Acute toxicity of ammonia to blue tilapia, Oreochromis aureus in saline water

Evaluation of Blue Tilapia (Oreochromis aureus) for Duckweed (Lemna minor) Control in South Carolina's Private Waters

We evaluated the consumption of duckweed (Lemna minor, Linnaeus) by juvenile Blue Tilapia (Oreochromis aureus, Steindachner) through 48 hour indoor tank feeding trials. Feeding trials consisted of 5 tanks (4 treatment, 1 control). Tanks were stocked with 25 g of fresh duckweed at the initiation of each feeding trial. Designated treatment tanks were also stocked with 1 tilapia per tank. At the e...

Multivariate Analysis of Growth in Juvenile Tilapia Oreochromis aureus

A multiple regression analysis of growth in juvenile tilapia Oreochromis niloticus and 0. aureus (Cichlidac) is presented based on experiments conducted from 1984 to 1987 in recirculating systems a t the Tilapia Genetics Laboratory of the University College of Swansea. Wales, UK. One regression model was derived for 0. niloticus, one for 0. aureua and one for both species jointly. Overall fit, ...

Investigation of Acute Toxicity of Alpha-Cypermethrin on Adult Nile Tilapia (Oreochromis niloticus L.)

Alpha-cypermethrin, which is a synthetic pyrethroid pesticide and potential toxic pollutant, contaminating aquatic ecosystems was investigated in the present study for acute toxicity. Nile tilapia (Oreochromis niloticus) adults were selected for the bioassay experiments. The experiments were repeated three times and the 96-h LC50 value was determined for the adults. The static test method of ac...

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...
