Effects of Tiny Moss Bryum capillare Meal on Growth Parameter, Haematology, Histology and Carcass Quality of Clarias gariepinus (Burchell) Juveniles

Abstract

This research determines the effects of Tiny Moss Bryum capillare meal, on growth parameter, Haematology, Histology and Carcass Quality of Clarias gariepinus (Burchell) Juveniles. The study was conducted for fifty six (n=56) days, under a completely randomized design. Tiny Moss Bryum capillare was included in to the experiment at level of 0, 2, 3, 4, 5% The final body weight and the daily weight gain increase as the Tiny Moss (Bryum capillare) inclusion increased among the individual treatment. The results of the feed conversion ratio were significantly (p <0.05) different among the groups, such that T1 and T2 had the best FCR followed by T5 and T6 which had similar values but the T4 had the least value. The amino acid profile showed that the Glutamic Acid, Aspartic Acid,Valine, Threonine, Serine, Phenylalanine, Proline and Methionine increased in value while Lysine, Leucine, Arginine, Alanine, Isoleucine , Glycine, Histidine and Tryptophan reduced in value and there was no significant change in cysteine (%) all  were significantly at (P<0.05). The haematological parameters of the catfish (Clarias gariepinus) juveniles fed graded levels of diets containing Tiny Moss (Bryum capillare) were not significantly different (P>0.05). The histological analysis of tiny Moss (Bryum capillare) feed shows normal skin architecture with well outlined epithelia cell (EC) moderate effect on the skin layer with moderate necrosis (N) of the muscular region with the epithelia lining and superficial spreading of melanoma (M) restricted to the epidermis. The heart shows normal cardiac tissue with cardiac cell (CC), cardiac fiber (CF) cardiac muscles (CM) shows moderate aggregate of myocardiac inflammation (AMI). The gill showed section of gill with ghost (G) appearance with severe aggregate of inflammatory cell (AIC). The liver cells revealed severe effect on the hepatic tissue with severe intra hepatic inflammation (IHI) and intra hepatic hemorrhage (IHIH). The damage done to these organs as the result of the feeds correlates with the concentrations of the feeds in each experimental tank.
