S. Planes et al., ANALYSIS OF CONDITION AND SWIMMING PERFORMANCE IN JUVENILES OF WHITE SEA BREAM, DIPLODUS-VULGARIS, Journal of the Marine Biological Association of the United Kingdom, 77(3), 1997, pp. 913-916
A pilot study was conducted to follow condition and swimming performan
ces over two months using three samples of 50 juveniles of white sea b
ream, Diplodus vulgaris. The initial result indicated that the weight-
length relationship followed the model; W=5.2x10(-3)L(3.49). According
to this relationship, condition indices were estimated for each indiv
idual as the observed weight related to the computed weight. Measures
of swimming velocities realized in an artificial flume show variations
through time with an increase and decrease directly correlated to con
dition indices. Maximum speed of an individual was measured at 12.3 cm
s(-1). Analysis of environmental conditions indicated that the decrea
se of condition index and swimming performances was related to bad wea
ther which induced turbid water in juvenile habitats.
