Abstract/ Executive Summary:

The fecundity and sex- ratio of B. gonionotus were studied. The fecundity of 99 gravid females varied from 18001 (total length 197 mill and body weight 72 g) to 42034 (total length 187 mm and body weight 159 g). The mean fecundity was 24959.23 ± 6961.48 (for mean total length 210.50± 17.26 mm, mean body weight 118.16±37.34g, mean ovary length 70.21±27.30 mm, mean ovary weight 13.66± 7.12 g and mean ovary breadth 15.4 ±2.79 mm). The relationship between fecundity (F) and other parameters such as total length, total body weight, ovary length, ovary weight and ovary breadth were studied. The fish was highly fecund and the number of eggs produced was more or less directly proportional to other different lengths.

Keywords: Fecundity, Barbodes gonionotus, Sex- ratio

Location: Fisheries Research Laboratory, Rajshahi University

Start Date: 00-00-1998

End Date: 00-00-1998

Program Area: Animal Health and Management

Commodity: Carp fish

Objectives:

To study the fecundity and sex- ratio of B. gonionotus.

Methodology:

A total of 274 specimens of B. gonionotus were collected at 'random from different places in Rajshahi city of which 130 females were identified. The gravid females were easily identified by their swollen abdomens. All collected specimens were preserved in 5% formalin. Total length and total body weight of the specimens were recorded. After dissection the gonads were taken out and then moisture was thoroughly wiped from the ovaries with blotting paper and weighed by a sensitive pan balance. The average total length and the average breadth of the ovaries were also recorded by a measuring scale and a divider. Gravimetric method was used for the estimation of fecundity.

The fecundity of 99 gravid females varied from 18001 (total length 197 mill and body weight 72 g) to 42034 (total length 187 mm and body weight 159 g). The mean fecundity was 24959.23 ± 6961.48 (for mean total length 210.50± 17.26 mm, mean body weight 118.16±37.34g, mean ovary length 70.21±27.30 mm, mean ovary weight 13.66± 7.12 g and mean ovary breadth 15.4 ±2.79 mm). The relationship between fecundity (F) and other parameters such as total length, total body weight, ovary length, ovary weight and ovary breadth were studied. The fish was highly fecund and the number of eggs produced was more or less directly proportional to other different lengths.
