  The Reproduction Traits of Native Brown Trout (Salmo trutta macrostigma T., 1954), Turkey

  Kocabas, M.; Kayim, M.; Can, E.; Kutluyer, F.; Aksu, O.

  Some key aspects of the reproductive strategy of the brown trout Salmo trutta macrostigma (T., 1954) inhabiting Uzungol stream, Trabzon including spawning season, age at sexual maturity, fecundity and egg size have been studied between January 2009 to May 2010. The ages of the captured fish ranged from 2-8 years. Individuals were composed of 40.85% males and 37.80% females. The present investigation on the fecundity of S.t. macrostigma was carried out to estimate the average and range in the number of ova laid by individual female as well as to study the relationship of the fecundity with total length, total body weight. The mean value of absolute fecundity was 312.23 +/- 254.71 (SD) eggs/female. The regression between egg number and fish size (total length and weight) was statistically significant (p<0.05).

  Fecundity and Egg Size of Three Salmonid Species (Oncorhynchus mykiss, Salmo labrax, Salvelinus fontinalis) Cultured at the Same Farm Condition in North-Eastern, Turkey

  Serezli, Ramazan; Guzel, Senol; Kocabas, Mehmet

  In this study, fecundity and egg size of rainbow trout (Oncorhynchus mykiss), Black Sea trout (Salmo labrax) and brook trout (Salvelinus fontinalis) were examined. Two and six years old female fish reared in commercial fish farm were used and the female size, total and relative fecundity and egg size (mm) were determined for the broodstock fish of three tested species. The average weights of broodfish of rainbow trout, Black Sea trout and brook trout 1.357.27+/-406, 532+/-673.7 and 310.40+/-85.0 g, respectively. The total fecundity (number of eggs fish(-1)) was 2.809+/-791, 1.401+/-1374 and 723+/-320, the relative fecundity (number of eggs kg(-1) fish) was 2.180+/-676, 3.558+/-1307 and 2.571+/-1530 and the egg size (mm); 4.95+/-0.2, 4.51+/-0.67 and 4.49+/-0.21 were determined for rainbow trout, Black Sea trout and brook trout, respectively. A significant linear relationship was found total fecundity and the post-stripped fish weight of Black Sea trout (r = 0.96), but this relationship was low for the rainbow trout (r = 0.28) and brook trout (r = 0.17). A negative relationship was observed between the relative fecundity and brood size in rainbow trout (r = 0.57), Black Sea trout (r = 0.58) and brook trout (r = 0.54). A significant linear relationship was observed in rainbow trout (r = 0.63), Black Sea trout (r = 0.86) and brook trout (r = 0.41) (p<0.01).
