Experimental Trials of the use of Pineapple juice in disticking Clarias gariepinus egg in indoor hatchery at Niger Delta Area. Nigeria
Abstract
Four treatments including three different concentrations of pineapple solution (1%, 3%, 5% and 0%) and the control (without juice) were used to test for elimination of egg stickiness of Clarias gariepinus. The control, fertilization and hatching rates were 74.5% ± 1.2 and 70.2% ± 1.1, respectively. The highest fertilization rate (89.3% ± 0.7) and hatching rate (86.6% ± 1.4) were found with treatment of 1% pineapple juice solution and was significantly different from those obtained from other treatments (P<0.05). Results of the trails showed that pineapple juice used for desticking Clarias gariepinus eggs reduced the time of egg handling.
