Haematological Profile of Oreochromis Niloticus (Burchell, 1822) Exposed to Cadmium Chloride
No full textChanges in Oreochromis niloticus blood cells were investigated after 96-h of exposure to cadmium chloride. One hundred and eighty (180) Oreochromis niloticus with average weight of 26.07±1.23g and mean length of 17.50 + 0.50cm were divided into 5 groups (T1-T5) at ten (10) fish per group and in triplicates after being acclimatized for 14 days. They were then exposed to various concentrations (0, 28, 30, 32, 34 and 36 mg/l) of cadmium chloride. The packed cell volume (PCV) of the treatments decreased significantly relative to that of the control, while their platelet counts increased compared with the control. There was also a reduction in the RBC (2.70, 2.51, 2.24, 1.98, 1.64 and 1.22) of treatments. Other blood parameters did not vary significantly in comparison with the control group, but it is worth noting that, the mean corpuscular volume (MCV) (70.78, 76.09, 83.71, 90.55, 105.49 and 128.68fL), mean corpuscular haemoglobin (MCH) (24.66, 24.49, 27.37, 29.83, 33.14 and 42.18pg) and mean corpuscular haemoglobinconcentration (MCHC) (34.83, 32.19, 32.71, 32.95, 34.41 and 34.78%) increased considerably in all treatments compared to the control. These alterations have been attributed to direct or feedback responses of structural damage to RBC membranes resulting in haemolysis and impairment inhaemoglobin synthesis, stress related release of RBCs from the spleen and hypoxia, which was induced by exposure to cadmium chloride. This study therefore gives an insight into toxic effect of cadmium chloride on fish

Aspects of Population Dynamics of Tiger Tooth Croaker, Otolithes ruber (Bloch and Schneider, 1801) from Northwest Arabian Gulf, Iraq
No full textThe present study consists of the growth, mortality, relative yield recruit and virtual population analysis of tigertooth croaker, Otolithes ruber from Iraqi marine waters, northwest Arabian Gulf between February 2020 and January 2021. Analysis of population dynamics employed methods fitted in FiSAT II software using pooled length-frequencies. A total of 3835 individuals of O. ruber ranged from 17.0 to 60.0 cm have been collected. The exponent (b) of the length-weight relationship was found to be 2.755. The von Bertalanffy growth parameters (L∞ and K) were estimated as 68.5 cm and 0.36, respectively, while the growth performance index (Ø\u27) was 3.228. The total mortality (Z) was calculated as 1.10, while the natural and fishing mortality rates were 0.69 and 0.41, respectively, and the current exploitation rate (Ecurrent) was 0.38. Fish were recruited to the fishery at a mean size of L50= 20.55 cm. The recruitment pattern of O. ruber was continuous throughout the year with two major peaks. The analysis of yield-per-recruit (Y/R’) indicates that the current exploitation rate was below the biological target reference points (E0.1 = 0.40 and Emax= 0.53), refer to the stock of O. ruber is underexploited. The 27 cm length group was more vulnerable to fishing and more harvested according to virtual population analysis. sLength at first capture was higher than the length at first maturity of the species in the region. For management purposes, more yields could be obtained by increasing the mesh sizes of the nets employed in the fishing of the species.
