Food ingestion and assimilation by Hyale media (Dana, 1853) (Crustacea - Amphipoda)

Abstracts

The feeding of Hyale media was analysed under laboratory conditions in winter and summer temperatures. The results showed that assimilation rates increased following food ingestion rates and decreased when egestion rates increased. In winter temperatures no significant differences were found in the assimilation rates among developmental stages and sexes. In summer temperatures assimilation rates for ovigerous and non-ovigerous females were higher than those found for adult and young males. Although not statistically analysed, mean assimilation efficiencies were highest among ovigerous females and adult males, in summer. The quantitative and qualitative variations found in the assimilation efficiency and rates were explained by the differential effect of temperature on the specific growth rate and in the physiological conditions of each growth stage concerned.

RESUMO

No presente estudo foram analisados em laboratório, sob temperaturas de inverno e verão, aspectos quantitativos da alimentação de Hyale media (Crustacea-Amphipoda), utilizando-se o método gravimetría), aliado ao conteúdo de carbono dos itens alimentares oferecidos.

Nos experimentos com temperatura de inverno não foi encontrado diferença significativa nas taxas de assimilação entre os diferentes estádios de desenvolvimento e sexo. Naqueles com temperatura de verão as taxas de assimilação para fêmeas ovígera e não ovígera foram maiores que aquelas encontradas para machos adulto e jovem.

As variações encontradas nas taxa e eficiência de assimilação foram explicadas pelo efeito diferencial da temperatura sobre a taxa de crescimento específico e condições fisiológicas de cada estádio de desenvolvimento.
