(USSR) Reproduction of the Siberian Redside Sucker (Catostomus catostomus (Tilesius) in the Kolyma River rostau) LitVqpiTED TUCifiLialON FC.ir ieifOrrn& irn by Yu. A. - Shilin REVISU ultdeemoi The information on the biOlogy of the Siberian redside sucker in our literature (Berg, 1949; Kirillov, 1955; Novikov, 1966; Novikov and Streletskaya, 1966; Shilin, 1971) still does not throw sufficient light on all of its life processes. Besides, the Siberian redside sucker is one of the most abundant species in the Kolyma R. and, in our view, could be a promising subject for acclimation in the basins of the upper and middle courses of other rivers of the Soviet Union. This article is based on the results of observations carried out in 1966 - 1969, during which period 979 sex glands of the redside sucker were examined, histological study of the sex glands of 30 specimens of the fish was conducted, and experiments in the aritificial fertilization * Numbers in the right-hand margin are those of pages in the original. - Trans. 131* 2 of the roe were also completed. Kolyma redside sucker males first become sexually mature at the age of 6+, upon reaching a standard length of 28-30 cm, while the females reach sexual maturity at 7+ and a length of 30-32 cm (Shilin, 1971). ' The absolute fecundity of the Siberian redside sucker changes with age, and here an inverse relationship between fecundity and the age, length and weight of the fish (table 1) has been noted. The absolute fecundity of the redside sucker in the basin of the middle course of the Kolyma R. taken Table 1 Fecundity of redside suckers in the basin of the middle course of the Kolyma R.

In the lower reaches of the Kolyma, the absolute fecundity of the Siberian redside sucker varies between 29,800 and 59,800 eggs, for an average of 42,850. The fecundity of the Kolyma redside sucker approaches that of the American redside sucker, 132 3 which has from 17,525 to 60,307 eggs, for an average of 35,006 (Novikov, 1966). A study of histological sections from the sexual glands of maturing Siberian redside sucker females showed that the ovicells were in various phases of development. We noted ovicells in the slow, protoplasmic and trophoplasmic periods of growth. Asynchrony in the development of older generation oocytes were observed throughout the maturation period. Fig. 1 gives a picture of the asynchrony in the development of the oocytes in a female redside sucker ovary. The asynchrony in development of oocytes in intermittently-spawning fish provides grounds for supposing that the redside sucker spawns intermittently. David Behmer (1965) indicates that no residual roe was noted after spawning in the redside sucker of the Des Moines River. he states that some females spawn twice. At the same time, Our research in 1966-1969 during the spawning period revealed many females with partially spawned roe (up to 50%). Individuals with partly spawned roe were found in catches over a very brief period (for 8-10 days). All this confirms our supposition as to the intermittent nature of spawning in the Kolyma redside sucker. Thus, the results of our research disprove the idea which currently exists in ichthyology, to the effect that there are no intermittently-spawning fishes among the fish fauna of water bodies located in high latitudes. According to A. S. Novikov's data (1966), the redside sucker goes to spawn at the end of May - beginning of June, in those branches of the Kolyma R. that have a swift current and a sandy-pebbly bottom. Spawning takes place at a depth of 2-3 m. In the basin of the middle course of the Kolyma, we found males and females with flowing genital products in nid-June in streams of the first order, with pebbly bottoms of average P st c. 1.

This is the period when maximum water levels and currents of great swiftness were observed. It is essential to note that the spawning periods of the redside sucker in the middle part of the Kolyma are very short (15-20 days). This is determined by the peculiarity of the hydrological regime of this section of the river. Experiments in artificial fertilization of the roe showed that it does not adhere to the substrate. The fertilized eggs sank to the bottom and moved around freely there with the fluctuations of the water. 5 The presence in spawning period catches of 10-12 year-old females with genital products at the second stage of maturity provides grounds for assuming that part of the females skip a regular spawning. It is possible that this is connected with the migration of a population. LITERATURE 1. Berg, L. S. 1949. Countries. 4th ed., vol. II. Freshwater Fishes and those of Adjoining 2. Kirillov, F.

REPRODUCTION OF CHUKUCHANA— CATOSTOMUS CATOSTOMUS ROSTRATUS (TILESIUS) IN TFIE KOLYMA RIVER U. A. Shilin Summary . The Kolymskaya chuktichana males become at fist puberty at the age 6+ at the length AD 23-30 cm. and the females— at the age 7+ at the lentil 30-32 cm. The absolute fecundity fluctuates within the limits of 11 369-93 890 eggs. There is the retrospective dependence in the change of fecundity with the age. The microscopical studying of milts and ovaries points to the portional character of chukuchana spawning. In this connection the existing notion of the lack of the portional spawning of fishes at the high latitudes is placed under the doubt. * The All—Union Scientific Research Institute of Lake and River Fisheries. — Trans.
