Abstract:
Striostrea prismatica (Gray, 1825) represents one of the most popular and artisanal fisheries in the rocky coast, but now cultivation of stone oyster in a call channel for shrimp is a new method to calculate their growth, condition index and survival. A total of 1 500 juveniles were seeded with a length of 19.1 ± 3.2 mm, width of 16.2 ± 3.19 mm, height of 3.97 ± 1.36 mm and 1.0 ± 0.54 g weight. They were placed in 70-60 organisms Nestier type baskets, seeds were collected from the oyster shells which were discarded by fishermen. Temperature was the most important variable, combined with salinity and food availability in seasons, coupled with low concentrations of seston which had a negative correlation with growth and consistent with the increase in the condition index and rates high growth. Survival rate was 73.03%. The model parameters von Bertalanffy growth are L∞ = 142.63; k = 0.0489 and t0 = -2.198. At the end, height and average weight was 73.53 ± 15.38 mm and 31.56 ± 17.17 g, which although is less than the minimum catch size proposed in NOM 90 mm, the results show that the fattening of juvenile oyster is appropriate for the fishery resource, applicable and effective for strategy management.
