Heteroclarias Spp fingerlings/post fingerlings are products of a cross between male Heterobranchus longifilis and female Clarias gariepinus.
Heterobranchus spp has a growth rate twice as fast as that of Clarias gariepinus while the latter survive in poorly
oxygenated water. Hybridization between these two clariid catfishes thus produces offsprings that possess a combination of these desirable qualities.
The objective of fish farming is to obtain the maximum increase in weight (biomass) of the fish/unit area of volume/unit with a specific level of management practice. These require the knowledge of fish growth, carrying capacity, nutrition, yield, and water quality parameters.
Features of Heteroclarias spp fingerlings
- Heteroclarias spp is very rugged and disease resistant, and they consume less feed when compared to Clarias species.
- They attain bigger sizes than Clarias spp, and they weigh much higher at harvest.
- They thrive well on a wide range of plant protein based fish feeds.
- Longer post-harvest survival thus will be preferable to buyers.
- Improved taste due to its white flesh.
