Effect 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 کاملStocking Density and Supplemental Feeding
Pond carrying capacity is largely determined by management practices. Earlier work on semiintensive culture of tilapia using manure or inorganic fertilizers indicated that carrying capacity might reach 2,000 to 3,000 kg/ha (Diana et al. 1991a, b; KnudHansen et al. 1991). As stocking density is increased in fertilized ponds, carrying capacity remains largely the same and density-dependent growth...
متن کاملBioenergetic modelling of effects of fertilization, stocking density, and spawning on growth of the Nile tilapia, Oreochromis niloticus (L.)
A bioenergetic growth model was developed to examine the integrated effects of fertilization, stocking density, and spawning on the growth of tiiapia, Oreochromis niloticus (L.), in pond aquaculture. The analyses showed that growth rates increase with higher levels of organic ferlilization up to 5(HJkg/ha/week. Growth rates increased with added food rations in ponds, reaching a maximum growth o...
متن کاملFeather Pecking of Laying Hens in Different Stocking Density and Type of Cage
Both stocking rate and housing systems are main factors influencing the occurrence of feather pecking in laying hens raised in conventional cage system. This study examines the effects of different type of cage and stock density on feather pecking behaviour in hens. Total of 216 Hisex Brown hens at 16 weeks of age were randomly selected and put into 2 types of battery cages: conventional cages ...
متن کاملEffect of stocking density and salinity on the growth and survival of golden Anabas fry
Stocking density and salinity influence on the growth and survival of golden Anabas fry were studied. Experiments were carried out at Hatchery Unit, Institute of Bioscience, Universiti Putra Malaysia, Serdang Selangor, Malaysia. Growth parameters were measured once a month. While survival was monitored daily throughout the experimental period. Water quality such as temperature, dissolved oxygen...
