Optimum dietary protein levels and protein to energy ratios on growth and survival of juveniles spotted Babylon (Babylonia areolata Link) under the recirculating seawater conditions

A feeding experiment of three dietary protein levels (35, 40 and 45%) and three dietary energy levels (3.8, 4.0 and 4.2 kcal g-1 diet) factorial design with four replicates  was conducted to determine the proper dietary protein and energy levels for the growth and survival of the juveniles spotted babylon Babylonia areolataunder the recirculating seawater conditions. Snails with initial body weight...

Zooplankton-based assessment of the trophic state of a tropical forest river

In this study, we explored the usefulness of zooplankton as a tool for assessing the trophic status of a Nigerian forest river. The river was sampled monthly and investigated for water physico-chemistry and zooplankton community structure using basic statistical measurement of diversity indices to characterize the zooplankton fauna. The trophic status of the river evaluated from the physico-chemical parameters indicates...
