test, p<0.05). The median value of b was 3.058 and 50% of the b values ranged between 2.900 and 3.186.

Growth Studies of Sciaenids from Mumbai Waters using the Bhattacharya Method
S.K. Chakraborty

Length frequency data of six sciaenids (Johnius macrorhynus, J. vogleri, Otolithes cuvieri, J. sina, Pennahia macrophthalamus, J. dussumieri) were collected from shrimp trawlers at New Ferry Wharf and Sassoon Docks landing centers off Greater Mumbai. Growth parameters of these species were analyzed via modal progression analysis using Bhattacharya’s method. Natural mortality (M) was estimated using Cushing’s formula. Comparison of growth parameters was done using the φindex. The growth parameters obtained were compared with the results of earlier growth studies which used other techniques. This study concludes that the growth parameters obtained are consistent with earlier estimates.
