Biodiversité et dynamique des peuplements ichtyiques de la mangrove de Guaratuba, Brésil
Provedor de dados: 5
Autores: Chaves, P; Bouchereau, Jl.
The Bay of Guaratuba, whose area is approximately 45 km(2), is a basin, situated to the south of Brazil (25 degrees 52' S; 48 degrees 39' W) and connected to the Atlantic ocean. In its northern part, a region of mangrove is found, under the influence of seasonal fluvial contributions, dominated by Laguncularia racemosa. The depth exceeds 6 m in some places. According to the period of the year, salinity varies between 3 and 37, and temperature between 15 and 28 degrees C. Several of the present fish species are exploited by commercial and recreational fisheries. This work describes characteristics of the fish populations occupying this mangrove, and temporal and spatial evolution of populations of the main species from available data on their biology....

Use of mangrove habitat for reproductive activity by the fish assemblage in the Guaratuba Bay, Brazil
Provedor de dados: 5
Autores: Chaves, P; Bouchereau, Jl.
The role played by a southwestern Atlantic mangrove in the breeding activity of estuarine fishes was evaluated. This fish assemblage represented 85 % of the total catches of the experimental fishery surveyed between 1993 and 1997. To evaluate the maturation and spawning processes, qualitative (macroscopic stages of maturation) and quantitative (gonadosomatic index) attributes were considered which were combined in a reproductive activity index. Four types of occupation were found in the mangrove, according to the reproductive patterns presented by each species. It was estimated that the Guaratuba mangrove is used as a spawning site - either regularly or occasionally - by about 40 % of the species, that make up 41 % to 46 % of the total abundance of this...
