Influência da temperatura e da salinidade na sobrevivência e crescimento de larvas da ostra perlífera Pteria hirundo
Palavras-chave:
larvicultura, Pteriidae, fatores abióticosResumo
Os fatores que mais afetam as taxas de crescimento e sobrevivência de larvas de bivalves são a temperatura e a salinidade. Uma espécie de ostra perlífera, Pteria hirundo (Linnaeus, 1758), apresenta bom potencial de cultivo no sul do Brasil. Neste estudo foram avaliadas diferentes combinações de temperatura (23, 26 e 29°C) e salinidade (25, 30 e 35 ups) na sobrevivência e crescimento para otimizar a produção de larvas dessa espécie em laboratório, como forma de implementar a produção de sementes. O delineamento experimental utilizado foi bifatorial inteiramente casualizado, com três repetições. Um total de 25 mil larvas por unidade experimental (U.E.) foi colocado em recipientes retangulares de polipropileno (10 L), com 5 L de água em cada salinidade estudada. Estes foram mantidos em tanques com 250 L de água providos de aquecedor e termostato, regulados de acordo com as temperaturas experimentais, em sistema de banho-maria. Na temperatura mais baixa (23°C), a sobrevivência foi maior e o crescimento das larvas foi menor, sendo este favorecido nas temperaturas mais altas (26 e 29°C) (P<0,05). A salinidade não teve influência significativa no crescimento final das larvas, entretanto, a salinidade mais baixa (25 ups) resultou em menor sobrevivência larval. A interação da menor temperatura (23°C) com a maior salinidade (35 ups) (P<0,05) resultou em melhores taxas de sobrevivência e crescimento, sendo essa combinação a recomendada para a larvicultura de P. hirundo nas condições avaliadas.
