An Innovative Approach to Blood Collection from Fish

Abstract

Sally M Salaah

Tilapia is one of the most cultured fish in the world; it directly contributes to food security for many countries especially in Africa. Tilapia production is adversely affected by disease, infection, and pollutants. However, there are a few diagnostic tools available to evaluate fish health. Blood parameters are the key tool to investigate fish health. Yet the fish size has been a challenge to researchers and veterinary. The present technique has been developed to draw more blood rapidly from small tilapia fish (below 20gm), and big fish as well. The obtained volume of blood was proportional to the fish size. This technique sacrifices fish; it’s not suitable for repeated blood collection.
