Lipolytic response of adipose tissue and metabolic adaptations to long periods of fasting in red tilapia (Oreochromis sp., Teleostei: Cichlidae).

Estimation of ammonia excretion rates during a period of red tilapia, Oreochromis sp. Culture, considering biomass increase in a water recirculating system

A completely randomized experimental design was conducted to estimate ammonia excretion rate by red tilapia (Oreochromis sp.) during different stages of its growth in recirculating water system units typically designed to meet the experiment purposes. Eight weight groups each containing 75individuals of 20, 30, 40, 60, 80, 120, 180 and 200g average weight were considered as treatments in duplic...

Roles of natural zeolite (clinoptiolite) as a bed medium on growth and body composition of red tilap (Oreochromis sp.) and lettuce (Lactuca sativa var longifolia) seedlings in a pisciponic system

Natural zeolite was used as a bed medium for plantation of lettuce seedlings and its effects on growth and chemical composition of red tilapia and lettuce were investigated in a pisciponic system. The place of study was the Aquatic Resources Technology Laboratory, Faculty of Agriculture, at the University Putra Malaysia, in 2002. The mean individual weight and biomass of fish in the treatment w...

Acclimation responses of gill ionocytes of red tilapia (Oreochromis mossambicus × O. niloticus) to water salinity and alkalinity

To understand the acclimation strategies of red tilapia to different environments, this study aimed to evaluate different responses of red tilapia (O. mossambicus × O. niloticus) to salinity (10-30‰), alkalinity (1-3 gL-1 NaHCO3) and salinity and alkalinity (10/1-30/3 ‰/gL-1NaHCO3) environments. Localization, type, size, and numeration of gill ionocytes were investigated on the sa...
