In a pilot scale study, silver and copper nanoparticles were synthesized from two different plant sources viz Flacourtia indica and Prosopsis juliflora. The in vivo toxicity of silver and copper nanoparticles was tested on Danio rerio (Zebra fish) under different concentrations (1 ppm, 10 ppm and 100 ppm). Through the investigation, the nanoparticles treated fishes developed with hyper pigmentation in the ventral region. The minimum lethal concentration required to bring lethality caused by silver nanoparticle was 10 ppm whereas for copper nanoparticles it was 1 ppm. Further, the concentration of silver and copper nanoparticles accumulated inside the fish was evaluated by Atomic Absorption Spectroscopy. The in vivo concentration of silver and copper nanoparticles steadily increases with increase in dosage of nanoparticles being tested.

The effect of stocking density on growth of zebra fish was examined. Total five different stocking densities (5, 15, 25, 35 and 45 individuals per 2 liters of water) were maintained in triplicate for a period of 60 days. One month old zebrafish were randomly stocked into 15 tanks and fish were fed with commercial diet. The mean weight gain, specific growth rate and length gain for treatment 1 (5 fish/2liter) and treatment 2 (15 fish/2 liter) were significantly (p < 0.05) higher than treatment 3 (25 fish/2 liter), treatment 4 (35 fish/2 liter) and treatment 5 (45 fish/2 liter). The gender weight gain, survival rate and condition factor did not show any significant (p > 0.05) difference among treatments. The result of this study suggests that the stocking density of zebrafish could be 15 fish per 2 litre of water in a laboratory system with aeration.Bangladesh J. Zool. 44(2): 209-218, 2016

Complex Habitat

We tested the predictions that an increase in the structural complexity of a habitat causes both a decrease in aggression and the monopolization of resources. Groups of three zebra fish (Danio rerio) were allowed to compete for food in a complex habitat with simulated vegetation and in a simple habitat with no vegetation. As predicted, both the levels of aggression by the dominant fish (P = 0.050) and the coefficient of variation of the amount of food eaten within a group (P = 0.020), a measure of food monopolization, were lower in the complex habitat than in the simple one. Fish that chased competitors more frequently ate more food in both habitats, but the relationship was stronger in the simple than in the complex habitat. Our results suggest that aggression is less useful as a mode of competition in habitats with greater structural complexity. Manipulating the structural complexity of the habitat may be a practical way of controlling the intensity of aggression and resource monopolization in groups of animals.
