| description | The life history traits and gonad development of an endemic cyprinid fish, the spotted barb, Capoeta mandica
(Bianco & Banarescu 1982), from southern Iran was investigated by regular monthly collections from February
2006 through January 2007 and on the basis of microscopic and macroscopic analyses. No information on the
spawning characteristics of the fish are available to date. A total of 335 specimens were captured using
electrofishing including 253 males and 102 females, resulting in 2.5:1 (male: female) sex ratio, which is significantly
different from the expected ratio. The commonly known five standard maturation stages were determined based
on the size, shape and weight of the gonads, degree of occupation of the body cavity, presence or absence of ripe
oocytes, or milt, diameter of the oocytes in the ovary, and histological observations. These stages were correlated
to the reproductive indices. The ovum diameters ranged from 0.04 to 1.31 mm, with the highest mean value in
May. The condition factor of male and female specimens was the highest in April. The female GSI increased from
March to May, peaking in the middle of spring and decreased significantly in June. Based on the gonad maturation
stages, gonadosomatic index (GSI), modified GSI, mean egg diameter, condition factor (K) and Dobriyal index (DI),
it was concluded that the spotted barb spawns during May and June. The provided data, contribute baseline data
towards management ecology and conservation of this endemic fish species. |
