An on-station trial was conducted to evaluate the effect of stocking density of freshwater prawn and addition of different levels of tilapia on production in carbon/nitrogen (C/N) controlled periphyton based system. The experiment had a 2x3 factorial design, in which two levels of prawn stocking den...

This study investigated the effects of substrates and supplemental feeding on growth and production of tilapia (Oreochromis niloticus) and freshwater prawn (Macrobrachium rosenbergii) in a polyculture system. On actual farms, four treatments were evaluated in triplicate: substrate plus feed (herein ...

The present research investigated the optimum surface area of periphyton substrate in earthen ponds stocked with a pre-optimized density and ratio of the Indian major carps, catla (Catla catla), rohu (Labeo rohita) and kalbaush (Labeo calbasu) to support enhanced fish production. Four treatments in ...

This experiment was carried out to evaluate the effect of an organophosphate pesticide, sumithion on water and sediment quality and benthic invertebrates in aquaculture ponds for 120 days. Three treatments were tried in duplicate: no sumithion (control), weekly application of 1.0 mg/L sumithion (Low...

The potential of periphyton-based aquaculture in southern Asia is under investigation in an extensive research program. This paper is a further analysis of data from two experiments carried out in that framework, to explore periphyton-environment relationships in the absence of fish grazing pressure...

The effects of periphyton grown on bamboo substrate, on growth and production of Nile tilapia, Oreochromis niloticus (Genetically Improved Farmed Tilapia strain) in monoculture and polyculture with the freshwater prawn (Macrobrachium rosenbergii) were studied and economically evaluated. The experime...

A bioeconomic study of periphyton-based aquaculture in Bangladesh was carried out through comparison of on-farm and on-station trials. Five treatments, three on-farm and two on-station, each with four replications, were tried in a completely randomized design: on-farm control without substrate or fe...

The present research investigated the effect of stocking density on pond (75 m2, depth 1.2 m) production of Nile tilapia (Oreochromis niloticus) and freshwater prawn (Macrobrachium rosenbergii) stocked at a fixed 3:1 tilapia:prawn ratio. Three stocking densities were tried in triplicate: 20 000 ha−1...

<title>Abstract</title> A brief history of fish polyculture system and pond polyculture (in particular) as an age-old practice in Asia is provided. A list of suitable fish species for polyculture is also given. The benefits of traditional polyculture can also be enjoyed in periphyton-based aquacultu...
