“…retardation of fish growth at higher densities, was observed by several earlier workers working with carps and other fish species (Lakshmanan et al. 1971; Vijayan and Leatherland 1988; Degani 1991; Zonneveld and Fadholi 1991; Bjoernsson 1994; Mohanty 1995; Hengsawat et al. 1997; Jena et al.…”

Experiments were conducted in eight ponds of 0.08 ha each for a period of 6 months to evaluate the production performance combinations of Indian major carps and exotic carps at varied stocking densities and species. The four different treatments evaluated were stocking densities of 5000 and 10 000 fingerlings/ha with three Indian major carps (catla, rohu, mrigal) and combination of three Indian major carps with three exotic carp species (silver carp, grass carp and common carp) in replicate ponds. The mean net production levels recorded in different treatments were 1791 kg/ha, 2385 kg/ha, 2532 kg/ha and 3472 kg/ha in 6 months in treatments with three species combinations at 5000/ha, six species at 5000/ha, three species at 10 000/ha and six species at 10 000/ha, respectively. Correspondingly, the mean growth, survival and feed conversion ratios recorded in four treatments were 432 g, 84.7% and 1.49; 567 g, 86.2% and 1.47; 318 g, 82.1% and 1.69; and 444 g, 80.4% and 1.67, respectively.

“…The higher growth rate of C. catla (surface feeder), C. carpio and C. mrigala (bottom feeders) were attributed to their effective utilization of ecological niches and the presence of a rich detrital food web that was maintained through periodic manuring, liming and fertilization. The comparatively slow growth and lower survival in T 2 was probably due to the fact that, under crowded conditions, fish suffer from stress due to aggressive feeding interactions and eat less, resulting in growth retardation (Zonneveld and Fadholi 1991;Bjoernsson 1994) and low survival (Procarione et al 1999). The higher yield and species-specific higher individual growth performance in T 1 than T 2 was probably due to the periodic phased harvesting that minimized the competition for food and space among the cultured species.…”

This study was carried out to study the impact of phased harvesting on the population structure, feed intake pattern and growth performance of Macrobrachium rosenbergii in polyculture with carps in a deepwater rice-fish system. There were two experimental conditions-rice-fish culture with phased harvesting (T 1 ) and rice-fish culture without phased harvesting (T 2 )-and a control, which consisted of rice monoculture without fish (T 3 ). In the T 1 trial, 61% of the population had a mean body weight (MBW) \20 g 120 days after stocking (DAS), which fell significantly to 7.3% at 210 DAS. However, in the T 2 trial, 62% of the population had a MBW\20 g at 120 DAS, which only fell to 23.7% at 210 DAS. Similarly, at 210 DAS, 12.5% of the population attained a MBW [80 g in the T 1 trial, while none of the population reached a MBW [80 g in the T 2 trial. The removal of fast-growing individuals in T 1 improved the prospects of other smaller individuals to achieve their individual growth potential. This step also disrupted the continuation of the socially induced differential growth rates, resulting in a wide variation in size within the population over time. The matrix of dietary overlap(s) of cultured species revealed that the degree of food preference was more similar between Cyprinus carpio and M. rosenbergii (0.9), while it overlapped poorly between Catla catla and M. rosenbergii (0.42). This high similarity index between bottom dwellers is evidence of the strong possibility that these bottom dweller compete for food. Natural and supplemental feed together with phased harvesting boosted the production of freshwater prawns (550 kg ha -1 ) in the T 1 trial, while a 11.3% reduction in production was recorded in the T 2 trial.

In aquaculture, controls of size (length and weight) and production of fish are two important tasks to meet the market demands, and increasing the stocking density is a way of dealing with the prohlem of land shortage. In this study, tilapia fry were stocked at the densities of 0,1, 0,2, 0.4, 0,8, 1.6 and 3,2 fry 1~' for an experimental period of 10 weeks. The size, size variation, percentage sun'ival and production were found to he significantly affected hy stocking density, hut not for condition factor. The simple linear regression model, after the logarithmic transformation, was appropriate for the relationship hetween size and experimental period. The percentage survivals at al! stocking densities were high ( > 95%). especially at the stocking density of 0,4 fry 1"' and less (100%). At the higher densities, percentage survival and experimental periods were anti-logistically related. At the end of the experiment, there was a negative relationship hetween the logarithms of size and the logarithms of stocking density, but a positive relationship between the logarithms of production and the logarithms of stocking density.
