The inter-relationship of various body measurements with regard to length in Clarias gariepinus, reared in cemented ponds was initiated from March-September 2021 by using 200 individuals (110 males and 90 females). These specimens of experimental fish ranged from 14.4 to 37.0 cm in length and from 44.7 to 985 g in weight and were obtained from the stock marinated in the cemented ponds of the University of Sindh, Jamshoro. At 5cm intervals, samples of fish were separated into groups. Fish body dimensions, including fish head length, fin measurements and the diameter of fish eyes and mouth gape were examined. No significant difference between male and female was noted; though, there was a small variation in the percentages of lengths such as standard and anal fin, which were greater in females (85.0 and 15.3 percent, respectively) than in males (83.2 and 10.6 percent, respectively). The length of the head, the width, the pectoral fin, the pelvic fin, and the dorsal fin were all bigger in males (90.76, 70.31, 11.28, 11.97, 4.95, and 4.51%) than in females (90.68, 25.64, 62.71, 10.73, 8.8, 35, and 3.3%), but the dorsal fin was smaller in both sexes. eye diameter was shown to be greater in females (3.88%) than in males (2.08). The dorsal, pectoral, pelvic, anal, and caudal rays of five distinct fins of both sexes were counted (male and female). The meristic counts of male and female Clarias gariepinus from cement ponds did not differ significantly (P>0.05). Finally, it was concluded from the inter-relationship of various body measurements and meristic analysis that there was a single homogenous population of Clarias gariepinus, available in ponds. The culture of this species may produce a significant role in generating revenue in the country. [ABSTRACT FROM AUTHOR]

This study was focused on fish health assessment in relation to sex and season via haematological variations and serum biochemical constituents of Labeo rohita from Kotri Barrage near Jamshoro, Sindh, Pakistan. Fish samples (100 specimens for each sex) were collected during two seasons i.e., summer: March to May, 2017 and winter: November, 2017 to January, 2018. Haematological characteristics of the fish specimens were considered season and sex wise separately. Results showed that erythrocytes (2.09 × 106 to 2.26 × 106), leucocytes (164.90 × 103 to145.55 × 103) and haemoglobin (10.34 g/100 ml to 7.06 g/100 ml) concentration were significantly higher in male fish during summer and winter than that of female. In female fish, erythrocyte sedimentation rate (ESR) in summer and winter season was found higher (7.3 mm/h to 2.56 mm/h). Thrombocytes, neutrophils, lymphocytes, eosinophil and monocytes did not show any significant difference in their counts of male and female fish during summer and winter season. Important serum constituents like protein, cholesterol and glucose were also assessed and it was reported that serum glucose was found more in male than female fish, while in male protein and cholesterol were high in female in summer. In winter season, female fish showed low level of cholesterol, though protein and glucose remained high. Based on the serum biochemical constituent data, it was concluded that male L. rohita were healthier than the female fish in terms of blood parameters. [ABSTRACT FROM AUTHOR]
