Grunion Leuresthes tenuis (Ayres), an atherine fish, were reared, from artificially fertilized eggs to 160 days posthatching, at temperatures from 18.0° to 25.4° C. The rearing was carried out in five 60 l rectangular containers and two hard moulded plastic pools holding 60 and 450 l. The growth rate was highly correlated with temperature at least up to metamorphosis. Thereafter, the effect of temperature on growth, within lethal limits, appeared to be lost or at least masked by other factors. At low densities, after metamorphosis, growth was proportional to the population density. Size and shape of the rearing containers also influenced the growth rate. |
