Ponds are a main creation method to a large choice of freshwater fish species. each one species have particular and detailed nutrient wishes and winning pond fertilization is important to a winning aquaculture firm.  Aquaculture Pond Fertilization: affects of Nutrient enter on Production offers state of the art info for winning fertilization innovations for a large variety of pond-raised species.

Aquaculture Pond Fertilization makes an attempt to rectify the likely contradictory nutrient thoughts by means of truly defining the ambitions of particular sorts of aquaculture. Chapters are divided into 3 sections: the 1st reports uncomplicated thoughts in fertilization acceptable to all pond-based construction. the second one appears at particular nutrient administration ways. The 3rd and ultimate part of chapters seems to be in particular at key freshwater pond species starting from tilapia to perch and discusses particular fertilization wishes for the profitable rearing of those in-demand fish.

Looking throughout species with chapters contributed by way of leaders within the box Aquaculture Pond Fertilization offers succinct single-volume assurance of an oft-neglected, yet very important subject in aquaculture production.

5). The first move to increase fish production is increasing fish stocking density. This implies increasing levels of inputs (feeds, fertilizers, energy), management, and costs. Extensive systems require little management. Fish are lightly stocked and often no feeds are supplied, producing relatively low yields at low production costs. In semiintensive ponds, fish density is higher, and natural food webs can be enhanced applying fertilizers. Inorganic fertilizers promote the autotrophic planktonic path, while supplemented organic fertilizers (agriculture by-products, wastes, manures) and/or feeds are used directly by fish and also act as fertilizers of the heterotrophic and autotrophic food chains.

The sodium nitrate addition was to bring the 6-8-4 fertilizer up to the 8-8-4 level that was available during the first years of his research. 9 kg/ha P). 5 kg/ha P). 5 kg/ha P) applied as a single dose at the beginning of a 6-month growing season. Dobbins and Boyd (1976) compared phosphorus fertilization rates by varying phosphorus content of complete fertilizers, while keeping nitrogen and potassium constant. Ponds were stocked with small sunfish Lepomis spp. and fertilized 11 times during January to November.
