Estudio biométrico, estructura poblacional y habitat del camarón Penaeus vannamei, Boone en criaderos

Abstract

The present work is about biometry study, population structure and habitat Penaeus vannamei, Boone shrimp cultivated in ponds 939 shrimps were analised from March-July 1991 at a shrimp farm located in Hebano-Manabí port. The analysis demostrated that a strong difference exists between the male and female shrimp product of morphological diformis in this species. Also, the calculated correlation coeficient values were always near the unit indicated for us that the relations between the different averages were very narrow. The proportion of the sexes showed a clear predominance of the females over the males. The proportions being 60%/40% respectively. Aside from this, this population distribution remained steady during the period of the investigation. The study about the habitat demostrated that the physical parameters were kept in the following optimun rages: oxigen 4,4 ml/l, water temperature 26,86°C, salinity 24,20 ppt, pH 7,18 and turbidity 0,37 m.
