Rearing of major carp spawn at high stocking density under air lift water circulation system

The present studies are aimed to achieve a high survival rate of carp spawn to fry stage under Air Lift Water Circulation system at high stocking density. Three experiments using Labeo rohita and Cirrhinus mrigala were conducted in one cement tank of 50 sq.m. area. The results showed a survival rate ranging from 90.5 to 95.2% at stocking density of 20 to 25 million/ha. By this technique it is possible to rear high number of spawn in limited area with high rate of survival up to fry stage.

Mass breeding of silver carp in a cement cistern with crude H.C.G.

The paper presents a resume on experiments carried on mass breeding of the silver carp Hypophthalmichthys molitrix in a cement cistern through administration of crude human chorionic gonadotropin. The experiments proves that human chorionic gonadotropin (H.C.G.) can be used for mass breeding of the fish in simple enclosures, with facilities of some input and output of water and a dose of 5 mg/kg and 18 mg/kg of body weight, for males and females respectively are required for the purpose. Observations were made by using pituitary glands in similar way. For successful breeding of about 80 kg female together, the expenditure towards cost of pituitary gland and H.C.G. are respectively 275 and 117 Rs.

Report on two types of leptocephalus-eel from Vellar Estuary (Bay of Bengal)

Two types of leptocephalus-eel, identified as ophichthyid larva and Muraenesox cinereus, collected from the Vellar estuary, India, are described. M. cinereus larvae are common in the estuary during November-January whereas ophichthyid larvae are very rare, collected on one occasion (January) only.

Maturity and spawning of Otolithus argenteus (Cuvier) from Karwar waters

The present paper deals in the maturity stages, ova diameter and spawning season, of Otolithus argenteus from Karwar waters. The seven stages of maturity were determined based on the macroscopic appearance and microscopic study of intra ovarian eggs. The average size at first maturity was found to be 160 mm. The diameter of ova varies from 0.01 to 0.82 mm. with various modes, indicating the nature and the frequency of spawning.

Histochemical studies on the olfactory epithelium of some hillstream teleosts

Living specimens of Barilius bendelisis, Crossocheilus latius latius, Torputitora, Glyptothorax pectinopterus and Pseudecheneis sulcatus were collected from the streams and rivers of Garhwal Himalaya. Histochemical localization of carbohydrates (1:2 glycol groups, glycogen, B-metachromasia and acid mucopolysaccharides), proteins and protein bound NH sub(2) group, bound lipids and the enzymes (acid and alkaline phosphatases) in the olfactory epithelium were studied. The receptor, supporting basal and mucous cells show varying degrees of distinction and distribution of these substances. The enzymes are present on the surface of the epithelium, sensory hairs and the boundaries of mucous cells only.
