The reproductive cycle of Larkinia grandis (Broderip and G.B. Sowerby I, 1829) from the NW Mexican Pacific was analyzed in relation to environmental variables, condition index (CI), and biochemical composition of different tissues. A total of 960 clams (80/month; 44.5–142.0 mm, shell height) were collected from the El Cohui estuary in the Navachiste ...

The relationship between the shell dimensions of pearl oysters. Pinctada mazatlanica (Hanley 1856) and Pteria sterna (Gould 1851). was studied to determine the possible change of form of the shell during growth. The intention was to determine the number, size and location of nuclei that could be implanted in oysters used for Mabe pearl production ...
