Correlation between length-weight and age in Barbus sharpeyi and Barbus grypus broodstocks in artificial propagation
This study was carried out to identify proper broodstock of Barbus sharpeyi and Barbus grypus using working fecundity indices. For Barbus sharpeyi three female groups were chosen based on previous experiences that included treatment 1: 650±300g, 1±0.5 years, (T.L) 40.68±2.7cm, treatment 2: 135...

| description | This study was carried out to identify proper broodstock of Barbus sharpeyi and Barbus
grypus using working fecundity indices. For Barbus sharpeyi three female groups were
chosen based on previous experiences that included treatment 1: 650±300g, 1±0.5 years,
(T.L) 40.68±2.7cm, treatment 2: 1350±350g, 2.5±0.5 years, (T.L) 47.92±4.63cm and
treatment 3: 2200±400g, 4±0.4 years, and (T.L) 59.62±3.56cm. The same male broodstock
(700±80g) and 2 year old fish were used for all treatments. For Barbus grypus three female
groups were chosen using previous experiences that included treatment 1: 2212.5±780g,
2.5±0.5 years, (T.L) 62.68±6.7cm, treatment 2: 4518±780g, 4±1 years (T.L) 79.12±4.36cm
and treatment 3: 7712.5±171g, 7.7±1.3 years and (T.L) 92.62±3.13cm. The same male
broodstock (1400±100g) and 2 year old fish were used for all treatments. Female broodstock
of the two species were injected 3mg/kg of PG hormone two times at an interval of 10 hours
and males were injected 2mg/kg. The maximum working fecundity was seen in treatment 2
for Barbus sharpeyi (33000±1450) and Barbus grypus and (13000.37±4651.57). Functional
fecundity were calculated for Barbus sharpeyi in all treatments which was significantly
different between treatment 2 and other treatments for the two species. After this stage, the
working fecundity was decreased in treatments. We conclude that treatment 2 is the best for
selection of broodstocks in the two fish species. |
