- Abstract
Growth parameters and feeding indices, such as condition factor (CF), of the Iranian cichlid,Iranocichla hormuzensis, the only native cichlid of Iran, were investigated during the period between August 2008 and August 2009. The estimatedbvalue (the slope in length–weight equation) for males and females was 2.94, which is not significantly different from 3 that is indicative of isometric growth (p > 0.05). There was a significant difference (p < 0.05) between mean CFs of males and females. Males in the length group of 56–85 mm showed a higher CF than those in smallest (46–55 mm) and largest (86–100 mm) length groups. A total of 432 guts (217 of males and 195 of females) were investigated during the thirteen-month study period. The mean gut length, gut weight, relative gut length (RGL) and relative gut mass were significantly higher for males than females (p < 0.05). The RGL of males ranged between 1.12 and 8.24 (5.31 ± 1.26) and that of females between 0.58 and 10.43 (4.55 ± 1.53). AlthoughI. hormuzensisis an omnivorous fish, our findings suggest that by their feeding habits, males tend to be herbivores and females carnivores.
