Abstract

Golden spined loach belongs to the genus Cobitis family Cobitidae order Cypriniformes, it is a native fish fauna of Kazakhstan. Systematic position
spined loach, living on the territory of the Republic of Kazakhstan is not
defined. Currently, aboriginal fish fauna of our country feel the press from
alien species. In this connection, the aim of the research was to study the
morphology and biology golden spined loach found from the river Karashik
and river Shayan Syr Darya basin. Morphological studies were conducted on
33 and 4 plastic meristic characters. Results of the study golden spined loach
Syr Darya basin showed the following: spined length was – from 39.51 mm
to 64.32 mm, with an average of 53 mm. Weight of fish varied from 0,27g,
to 1, 34 g, on average 0.545 g. The results show a decrease in body length
and weight of the Aral golden spined loach. The studied fish presented sexually mature and juvenile stage individuals. The studied specimens from two
reservoirs golden spined loach different shape and location of spots on the
body. All specimens were dark patches of different shapes and sizes located
on the back, on the sides of the body at the base of the caudal fin on the
dorsal and caudal fins. The data show the diversity of the external morphology, color Aral golden spined loach from different bodies of water, which
indicates that an individual environmental variability of this species from the
Syr Darya basin in many morphological features
Key words: Aral golden spined loach, Syr darya basin, morphology,
biology, analysis, stage of development, the egg.
