Chronic Toxicity of Synthetic Based Fluid (Parateq©) on growth of three life stages of T. guineensis

Description

This study investigates the growth of three life stages of T. guineensis exposed to different sublethal concentrations of Parateq for 12 weeks in a static renewal bioassay. Parateq a synthetic based Fluid (SBF) was added to water to obtain the following sublethal concentrations 0.32%, 0.63%, 1.25 % and 2.5% vol/vol. Fry (0.64cm –0.65cm/0.52g – 0.55g) fingerlings (5.51cm–5.57cm/5.52g – 5.56g) and Post fingerlings (7.21 - 7.25cm / >10.5g) of T. guineensis were fed with NIOMR Feed. Proximate compositions of the feeds used were evaluated while the carcass composition of the fish was analyzed at the end of the experiment. Growth rates during the 12 weeks period were modest with fish in 2.5% of Parateq gaining the least weight. The highest percent growth rates were obtained from fish in control. The overall growth was significantly different between treatments and control. This study revealed that sublethal concentrations of toxicants will not only cause outright mortality but have significant effects which could lead to physiological dysfunctions in organisms that abound in the Niger Delta.
