“…It has been widely reported that deviations (in terms of toxicants) from the natural physiological formations has impacts on the histological functioning of fish exposed to plant extracts; Adenium obesum (Abalaka et al, 2015), Luffa cylindrica (Odioko et al, 2016) and Vernonia amygdalina (Audu et al, 2017) and many more. Akinrotimi et al (2012) affirmed that haematological studies are often used as a tool in determining the health status of fish species and also to detect physiological changes in stressed conditions such as exposure to pollutants and toxicants. The packed cell volume (PCV) of the fish across all treatments showed significant difference (p < 0.05).…”

This study examined the toxicity effect of Kigelia africana on Nile tilapia (Oreochromis niloticus) juveniles. The corresponding effects of this plant extract on the health status of the O. niloticus were similarly studied using their haematological and histopathological profiles. The experiment was carried out at the Hatchery Unit of the Federal University of Agriculture, Abeokuta fish farm. Fish were acclimatized for one week and fed twice daily at the rate of 3% body weight. Water in the culture medium was replenished daily. A total of 150 juveniles of O. niloticus were exposed to concentrations of 0.00, 1.75, 2.50, 3.75 and 5.00 g L −1 aqueous extract of Kigelia africana set up in three replicates. This toxicity study showed that aqueous bark extract of K. africana caused significant behavioural changes in O. niloticus. Recorded values of the water quality parameters showed significant difference (p < 0.05) across the treatments. The haematological indices of the fish were also observed to be affected with increasing extract concentration, compared to the control treatment (0.0 g L −1). Similarly, histology of the liver and gills showed variations in distortions and damages to the tissues; with observed severity increasing with increase in extract concentrations. This study suggested that the 96-h LC 50 of K. africana could be greater than 5 g L −1. The study concluded that caution must be taken in the disposal of this plant in water bodies as extended exposure time and at higher concentrations could pose adverse effects on the stock of juvenile Orechromis niloticus.

“…Numerous authors have reported the toxicity and haematological alterations in fish exposed to different chemicals in the laboratory [13][14][15]. Moreover, the use of hematological strategies in fisheries studies is developing rapidly, as it is very essential in toxicological research which bring about tracking and envisaging fitness situations of the fish [16,17].…”

“…The intensive nature of aquaculture has subjected farmed fish to a number of stressors which involves various handling procedures from hatchery to the final harvest stage [2]. When stress is induced by these handling procedures in the culture medium, fish react by consuming more energy to compensate for the elevated stress level, this subsequently activate secretion and release of hormones such as catecholamine and cortisol into the system of the fish, these hormones will impact negatively on the maintenance of homeostasis [3][4][5] and reduced fish performance in the culture medium [6]. Conversely, anesthetics are widely used in aquaculture to minimize the incidence of stress during culture operations and farming activities.…”

Background and Aim: The intensive nature of aquaculture has subjected fish to a number of stressors in the culture medium, anesthetics are widely used to minimize the issue of stress during farming operations and activities. Clove oil is a well known, established and acceptable anesthetics commonly used in aquaculture, this anesthetics is not readily available in developing countries, thus leaving the fish farmers with option of using the locally available plant extracts as anesthetic agent in fish culture. This study therefore assessed the efficacy of aqueous extracts of clove seed and its effect on hematological parameters of the fish.Methods: A total of 300 Clarias gariepinus comprises of 150 juveniles and 150 adult fish were exposed in triplicates to aqueous extracts of clove seed at concentrations of 5.0, 10.0, 15.0, 20.0 and 25.0mg/l at the rate of 10 fish per tank for both juveniles and adult fish. Induction time (Time taken for the fish to be completely anaesthetized) and recovery time (Time taken for the fish to resume normal swimming) was monitored using stop watch. Also, the effect of the extracts on water quality, survival and hematological parameters of the fish were evaluated using standard methods. Results:The result obtained revealed that the induction time indicated a size related response with the adult fish significantly (P<0.05) higher than the juveniles at all concentration of exposure. However, reverse was the case in recovery time, as the recover times in juveniles were higher than the adult fish. The survival was 100% in both sizes. Significant alterations were recorded in the haematological variables of the fish, which was more pronounced at higher concentrations of the extracts.
