“…Some workers assign its origin to nuclear activity (Hubbard, 1894;Wheelar, 1924;Subramaniun, and Aiyar 1935;Sathyanasen. 1959) and others believe it to be cytoplasmic in origin (Narain, 1951;Chaudhry, 1952;Bara 1960;Nayyar, 1964).…”

The ovarian cycle and spawning season of Ophiocephalus punctatus from Chapra, BIHAR, a subtropical area, is described. The oocyte shows six well differentiated stages of maturation and the fish has a prolonged spawning season extending from May to August. The spawning tends to be bimodal in character. The stages iii the formation of the yolk nucleus of Balbiani are described and the probable origin of this cytoplasmic inclusion is discussed.

“…As regard the origin of yolk nucleus, there are two schools of thought one school states its origin from the c y toplasm (Chaudhry, 1952;and Nayyar, 1964), while second school describes its origin from the nucleus (Wheeler, 1924, Sathyanesan, 1959 In C. fasciatus the yolk nucleus appears adjacent to the nuclear membrane in young oocytes which g r a dually becomes distinct and finally moves to the peripheral zone of the ooplasm where it disintegrates and disappears. According to Wheeler (1924), yolk nucleus does not participa tes in the formation of yolk.…”

“…Several workers studied the yolk nucleus in many fishes, but there is no agreement on them regarding the origin and function of this structure (Narain, 1937, Chopra, 1961, Nayyar, 1964, Wheeler, 1924, Chaudhary, 1952, Bara, 1960.…”

Histological studies on the gonads of Clariasmagur were undertaken to describe the maturity stages and understand the mode of gonad development. Based on the histological studies, six stages of oocytes development were identified. The seasonal variations in the average weight of the ovary, along with the ova diameter and Gonadosomatic Index suggests that the spawning period of this fish is from last part of June to the first part of September and the fish attains its maturity for spawning after the commencement of good rain. A systematic account of Clariasmagur isprovided.
