| [gonadic cycle of the american oyster crassostrea virginica (lamellibranchia: ostreidae) in mecoacán, tabasco, méxico]. | the american oyster crassostrea virginica is exploited along gulf of mexico. this resource represents a job source and incomes for fishermen. in mexico the production is supported by tabasco state, the first producer. however, the mexican landings of this bivalve had been dropped about 40% last ten years. by 1999, tabasco presents a unique ban season fishery of oysters. this season was based in evaluation of gonadal development by visual observations of color and texture, larvae and seeds abunda ... | 2003 | 15264561 |
| [growth and survival of seeds of the oyster crassostrea virginica in a shrimp farm in yucatán, méxico]. | a lot of 1600 seeds of american oyster crassostrea virginica from the coastal lagoon la redonda, tabasco, mexico was cultured in main drainage channel (s1), a secondary drainage channel (s2), the floodgate of a white shrimp pennaeus vannamei pond (s3) and the marine water supply pond (s4). the seeds, with a total height and initial humid weight of 31.67 +/- 3.43 mm and 4.29 +/- 1.32 g, respectively, were cultured in suspended nestier oyster boxes at 575 org/m2. biological and environmental param ... | 2000 | 15266788 |
