Effects of organophosphate pesticide abate on the ovary of the cat fish, Heteropneustes fossilis (Bloch.)

The effects of the pesticide Abate on the ovary of the cat fish Heteropneustes fossilis (Bloch.) was studied by observing the vitellogenesis of the fish. The LC50 of Abate (0.64 ppm) after 24, 48, 72 and 96 hours of exposure to the fish was determined to be 14.3, 10.0, 6.61 and 5.13 ppm, respectively. The glycogen contents in the normal fish were lowest (6.0 mg/g) and highest (21.96 mg/g) in December and August, respectively; the protein contents were lowest (102.65 mg/g) in August and highest (424.17 mg/g) in December; whereas, the cholesterol was the lowest (9.32 mg/g) in November and highest (15.76 mg/g) in August. In the Abate treated fish, the lowest and highest contents of biochemicals were: 3.58 and 17.10 mg/g of glycogen in December and August, respectively; 80.44 and 378.34 mg/g of protein in December and August, respectively; and 7.15 and 12.92 mg/g of cholesterol in December and August respectively. The results show that the pesticide Abate has the potentiality to alter the vitellogenesis of the fish. DOI: http://dx.doi.org/10.3329/bjz.v40i2.14314 Bangladesh J. Zool. 40(2): 207-212, 2012

Bifenthrin is a type-I synthetic neopyrethroid pesticide having eight different stereoisomers. The current study aims to assess the short-term toxic effect of Bifenthrin to freshwater fish, Heteropneustes fossilis. The 24, 48, 72 and 96h LC50 values of bifenthrin to H. fossilis were 4.82, 4.47, 3.54 and 3.40 µg/l respectively. There was a significant variation (p<0.05) in the mortality of the treated fish exposed to bifenthrin with respect to the control at all the hours of exposure. A significant variation (p<0.05) between rate of mortality of H. fossilis and time slots (24-96h) was recorded for the final selected doses of bifenthrin except 4.0, 4.5 and 5.5 µg/l concentration of the toxicant. A vigorous mucous secretion and hyper-excitability was observed in the fish at the higher doses of bifenthrin specifically at 24h and 48h time slots. There was a profound loss in equilibrium of the treated fish particularly at the higher doses at 72h and 96h time slots. The gradual increase in dose of bifenthrin resulted in significant increase (p<0.05) in opercular movement of the fish with respect to the control. On the other hand, opercular movement showed a significant increase (p<0.05) with the advancement of time for all the treated doses. Therefore, bifenthrin is indicated to be very strongly toxic to fish.

Plasma Calcium Level

Adult fish Heteropneustes fossilis were divided into 4 groups –(i) Group A: kept in artificial freshwater and daily injected intraperitoneally with vehicle; (ii) Group B: kept in artificial freshwater and were daily injected intraperitoneally with 0.1 mg/100 g body wt of oProlactin; (iii) Group C: maintained in calcium-deficient freshwater and daily injected intraperitoneally with vehicle; (iv) Group D: kept in calcium-deficient freshwater and daily injected intraperitoneally with 0.1 mg/100 g body wt of oProlactin. Blood samples were taken 2 h after the last injection on 1, 3, 5, 10 and 15 days of the treatment. Plasma calcium levels were analyzed. The corpuscles of Stannius (CS) were fixed for histological studies. Artificial freshwater: The plasma calcium levels of vehicle-injected specimens (group A) remained unaltered throughout the experiment. Following prolactin treatment (group B) the plasma calcium levels progressively increased from day 3 to day 5. The values became normocalcemic at day 10 and day 15. After day 5 following prolactin administration (group B), the nuclear volume of AF-positive cells increased and the cells were seen degranulated. After day 10, there was an increased dilatation of sinusoids and the nuclear volume of AF-positive cells showed further increase. On day 15, these changes were exaggerated. The AFnegative cells of the corpuscles of Stannius of prolactin-treated fish (group B) showed no change in their histological structure and nuclear volume. Calcium-deficient freshwater: The plasma calcium level decreased in vehicle-injected fish (group C) from day 1 to day 3 (as compared to level of the fish kept in artificial freshwater). Thereafter, the level increased from day 5 resulting in hypercalcemia at day 10 and day 15. In prolactin treated fish (group D) the plasma calcium level indicated progressive increase from day 5 to day 15. In the vehicle-injected fish (group C) the AF-positive cells of corpuscles of Stannius showed accumulati

Hatching Rates

The present study compared the effectiveness of the Carp pituitary gland extract (PGE) and the synthetic hormone Ovaprim on spawning success of the stinging catfish, Heteropneustes fossilis during induced breeding. The PGE hormone was administered at 6 mg/kg of body weight for females and 2 mg/kg of body weight for males. In contrast, Ovaprim was administered at 0.3 ml/kg body weight and 0.1 ml/kg of body weight for females and males, respectively. The spawning success was higher in the Ovaprim-induced individuals with better performance recorded at all stages of spawning including latency period, ovulation, fertilization, hatching and incubation period compared to the PGE-induced individuals. In the Ovaprim induced individuals, the latency period occurred within 10 hours while in PG-induced individuals, the latency was after 15 hours. Similarly, ovulation rate was 90% for Ovaprim injected fish but lower 78.7% for PGE injected fish. Higher rate of fertilization was observed in the eggs of Ovaprim treated fishes 86.7% compared to 69.2% in PGE induced fish. On the other hand, hatching rate was 76.9% in eggs spawned from Ovaprim induced individuals compared to 72.7% in PGE induced fish and the incubation period was also shorter at 3.5 h for eggs from Ovaprim-induced fish while the PGE induced fish eggs required a 5-h incubation period. Finally, the results showed that Ovaprim treated fish yielded better results compared the PGE treated fish in terms of ovulation, fertilization and hatching rates of H. fossilis.DOI: http://dx.doi.org/10.3126/on.v10i1.7755
