The experiment was conducted in two earthen ponds to investigate the body composition, and fatty acid profile of carps along with growth performance by using rice polish as fish feed with urea and ammonium nitrate fertilization of pond. Silver carp (Hypophthalmichthys molitrix), Rohu (Labeo rohita) and Mori (Cirrhinus mrigala) were stocked in the ratio of 1:2:1 respectively with total number of...

Little is known about the growth performance of sex-reversed, all male Oreochromis niloticus under different traditional and non-traditional culture methods practiced in India. In this study, 17"methyltestosterone treated monosex tilapia was cultured in concrete tank, flow-through system, cage, pen and earthen pond. Similar feeding regime and stocking density of fish were maintained for all the...

An experiment was conducted in nine 200-m2 earthen ponds at the Asian Institute of Technology (AIT), Thailand from 17 July 2003 to 3 March 2004 (230 days). The objectives of the study were to assess the feasibility of co-culture of lotus and hybrid catfish in intensively fed ponds, to assess nutrient recovery from feed waste by lotus plants, to assess pond mud characteristics after lotus-fish c...

Increased production of fish through intense culture practices often leads to not only stress and disease problems but also alteration in water quality. The organic wastes and bad water quality influence the growth of pathogenic microorganisms. Bioremediation using pond probiotics is considered a promising way to circumvent these problems. For this study, three earthen fish ponds stocked with P...

As a first step in assessing the viability of periphyton-based fish production in South Asian pond aquaculture systems, the effects of artificial substrates on development of periphyton and on water quality were evaluated. Earthen ponds (10 × 7.5 m) were provided with an artificial substrate constructed from poles of either bamboo, kanchi or hizol tree branches (1.0 m artificial substrate per m...

In Southeastern Brazil tilapia culture is conducted in extensive and semi-intensive flow-through earthen ponds, being water availability and flow management different in the rainy and dry seasons. In this region lettuce wastes are a potential cheap input for tilapia culture. This study examined the ecological processes developing during the rainy and dry seasons in three extensive flow-through ...

The New Caledonia blue shrimp Litopenaeus stylirostris is commercially produced under semiintensive rearing conditions. The size of the farming earthen ponds (5–10 ha) and the subsequent production constraints make it difficult to use them as experimental units for random experiments. Moreover, since every pond has its own characteristics, ponds' effects cannot be ruled out, thus making it hard...
