Abstract

There have been few reports in Panama that informs about the risk that faces the genus Strombus and how can it be protected and cultivated, like it has been done in other countries that are working in the repopulation of various species of the Strombidae (Aranda and Suarez 1998, Brownell, W.N. 1977, Davis and Stoner 1994).\This project is very complex, in which morphology, physiology, and biochemical data is presented to study the relation between the data presented and the gonad development of gastropod Strombus raninusGmelin. Further more a comparison of the growth and physiology between the S. raninus and the S. gracilior is also made. In this project 82 individuals from the specie S. raninus were collected in the Coast of Colon, in the Caribbean Sea and 28 individuals of the S. gracilior were collected in Playa Chumical, in the Pacific Ocean. Thirty animals were random selected of S. raninus to determined the percentage of carbohydrates, lipids and proteins of different parts of the body, also parts of the gonads were treated on histological methods, dyed with hematoxiline - eosine and mounted in slides for observation. Another 20 individuals of each species of S. raninus and S. gracilior where submitted to physiological test (consumption of oxygen and ammonia excretion) every 15 days during a 3 months period. Next the same 20 animals of S. raninus where submitted to biochemical test and observation of the gonads in slides. In this project is expected that the results express a relation between the growth, physiology and biochemical changes within the state of the gonad maturity and determined the physiological differences between the species of both seas.
