Abstract

Length-weight relationships and condition factor are of great relevance in fishery assessment studies. The relationship between length and weight is necessary for creating the yield equation and occasionally it may be helpful as a character to distinguish "small taxonomic entities" and the condition factor is useful in identifying fish biological changes. The present study describes selected biological parameters such as Morphometry, Length-Weight relationship and Condition factor of Horabagrus brachysoma, an endemic fish in the rivers of Western Ghats of India. A total of ninety four fish specimens were collected from Kodoor River, Puthuppally, Kottayam District, Kerala, India. The length-weight relationship of the collected species was determined and the results obtained showed that Horabagrus brachysoma found in Kodoor River has positive allometric growth. The b values ranged between 3.3 and 3.9; b value was higher in the case of males. The mean values of condition factors were found to be one in both the sexes and this shows a better condition of fishes in this aquatic system.

Conclusion

The results of the present investigation on morphometric study, length –weight relationship and condition factor revealed a good level of feeding and proper environmental condition and it also provide information for the management and maintenance of the biological equilibrium of their ecosystem. The results of the current investigation's morphometric study, length-weight relationship, and condition factor showed that the animals were receiving adequate nutrition and living in a suitable environment. They also provided information for managing and maintaining the biological equilibrium of their ecosystem.
