ECOSYSTEM OF THALASSIA-TESTIDINUM BEDS IN GUADELOUPE (FRENCH-ANTILLES) - RELATIONS BETWEEN FISH RECRUITMENT AND HABITAT

The bottom of tropical lagoons is frequently covered with seagrass bed s which are inhabited by fish communities, essentially juveniles. Occu pation and use of these nurseries depend on population abundance and r eception capacity of the environment. In consequences, a permanent ren ewal of population is observed, which is variable in time and space, a nd follows general patterns previously described in Guadeloupe.
