Resumen:
The shell height-body weight relationship of the black clam Chionista
fluctifraga cultivated in the intertidal of the southeastern Gulf of
California, was evaluated for the first time, to improve the knowledge
in determining its harvesting time. Clam seeds (n=900,000; 6.1 +/- 1.9
mm) were produced in the laboratory. The culture was divided into
pre-fattening in racks on the bottom (2 months) and fattening directly
in the bottom (16 months) from May 2018 to October 2019. Each month, 60
(n=1080) clams were randomly selected to stablish the morphometric
relationship between shell height (SH) and body weight (BW). The growth
rate (mm/d and g/d) was recorded. The SH-BW Interaction in both
cultivation phases showed positive allometry. SH in prefattening and
fattening registered a growth rate of 0.072 and 0.058 mm/d,
respectively. In fattening, the interaction BW-SH displayed a high
coefficient of determination (R-2=0.99). A final survival rate of 90%
was obtained. The results yielded the equations that describe the
relative growth of C. fluctifraga for the fattening stage. A harvesting
time after 10 months of fattening in the intertidal zone is stablished
to reach the commercial size (35 mm, SH).
