In the present work an attempts has been made to study the effect of few exogenous hormones on aquatic, aerial and total oxygen consumption (cc/kg/h) and equivalent energy utilization (E.E.U, K.Cal/hr) in an air breathing murrel teleostean fish, Channa punctatus (Bloch) with a view to assess whether or not these hormones have calorigenic action in this fish. Treatment with hydrocortisone, testosterone propionate and L-thyroxine brought significant increase in total oxygen uptake as compared to control fishes. The aerial oxygen uptake did not dffer to significant level in hydrocortisone treated group but in testosterone and L-thyroxine treated group it increased to a significant level. On the other hand, treatment with adrenaline, progesterone and thiouracil brought significant decrease both in aerial and total oxygen uptake as compared to control. The resons for such changes in bimodal oxygen uptake after the treatment with different hormones have been discussed in this paper.

‘In the present work an attempt has been made to study the effect of an organochlorine (MeritAlpha or Prophenofos) and an organophosphate (Mardo orAlpha Cypermethrin) pesticides on changes in acid and alkaline phosphatases in brain, liver and mucles in a freshwater major carp, Catla catla (Ham.). In the present study the inhibition in the activities of all the enzymes, assayed were found to be increased with the increase in the exposure of pesticides. Mardo and Merit Alpha were equally sensitive to both acid and alkaline phosphatase. The details have been discussed in this paper.

In the present work an attempt has been made to study total Cu-Zn SOD (Super oxide dismutases) activity (Units.mg-1 protein) in the liver of Labeo rohita (Ham.) collected from six different experimental sites (namely River Sone, River Koshi, Near Saharsa, River Ganga at Buxar, Patna, Mokama and Barh). Total SOD (antioxidant defence system) in liver were lowest at Buxar and Patna site of river Ganga and highest at Barh. Cu-Zn SOD were lowest at Buxar and highest at Barh. Mn-SOD activities were lowest at Patna and highest at Barh. The reason for such variations in SOD activities in liver tissues in a fresh water major carp, Labeo rohita (Ham.) has been discussed in detail in this paper.

Arsenic poisoning in ground water of Gangetic zone of Bihar causes lots of health issues to human. LD50 is a primary screening step for the evaluation of the toxic properties of a compound. The objective of present work to calculate the oral LD50 and MPD of sodium arsenite in mice. The present research, different doses like 10, 15, 18, 20, 25 and 30mg/kg body weight of Sodium arsenite was given orally by gavage method to the six different groups of Mus musculus. Signs and symptoms of toxicity and probable death of mice were observed on 1st day and then on 2nd, 3’d, 4th and 5th days to calculate the Median lethal dose (LD5O) and maximum permissible dose (MPD) of Sodium arsenite. The LD50 was found to 18 mg/kg body weight after oral administration in Swiss albino mice. Finally, MPD of Sodium arsenite by oral route in mice was found to be 2 mg/kg body weight.

STUDIES ON PHYSICO-CHEMICAL PARAMETERS OF WATER SAMPLES COLLECTED FROM DIFFERENT RIVER SYSTEM OF BIHAR

·

The present investigation was carried out to evaluate the magnitude of physico-chemical parameters in river system (namely river sone, river koshi near Saharsa, river Ganga at Buxar, Patna, Mokama and Barh) with a view to assess its suitability for fish growth and other purposes. The parameters studied were pH, temperature, D02, salinity and soluble or suspended inorganic constituents. DO2 of these sites have significant differences. Barh site of river Ganga was most suitable for fish growth and development while Buxar was most unfavourable site as evidenced by faunistic studies. The details have been discussed in this paper.

