"Weed and predators compete with aqua crop (fish) for space, dissolved oxygen, food micronutrients and physical factors etc. These resulted into poor growth of fish, it means less production. Predators not only injurious to fishes on above ways but also directly prey upon them. Wound caused by predator to prey is found to be prone to infections. Prey-predators relationship and aquaculture management practices have also been discussed. On the other hand, importance of soil, water and manuring in piscicultures are discussed. Pollutants/pollution causes a great loss to fisheries filtration technology and remedial measures are focused in this book to get better yield." (jacket)
