EFFECT OF BROMACIL AND BIOFENOX ON CHANGES IN BIOCHEMICAL CONSTITUNTS IN FEW ORGANS OF A FRESH WATER TELEOST CHANNA GACHUA (HAM)

In the present work an attempt has been made to study the effect of weedicides – Bromacil and Biofenox on changes in biochemical composition in whole body in a fresh water air breathing teleostean fish, Channa gachua (Ham.). Exposure of sublethal concentrations of both the weedicides brought considerable decrease in lipid, carbohydrate and ash content in stomach, intestine, liver, ovary and testis. The protein content did not vary to a significant level after such treatment. However, the water content in various organs increased to a considerable level. The reason for such changes has been discussed in this paper.

CORRELATION BETWEEN CYCLIC CHANGES IN BLOOD PARAMETERS AND OXYGEN UPTAKE IN ANABAS TESTUDINEUS (BLOCH)

In the present work an attempt has been made to study the correlation, if any, between the cyclic changes in oxygen consumption (Vo?) and different haematological parameters in an air breathing fish, Anabas testudineus (Bloch). Two peaks of activity were marked in both the parameters. A positive correlation occurs between RBC/VOZ. Hb/Vo2 and PCV/Vo2 in both the sexes. The increase in VO2 seems to be more associated with the increase in RBC counts than with the increase in Hb content and PCV. Cyclic changes in Vo2 and different blood parameters show parallelism and a physiological balance exists between these two parameters.

Studies on the effect of sublethal concentration of Herboclin (weedicide; 0.30 mg/l) and phosalone (an organophosphate pesticide, 20. Omg/I) were made to evaluate the changes in total proteins (wet weight) content in few tissues (namely -Testes, ovary, liver and muscles) in an air breathing murrel fish, Channa gachua (Ham. ). The exposure of fishes to sublethal concentration of both Herboclin and phosalone caused significant decrease in total protein content as compared to control. The effect was more pronounced in phosalone treatment as compared to control. The reason for such changes has been discussed in this paper.

The effect of sub/ethal dose (0.3mg/l) of an organochlorine pesticide, Lindane on impairment of pituitary gland has been studied in a fresh water teleostean fish, Mystus vittatus (Bloch). The treatment of Lindane for 90 days in the fish caused significant decrease in the almost all the types of cells (two types of both each acidophils and cyanophils and one type of chromophobes) of pars proximal dista/is as compared to control. The reason for such changes have been discussed in this paper.

EFFECT OF GONADAL STEROIDS AND PHARMACOLOGICAL AGENTS ON GONADAL ACTIVITIES AT TWO TEMPERATURES IN ANABAS TESTUDINEUS (BLOCH)

http://pzsi.anveshika.org/proceedings-of-the-zoological-society-of-india/wp-content/uploads/sites/2/2017/06/Chapter-4.pdf

·

The present paper deals with the effect of hormones and pharmacological agents on the activity of gonads in Anabas testudineus at two different temperatures and different periods of breeding cycles. In males at high temperature 31°C, in May when the testes were matured and full of sperms, the treatment of ovocyclin, duogynon forte and testosterone propionate (T.P.) brings about significant decrease in 68! as compared to control indicating that these agents play an important role in the release of milt but at low temperature (22°C, in January) when the testes were in regressed condition except TP. all the agents failed to exhibit any significant change in the testicular activity. Fertyl in males and ovocyclin in females has no effect on the gonadal activity. At high temperature (31°C) the treatment of lutocyclin, fertyl and duogynon forte brings about significant decrease in G8! in females indicating that these agents are concerned with the maturation and finally ovulation of eggs but at low temperature except fertyl all the the agents failed to bring any significant change in GSI. The effect of different agents seems to be temperature dependent.

A COMPARATIVE STUDIES ON THE EFFECTS OF AGROCHEMICALS ON BIOENERGETIC MODELLING IN CHANNA PUNCTATUS (BLOCH)

http://pzsi.anveshika.org/proceedings-of-the-zoological-society-of-india/wp-content/uploads/sites/2/2017/06/Chapter-2.pdf

The effect of two agrochemicals namely urea and ammonium sulphate on changes in bioenergetic mode/ling has been studied in a fresh water air breathing snake headed murrel, Channa punctatus (Bloch). This study indicated that both the above noted agrochemicals caused appreciable decrease in food efficiency, daily individual growth increment (g/fish/day) and energy value for production of new tissue (P) but on the otherhand the maintenance energy expenditure (i.e. F+U+R) in experimental animals increased as compared to control. The reason for such changes has been discussed in this paper.

·

The effect of an organochlorine pesticide, lindane at different time intervals of 24, 48, 72 and 96 hrs was studied on the toxicity (LC Values), opecular beatings and behavioural response in a fresh water fish, 50 Mystus vittatus (Bloch). The response of the fish towards toxicity was grossly dependent on concentration and length of exposure. The mean values of opercular beatings decreased with increasing concentration of lindane. The reason for such changes have been discussed in this paper.

Studies on the effect of sublethal concentration of Herboclin (weedicide) and Phosalone (an organo phosphate pesticide) were made to evaluate the changes in some haemato-biochemical parameters in an air breathing teleostean fish, Channa gachua (Ham.) In control group of fishes the values of serum protein, blood glucose and serum cholesterol were respectively 4.89 + 0.43, 69.83 + 2.15 and 144.85 + 2.18 mg/100 ml. The exposure of fishes to sublethal concentration of both Herboclin and phosalone caused significant decrease serum concentration of serum protein while such exposures caused significant decrease in serum blood glucose and serum cholesterol. The reason for such changes has been discussed in this paper.

The effect of two agrochemicals namely-ammonium sulphate and urea on changes in total oxygen consumption has been studied in a fresh water teleostean fish, Channa punctatus (Bloch). Total oxygen consumption in this fish was 86.54 + 1.4 cc/kg/h. Treatment of sublethal concentration of both urea & ammonium sulphate for 96hrs exposure caused significant decrease in oxygen consumption as compared to control. The effect was more pronounced in ammonium sulphate as compared to urea exposure. The reason for such changes has been discussed in this paper.

STUDIES ON CHANGES IN HAEMATOLOGICAL INDICES IN RELATION TO BODY WEIGHT, LOCALITY AND SEX IN TWO SPECIES OF CHANNA

·

Studies on different blood parameters were made in relation to body weight, locality and sex in Channa punctatus (Bloch.) and C. gachua (Ham). The RBC count, Hb content, WBC count and PVC increases with the increase in body weight by a fractional power of 0.16, 0.16, 0.30 and 0.57 (regression coefficient) respectively in C. punctatus. The correlation coefficients were high, ranging from 0.93 to 1.0. No statistical relationship could be obtained between the body weight and different blood parameters in C. gachua. Significant difference was found in different blood parameters in C. punctatus collected from two different localities. The blood parameters in males and female in the two species did not differ significantly.
