Efecto de diferentes concentraciones de cal viva en el comportamiento de la calidad del agua en el cultivo de camarón OceanDocs
Ceballos, B.J.; Cabrera, J. E; Galindo, J..
When evaluating the behavior of the physical, chemical and biological variables of the water during the first 24 hours where different concentrations of lime were applied (50, 75 and 100 mg/L) to different salinities (15 and 30 ups) to the cultivation water, the analysis factorial showed the existence of an interaction of second order among the concentration of lime, the salinity and the time for the ammonium concentration, the pH and the one oxygenates dissolved, while for the temperature they registered interactions of first order for time x salinity, and time x concentration of alive lime. The quality of the cultivation water improved when diminishing the salinity and to increase the concentrations of lime. A preliminary analysis indicates...

Capturado el camarón tigre Penaeus monodon (Fabricius, 1798) en las costas de Cuba OceanDocs
Giménez Hurtado, E.; Pérez Jar, L.; Jaime Ceballos, B.; Fraga Castro, I.; Jiménez Cabrera, R.; Cabrera Vilaon, D.; Moreno Urquiza, A..
Se identificó una especie de camarón exótico como Penaeus monodon, camarón tigre gigante, mediante tres ejemplares hembras capturados en lagunas costeras de Tunas de Zaza, golfo de Ana María, Cuba. La talla varió entre 270 mm a 290 mm de longitud total (Lt), con un peso entre 140 g a 230 g. La presencia de la especie significa una adaptación a las aguas cubanas y constituye una perspectiva positiva para su cultivo.

Aislamiento, clonaje y caracterización biológica del ADN complementario de la Hormona Hiperglucemiante de Crustáceos de Litopenaeus schmitti (Decapoda: Penaeidae) OceanDocs
Yuliet Morera Darias.
El desarrollo alcanzado en la camaronicultura hasta el presente exige estudios cada vez más novedosos en vista a enfrentar nuevos retos. En este sentido resulta necesario el conocimiento de la estructura-función de los neuropéptidos de la familia de la Hormona Hiperglucemiante de Crustáceos (familia HHC). Ella juega un importante papel en el metabolismo y la fisiología influyendo directamente sobre la muda, el crecimiento, la reproducción, el metabolismo de la glucosa y lípidos, entre otras. La Hormona Hiperglucemiante de Crustáceos (HHC) es el componente mayoritario de la familia HHC y el único neuropéptido aislado y secuenciado hasta el presente. Ella es una hormona pleiotrópica y su función principal es regular el nivel de glucosa en la...

Alternativas tecnológicas para el procesamiento del camarón blanco (Litopenaeus schmitti) cultivado en Cuba. OceanDocs
Flores Gutiérrez, Eduardo R..
El cultivo del camarón se ha presentado como una alternativa de producción de este crustáceo ante los altos costos de las faenas de pesca provocados por los altos precios del combustible y los bajos rendimientos de las capturas ante el agotamiento del recurso. En el presente trabajo se presentan varias tecnologías de procesamiento del camarón susceptibles de ser aplicadas para su comercialización, así como una alternativa de organización del proceso de manipulación y procesamiento industrial que contempla una inversión para el procesamiento en las propias camaroneras, la cual conlleva una disminución de los costos de producción. Como resultados se obtuvieron las tecnologías para la producción de camarón entero, entero precocido, entero...

Cultivo a baja salinidad de postlarvas de Litopenaeus vannamei con diferentes relaciones de K+/ Na+ OceanDocs
Cabrera Machado, J. E.; Jaime Ceballos, B..
An experiment was designed totally randomized to study the influence of different rate of Na+/K+ (5, 30, 55, 70, 95 and 120). Massive mortality was presented to the sixth day of the treatments I and III (Na+/K+=5 and Na+/K+=120), to the seventh day the treatment V (Na+/K+=95) and to the eighth day of the treatment IV (Na+/K+=70). The treatments II and III (Na+/K+=30 and Na+/K+=55 respectively) they stayed in the time, when indicating a bigger tolerance of the postlarvae in these ranges of Na+/K+; however, the mortality of the treatment II were significantly bigger (p <0.01) that in the treatment III, in which 90-100% survival was observed. The results indicate a better physiologic answer of L. vannamei postlarvae to relationships Na+/K+...

Experimental studies on acclimatization of marine shrimps, Penaeus monodon and Metapenaeus monoceros to freshwater OceanDocs
Rathacharen, S.; Laxminarayana, A.; Venkatasami, O.; Codabaccus, B..
The adult shrimps, Penaeus monodon and Metapenaeus monoceros were induced to mature and spawn by eyestalk ablation. The larvae of both the species of shrimps were reared up to post larval stage on a diet of the phytoplankton, Chaetoceros calcitrans. The post larvae of M. monoceros were fed with artificial feeds only, whereas the post larvae of P. monodon were fed on small quantities of Artemia sp. in addition to artificial feed. After post larval stage, PL-20, the post-larvae were acclimatized to freshwater. Acclimatization was tried for different periods ranging between 2 and 20 days. The best survival rate was obtained for an acclimatization period of 5 days. Results obtained so far showed that the growth of P. monodon was significantly higher in...

Analysis of the marine shrimp culture production chain in Southern Brazil Anais da ABC (AABC)
Freitas,Rodrigo R.; Vinatea,Luis; A. Netto,Sérgio.
This study was elaborated to identify and describe the main links of the sea shrimp productive chain in the municipal district of Laguna, historically known as the main sea shrimp (Litopenaeus vannamei) production area in the State of Santa Catarina, Brazil. The study, held from April to July 2005, previously identified the local productive process through observation, interviews and bibliographical research. Afterwards, specific questionnaires were elaborated for each of the several segments connected to the local activity. A total of 90 interviews were conducted, intending to map out the procedures and functionality of the productive chain, from the necessary inputs for production to the moment of shrimp acquisition by final consumers. Results indicated...
