Correlation between fat content and features of generative growth of arabesque greenling Pleurogrammus azonus
Objective: To determine the correlation between fat content and features of generative growth of
arabesque greenling Pleurogrammus azonus.
Methods: The samples were collected by bottom trawl during trawl surveys of research vessel
MRS-055 conducted by TINRO-Center in Peter the Great Bay (Sea of Japan). A total of 332
individuals of arabesque greenling were analyzed. Fat content was determined by the standard
method of extraction by sulfuric ether from the dry rest.
Results: The most part of deposit fat of arabesque greenling is concentrated in muscles and
hypodermis: 86.2%-97.0% (mean value 92.3%) of the total deposited fat mass. The liver fat
was 1.1%-7.7% (mean value 4.8%) and the internal fat was 0.9%-5.2% (mean value 2.8%) of the
total mass. Decreasing of the muscles fat was observed at sudden changes of qualitative and
quantitative characteristics of sexual products, and for immature fish the relation between
accumulation of fat in muscles and generative growth was not found.
Conclusions: Dynamics of fat in liver corresponds closely with the processes of generative
growth, and increasing of gonads weight causes decreasing of liver fat content, both for mature
and immature fish.
