MUSCLE FIBRE DISTRIBUTION IN WILD AND REARED SEA BASS, <i>DICENTRARCHUS LABRAX</i> (LINNAEUS, 1758) OF COMMERCIAL SIZE: STUDY BY MUSCLE BLOCKS
Abstract
Muscle cellularity was studied in wild and reared sea bass, Dicentrarchus labrax L., at commercial size (≅350 g), in different muscle blocks from transversal section of the axial musculature at both craneal and caudal levels of the miotome. Muscle parameters quantified were white muscle fibre diameter and white muscle fibre density. Results show different muscle cellularity among the studied blocks. Such differences are made evident when inner blocks (b and c) are compared with apical zones (a and d) and so, muscle fibre size was smaller on the apical zones. However, this tendency is reversed at caudal level from reared specimens. Also, at caudal level, the muscle fibre size on the block c presented differences between both wild and reared specimens.Downloads
