In terms of quantity produced, Catla catla is the sixth most important finfish aquaculture species produced globally in 2015. It is primarily grown in South Asia, often on a small scale in polyculture with other species. In spite of its economic importance, in a number of countries, including Bangladesh, the quality of catla seed produced in hatcheries has historically suffered from high levels of inbreeding, uncontrolled interspecific hybridisation and negative selection.
The objective of this study was to evaluate the effects of fishmeal (FM) replacement with corn protein concentrate (CPC) on growth performance, nutrient utilization, gut morphology and skin coloration of red hybrid tilapia, Oreochromis sp.
The nutritious pond concept is a novel approach that enables the pond itself to contribute significantly to the diet of the farmed fish/shrimp. Our research shows that feeding the pond by balancing the carbon-to-nitrogen ratio can increase the contribution of naturally occurring food in the diets of the cultured animals, thus enhancing reliance and reducing production costs and environmental impact.
