Relationship between Fish Body Weight, Cultured Fish Density, Dissoｌved Oxygen Consumption and Fish Body Length of Fish Culture

Abstract

The mean fish body length, the fish body weight and cultured fish number per unit volume of the pen are estimated from the practical fish culture data of yellowtail, sea bream and so on. Depending on these data, the relationship between the body length and body weight and numbers of cultured fish per unit volume of the pen are clarified. Moreover the dissolved oxygen consumption by fish per unit volume of the pen are discussed.
