“…The observed hyperexcitability (short TTE) of fish fed 1 g GN, 0.5 g GNNP and 1 g GNNP might be attributed to the action of GN and GNNP as anticholinesterase agent that can evoke hyperactivity with AChE impairment (Beauvais, Jones, Brewer, & Little, ). Inhibition of AChE activity might lead to accumulation of AChE in the carp brain, which may result in over stimulation of muscle contractions.…”

Novel study was performed to evaluate the efficacy of ginger (GN) and its nanoparticles (GNNP) on growth, cognition, immunity and prevention of motile Aeromonas septicaemia (MAS) in Cyprinus carpio fingerlings. Fish were divided into five groups fed diet 1 (control; no additives), diet 2 (0.5 g of GN), 3 (1 g of GN), 4 (0.5 g of GNNP) and 5 (1 g of GNNP) per kg feed for 30 days. In the behavioural test, fish were individually placed in a foraging maze to evaluate their cognition capability and feeding behaviour.At the end of feeding period, fish fed GN and GNNP showed significant better final weight than the controls. GN and GNNP significantly increased total protein, globulin and lysozyme, whereas 1 g GNNP group was the highest. One gram of GN, 0.5 g and 1 g GNNP enhanced cognition capability, while GN and GNNP increased percentage of fish fed in the maze. Brain acetylcholinesterase was significantly decreased than control in 1 g GN group. GNNP succeeded in the prevention of MAS more than GN, because no mortalities and 100% relative percentage survival (RPS) were detected in 1 and 0.5 g GNNP and 1 g GN per kg feed, while fish fed 0.5 g GN showed 20% mortalities and 71.4 RPS.

Male tilapia fish (Oreochromis niloticus) and water bugs (Lethocerus niloticum) were studied in a presence of malathion (diethyldimethoxy thiophosphoryl thiosuccinate) of commercial grade 57%. Fish were fed during the experimental period once daily on a commercial dry pellet ration, while water bugs were fed on fish offales. They all were acclimatized to the same laboratory conditions for 2 weeks before the beginning of the experiment. Different malathion concentrations were experimented. The present study revealed that the minimum malathion concentration level that induced mortality of water bugs without any lethality on Oreochromis niloticus fish was 0.26 mg/L for 96 hrs exposure period. However, some toxic effects and histopathological alterations were observed at that condition. Gonadosomatic index, serum Testosterone, T3 and T4 concentration levels were determined. Brain AChE and LDH activities were also analyzed. Fish liver, spleen, gills, testes, brain and thyroid gland samples were histopathological studied.

“…Although diazinon is not persistent in the environment, it is highly toxic to vertebrates including fish. Diazinon is a neurotoxin through its ability to inhibit acetylcholinesterase, 8 causing abnormal swimming behavior 9 and altered respiration and social interactions in aquatic organisms 6,8 . Water contamination with insecticides occurs mostly at concentrations that do not cause mass mortality, and sublethal effects are both more widespread and more important for population dynamics.…”
