  • Title: Seasonal changes in the testes of a hill stream teleost, Garra gotyla (Gray).
    Author: Shrestha TK, Khanna SS.
    Journal: Acta Anat (Basel); 1978; 100(2):210-20. PubMed ID: 619498.
    Abstract:
    The cephalic, middle and posterior regions of the testes in Garra gotyla are identical in structure and function. The spermatogenetic activity starts in the month of October reaching its peak in April and May. Spawning takes place in June and July followed by a brief resting period. Spermiation appears to be intermittent. Six stages of spermatogenesis have been described. New crop of germ cells appears to arise from the resting spermatogonia. Both the interstitial and the lobule boundary cells were observed. The gonosomatic index shows correlatation between the rise in water temperature and the volume of the testes.
