Effect of morphological development on the locomotion function of Nile tilapia, Oreochromis niluticus during early ontogeny
This study was conducted to investigate the hydrodynamic parameters and how morphological changes affect them in Oreochromis niloticus at the National Museum of Natural History-Paris in the winter of 2020. To record fish movement, a high-speed camera (1000 fps) with a macro lens was used. The fish trajectory was taken by calculating coordinates of a center point between the two eyes and kinemat...
متن کاملEffect of Stocking Density on Monosex Nile Tilapia Growth during Pond Culture in India
Stocking density is considered one of the important factors affecting fish growth. But, information related to impact of stocking density on growth performance of monosex tilapia population under the ecological conditions of Gangetic plains in West Bengal, India is limited. The aim of our study was to compare the growth potential of monosex tilapia at various stocking densities and to determine...
متن کاملEffect of Feeding Frequency on Growth Rate, Body Composition and Gastric Evacuation of Juvenile GIFT Strain of Nile Tilapia (Oreochromis niloticus)
The specific objectives of this study were to determine the optimum feeding frequency in juvenile GIFT (Genetically Improved Farmed Tilapia) strain of Nile tilapia (Oreochromis niloticus), for growth rate, body composition, and gastric evacuation, as well as to investigate the passage of a single meal through the stomach in order to establish gastric evacuation rate. Six treatment groups of juv...
متن کاملDifferences between Male and Female Growth and Sexual Maturation in Tilapia (oreochromis Mossambicus)
In tilapia, growth during critical periods of the life cycle varies at different ages of development and is influenced by sexual maturation. The mechanisms controlling gametogenesis and how growth affects this process are poorly understood. This study indicates that tilapia exhibit a sexually dimorphic growth pattern in which males grow faster and bigger than females. During critical periods of...
متن کاملAn experimental analysis of the effects of dietary lipid sources and feeding ration on the reproductive performance, egg and larval quality of Nile tilapia, Oreochromis niloticus (L.)
This study investigates the effects of dietary lipid sources on the growth and reproductive performance of Nile tilapia over three consecutive spawnings. Fish were reared using three experimental diets, with the goal of replacing dietary fish oil with palm oil. Three experimental diets and a commercial trout diet was used as the control. The effect of dietary lipid on the growth performance, ...
