Title

COMPARISON OF SOME BIOLOGICAL PARAMETERS BETWEEN GRASS CARP AND FEMALE GRASS CARP X MALE BIGHEAD CARP HYBRID

Pages

  1-10

Abstract

 Grass carp and two years old female GRASS CARP x male bighead carp hybrids were reared under polyculture condition in combination with silver carp, bighead carp and common carp for a period of 4 months (Jul-Nov). Physicochemical parameters of pond water as well as indexes of GROWTH, GONAD development and carcass proximate analysis were compared between GRASS CARP and hybrid fishes. Final results showed that condition factor of hybrid and GRASS CARP had decreasing rate (means 1.07 and 1.32, respectively). Percentages of final weight gain were obtained 37.8 in hybrid and 37.7 in GRASS CARP (no significant differences). Specific GROWTH rate in both species were 0.25 %; daily GROWTH rate found 3.44 g. and 0.44 g. in GRASS CARP and hybrid, respectively.Histological study or GONAD development in both species showed the ovaries of GRASS CARP had a normal GROWTH and consist of primary oocyte, but hybrid ovary GROWTH remained in primary oogonial stage. In male GRASS CARP, testis had a proliferated spermatogonia stage in contrast with primary spermatocyte stage in hybrid testis.Proximate analysis of carcass of both species showed no significant differences in protein, ash, lipid and moisture content of meat (p>0.05). Study of erythrocytes volume and area on investigated samples confirm that, they were totally TRIPLOID fish.
