Abstract:

Skeletal deformities cause severe economic losses in the aquaculture industry due to the reduced market value of the affected fish. The banded cichlid (Heros severus) is an ornamental cichlid native to the Amazon region. In the summer 2011 during clinical investigation on 750 severum of 5 ornamental fish farms in Karaj and Tehran, Iran, a two-year-old severum having deformity in dorsal and anal  fins  was referred to the radiology section of Veterinary Teaching Hospital. Standard, high quality radiographs were taken and studied. Deformities in vertebrates, plural ribs, neural spines and hemal spines were detected. Kyphosis and Lordosis was observed in V14 to V18. The scoliosis in both parts was left and right sided and in first part was detectable in V10 to V13 and in second in V24 to V29. Neural spines of V14 to V17 and hemal spines of V16 to V22 were deformed. This case history showed that parents of this fish were offspring’s of the same fish and implies that inbreeding of brood stock may cause such deformities.

Meristic variations and skeletal deformities in natural population of mahseer fish, Tor putitora (Hamilton, 1822)

Skeletal deformities seriously relegate the biological performance of fish. The frequency of occurrence of different types of meristic variations and skeletal deformities were shown in population of Mahseer fish, Tor putitora, in two main reservoirs; Korang stream, Islamabad and Dhobi Ghat stream, Hassan Abdal. Total of ninety-five fishes were caught randomly, forty-five from the unpolluted Kor...

Evaluating the effect of dietary soybean oil on growth performances of juvenile severum (Heros severus)

Evaluating the effect of dietary soybean oil (S.O) on growth performances of juvenile ornamental fish Severum (Heros severus) was the main objective of this study. To achieve this objective, 462 fish were considered which were divided into 7 test groups including 6 groups of fishes (with an initial average weight of 0.6 ± 0.05 g and length of 2.3±0.35 cm) fed diets containing 6 levels of S.O (D...
