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...

effect of globacid® acidifier in different stocking densities on performance and blood metabolites was examined using 576 one-day broiler chickens ross 308 in a completely randomized design with 6 treatments and four replications for each treatment through a (3 × 2) factorial arrangement with three levels of stocking densities (14, 16 and 18 chicks per square meter) and two levels of globacid® ...

In this study, the effects of oxygen supplementation in different stocking densities of rainbow trout (Oncorhynchus mykiss) on the specific growth rates (SGR), feed conversion ratios (FCR) and survival rates were investigated in a commercial-scale culture system. High density cultures were maintained in a total of nine (12 m3) flow-through systems supplemented with O2. Initial stocking rates fo...

three stocking densities (20, 40, and 60 sheep/ha) were applied in four stocking periods (0, 2, 4, and 6 weeks) on a medicago truncatula cv. paraggio pasture. treatments were arranged in a split plot system and compared through a completely randomised block design with four replications.grazing period had a significant effect (p

An experiment on the polyculture of carps with high valued small indigenous fish species (SIS) pabda (Ompok pabda) and gulsha (Mystus cavasius) was carried out in six months culture period to evaluate the production performance of carp with small indigenous fish pabda (Ompok pabda) and gulsha (Mystus cavasius) in the on-farm condition. Three stocking densities of pabda and gulsha were tested, k...

With the target of increasing the shrimp (Penaeus monodon) production through farm development and improved grow out management, an experiment was conducted with three different stocking densities viz. 5/m (T1), 7/m (T2) and 9/m (T3). Results of the experiment revealed that, among the water quality parameters, values of dissolved oxygen and transparency were lower in the higher stocking densiti...

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...

Two experiments were conducted to study the effects of stocking density on growth performance, carcass yield, and foot pad lesions of White Pekin ducks from hatch to 14 d of age (experiment 1) and from 14 to 42 d of age (experiment 2), respectively. All ducks were reared in raised plastic wire-floor pens with a pen size of 30 m(2), and males and females were mixed at a ratio of 1:1 in each pen ...
