“…The increased opercula movements with continuous snout exposure could be due to respiratory distress while the adoption of different postures with sudden darts might be due to nervous compromise (ABALAKA and AUTA, 2010). Similar signs of toxicity were reported in C. gariepinus exposed to Caraca papaya and Nicotiana tobaccum (AYOTUNDE, OFFEM and BEKEH, 2011;KORI-SIAKPERE and OVIROH, 2011). This is in addition to hyperactivity and uncoordinated movements observed in ticks exposed to aqueous extract of A. obesum stem back (MGBOJIKWE, 2000).…”

“…There is therefore, a need to eradicate these hardy air-breathing fish from new habitats or earthen fishponds before re-stocking in order to safeguard native fish species or desired fish stock in earthen aquatic ponds. This is an important step in effective aquatic pond management as the former compete and/or prey on the later in addition to being able to surviving in moist burrows and mud even when such earthen ponds are drained (AYOTUNDE, OFFEM and BEKEH, 2011). Although air-breathing fish are normally resistant to toxicants (KULAKKATTOLICKAL and KRAMER, 1988), the use of synthetic chemicals to eradicate them from aquatic environments is well documented (TERAZAKI, THARNBUPPA and NAKAYAMA, 1980;GRIBGRATOK, 1981;MARKING, 1992).…”

Introduction: Histopathological effects of ethanol extract of Adenium obesum stem bark on the liver of Clariasgariepinus was investigated over a 96-h exposure period as an effective organic piscicide. Materials and Methods: An acute static toxicity bioassay was performed after a preliminary concentration range finding test was conducted. Results: Exposed fish showed adaptation behavioural changes with those of respiratory distress and abnormal nervous signs of toxicity, which was concentration-dependent. Mortality was recorded in some of the exposed fish while a median lethal concentration of 7.15 mgL-1 was established for the extract in the exposed fish. Non-significant (p>0.05) changes were recorded in serum aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase activities of the exposed ish. Moderate liver damage was observed in the exposed fish based on the degree of tissue change (DTC) grading where significant (p<0.05) differences were observed between the DTC of the exposed groups and the control. Conclusion: Ethanol extract of A. obesum stem bark was toxic to the exposed fish with evidence of hepatotoxicity and therefore, can be used to eradicate the hardy C.gariepinus from aquatic environments.

“…Use of pesticides and chemicals for the eradication of unwanted fish fauna and insects in fish culture ponds during pond preparation could have long-lasting impacts and may affect non-target organisms as well as human health through food chains and bioaccumulation. Non-target animals including the cultivated fishes are greatly affected by the indiscriminate use of the synthetic piscicidal agents [11]. Therefore, plant origin piscicides are preferred to synthetic ones because of the biodegradation potential and nonbioaccumulative nature of the former [7].…”

“…Clarias are important food fishes because of their large size, good flavour and rapid growth [1]. They are cosmopolitan and are widely cultured fish in the tropics and subtropics, and the third only to carp and tilapia, widely farmed fresh water fish in the world [2]. Presently, weed management has become a more serious problem because land fallowing, which was a method for controlling weeds in the tropics is no more tenable.…”

Success in fish culture is influenced by several factors. Elucidation of influences of some of these factors has become necessary as there is a lingering need to narrow the gap between supply and demand in the fish market in Nigeria. The influence of Atrazine (a systemic herbicide), coconut water (Cocos nucifera: also called coconut milk due to its rich nutrients content) and Phyllanthus muellerianus extract (a medicinal plant) on the gonads and liver were investigated. Ten fish were randomly selected and cultured in each tank containing 40 L of water for a particular treatment with three replicates. The average weight 76.26 ± 0.92 g and standard length 22.50 ± 0.61 cm were used for Atrazine experiment. For coconut water, the fish of weight 62.86 ±1.52 g and standard length 19.68 ± 0.73 cm were used. In Phyllanthus muellerianus experiment, fish with average weight 65.99 g and standard length 21.72.72 ± 0.92 cm were used. Atrazine and coconut water were lethal to Clarias gariepinus and had the LC5096 hours as 6.0 mg/L and 250.0 mg/L respectively. Phyllanthus muellerianus did not kill any fish for the fourteen day period of culture. All the three factors did not change the gonadosomatic index nor the hepatosomatic index significantly compared to the control. This observation did necessarily mean lack of influence on these organs but could be attributed to short periods for which the experiment was conducted.
