Biotechnology tools are an important for improving the fish production

Aquaculture needs innovative biotechnological interventions to overcome challenges in terms of rapid disease diagnosis, production of disease-free or high health brood stock for seed production, suitable preventive and therapeutic measures to control disease outbreaks. Increased in growth rate of world fish’s population demand. Aquaculture, therefore, remains the last hope for providing enough fish for the world, but with limited land and water space. Aquaculture biotechnology, therefore, has come to have a key role to play as it can make a great contribution to improving aquaculture yields. These techniques are potentially faster and more sensitive than traditional culture, serology and histology methods. The DNA-based techniques like Polymerase Chain Reaction (PCR), Real-time-PCR (qPCR), multiplex PCR, DNA probe-based in situ hybridization and microarray etc. there have a wide scope of applications in fish disease diagnosis. The application of biotechnology to various production systems does not come without its negative impacts but even still, the merits far outweigh the associated concerns because the techniques are constantly being developed thereby reducing the negative impacts thereof. Therefore, there is need to adopt biotechnological practices if the world is to stand any chance of achieving food security.
