Abstract
The tench, predominantly lacustina fish, lives in stagnant or sluggish water-bodies with silt covered bottoms. The artificial propagation aimed to produce fish fries for re-stocking programme in natural ecosystems. The brooders comprised of 130 female and 80 male fish. The individuals weight of fishes ranged between 0.2 - 0.45 kg. The female and male fishes caught from wild stock, were separated and kept in two earthen ponds. The biotechnique of carp production were used for culture process. The eggs stripping conducted 8 times according to the ripeness of the brood stock. 60 femal spawners were injected by the Gonadotropic hormone from pituitary glands of carp fish to induce the brooders. The used dosage was between 3-8 mg per kg of body weight, applied in two doses. With only one treatment, 6-8 mg hormone were injected per kg of body weight. Water temprature were 20-24°C in June. Male spawners were treated only once with 3-4 mg of the hormone per kg of body weight. The experiment sho.....
