Relationship between carcass weight and organ weight of cultured rainbow trout (Oncorhynchus mykiss)

Abstract: The relationship between carcass weight and organ weight of rainbow trout was investigated in Zreplicates usin a total of 300 trout of a Danish population. Within replicates, the trout were of a proximately $e same age. Absolute organ weights increased with increasing carcass weight while geir weights as a roportion of carcass weight decreased. Heart and liver weight were highly correlated with carcass weigit (.61-.81 and .86-.87, respectively), while the correlation between spleen and carcass weight was moder… Show more

“…The fish were killed by stunning after a blood sample was taken for investigation of the hematological values. The intestinal contents were removed and heart, liver, and spleen were weighed to study the relationships between carcass weight and organ weights (SCHMELZING and CLAUS 1990). The fins were cut off at their bases and the head detached immediately posterior to the gills.…”

“…In the culture of teleosts the same problems of antagonisms between carcass weight and susceptibility to stress, as well as between carcass weight and meat quality, can also occur. An earlier paper described the constitutional conditions (carcass weightorgan weights) in cultured rainbow trout (SCHMELZING and CLAUS 1990). This paper describes the relationships in cultured rainbow trout among carcass weight, acid-base values of the blood as an indicator for metabolic load susceptibility, parameters of meat quality, and body composition.…”