PESTICIDES INDUCED CHANGES ON BIOCHEMICAL PROFILES IN LIVER AND MUSCLES IN FRESH WATER FISH, CATLA CATLA (HAM.)

http://anveshika.org/proceedings-of-the-zoological-society-of-india/wp-content/uploads/sites/2/2020/12/9-dec-2020.pdf

·

 The present work is an endeavour to study the toxic effects on certain biochemical constituents (such as total carbohydrate, total protein and total lipids) of Mardo (orAlpha cypermethrin, an organophosphate) and Merit Alpha (or prophenofos, an organochlorine) in hepatic and muscular tissues of Catla catla after chronically exposing (15 and 30 days) the fishes to the toxicant. These pesticides caused significant decrease in total carbohydrate, total protein and total lipid both in the muscle and liver tissues in the fresh water Indian major teleostean carp, Catla catla (Ham.). The reasons for such changes have been discussed in detail.

EXPERIMENTAL STUDIES ON THE EFFECT OF L-THYROXINE AND THIOURACIL ON THERMAL TOLERANCE IN A CLIMMBING PERCH, ANABAS TESTUDINEUS (BLOCH)

http://anveshika.org/proceedings-of-the-zoological-society-of-india/wp-content/uploads/sites/2/2020/12/10-dec-2020.pdf

·

The present work is an endevour to study the effect of thermal tolerance in a fresh water air breathing climbing perch, Anabas testudineus (Bloch). The LC„ value of thermal tolerance of this fish (weighting 35.0±1.0g) was recorded to be 39.5±0.13°C. The L-thyroxine and thiourea treated fish showed statistically significant increase and decrease respectively in their thermal tolerance. The details of the mechanism has been discussed in this paper.

STUDIES ON THE BIOLOGY OF EARIAS VITELLA FABRICIUS (LEPIDOPTERA, CYMBIDAE ) ON THE PLANT ABELMOSCHUS ESCULENTUS OF RAMGARH, (JHARKHAND, INDIA ).

http://anveshika.org/proceedings-of-the-zoological-society-of-india/wp-content/uploads/sites/2/2020/12/3-dec-2020.pdf

·

The life cycle of Earias vitella Fabricius was completed on a cotton plant Gossypium hirsutum. It is a serious pest of cotton, and damages 75% of cotton which results poor production of the cotton crop. The present paper deals with the life cycle of Earis vitella Fabricius on a new vegetable plant Abelmoschus esculentus in Ramgarh (Jharkhand, India).

The life cycle Earias vitellaFabricius was studied during the year 2019 -2020 at Ramgarh .During the study it was found that the pest completed 6 to7 overlapping generations in a year. The pest enters the fruits of vegetable and protect themselves from the birds and cause a damage to the vegetables. The lady’s finger is a healthy and tastier vegetable, rich in carbohydrate, minerals and fibres . The pest damage the cultivated vegetable plants and cause loss not only the quality and quantity of the vegetables but also the profit of the farmers.

Ramgarh is a district town, the rural area is known for gross vegetable production, and marketing of the vegetables. The climatic condition of Ramgarh is moderate and suitable for vegetable production.

Foraging behaviour of the ants Anoplolepis gracilipes, Camponotous compressus, Crematogaster subnuda, Meranoplus bicolor, Monomorium pharaonis, Pheidole roberti and Tetraponera rufonigra was studied following supply of different food items in the open foraging ground with a view fo  note the interactions, if any. /t is revealed that, in spite of available foods at the supplying sites Paratrechina longicornis, Pheidole roberti, Anoplolepis gracilipes and Tetraponera rufonigra are habituated to face the food-snatching operations initiated either by the foragers of the same species belonging to different colonies or by the other competing species who are very much involved in sharing the food resources from the same foraging area. Food-snatching event is associated with the abrupt and brutal attack by the snatcher ant on the ants carrying food to their nest. Thus, fighting in most cases was inevitable and many of the food—transporting ant individuals were seen injured severely. The food snatching behaviour exhibited by these ant species was not only to ensure the need of their food but also a strategy to treat the competing ant species psychologically by imposing fearful threat, as a dominant species, not to visit the said foraging ground again, in future.
