Pós-Larvas do camarão Litopenaeus vannamei, na fase de PL 9-10 e PL 25-26 foram aclimatadas à água doce (0,0 ‰), objetivando promover cultivos em regiões interioranas. Para isso, foram realizados dois experimentos conduzidos em aquários com capacidade útil de 44 litros e densidade de estocagem de 11,36 pós-larvas/L. No experimento 1, foram testadas diferentes concentrações de cal hidratada (0,018 g a 0,031 g) e 2 dietas, formuladas à base de ração comercial para camarão e biomassa de artêmia. No experimento 2, foram testadas 5 dietas com diferentes concentrações de biomassa de artêmia (0% a 100%), inseridas em rações de peixes e camarões. No final do processo de aclimatação, a sobrevivência das póslarvas variou de 40,44% a 98,04%. Concluiu-se que pós-larvas do Litopenaeus vannamei podem ser aclimatadas à água doce e que o aumento da concentração de cal e de artêmia na ração melhoraram significativamente (p<0,05) os parâmetros zootécnicos da espécie.
The coastal state of Espírito Santo is in the central region of Brazil, where biological productivity is considered low. The objective of this work is to present a current list of demersal, estuarine fish from northern Espírito Santo. This work is based on the compilation of data collected monthly using trawl nets. The ichthyofauna comprises 57 species, within 10 orders and 32 families. The family Sciaenidae has the largest number of species (8), followed by Carangidae (4) and Gerreidae (4). This coincides with what has been found for the Brazilian coast and for the coast of the South Atlantic. It is important to note that the total species richness in the estuaries of northern Espírito Santo is lower than other estuaries of the South West Atlantic coast. Most of the species are widely distributed in the Western Atlantic. Only a small part (14%) of the fauna of northern Espírito Santo was evaluated in regards to risk of extinction, but conservation should be prioritized in the area due to overexploitation of species
Este trabalho apresenta a relação peso-comprimento de 25 espécies de peixes. As coletas foram realizadas mensalmente de 2010 a 2011, utilizando redes de arrasto em estuários do rio Cricaré, Espírito Santo, Brasil.
