AbstractFish, first jawed vertebrate group appearing in evolution, have immune system similar to those of mammals. These early animals' innate and adaptive immune systems are completely developed, having head kidney and thymus as primary, spleen and mucosa associated lymphoid tissue as secondary immune organs. The adaptive immunity performs key role in defence against recurring infections and elimination of fish pathogens with the help of its memory cells, T‐cell‐receptors and immunoglobulins. Epidermal secretions including antibacterial peptides, lysozymes, lectins, complement and C‐reactive proteins which function in disruption of antigens, phagocytosis, inflammatory response and mending of tissue injury play a significant role as elements of fish immune system. Fish, however, have greater innate immunity than humans do. Estrogens play crucial role in immunomodulation through nuclear oestrogen receptors, which are found in majority of immune cells and lymphoid organs in fish. There is mounting proof that xenoestrogens, that can attach as agonists to oestrogen receptors, pose significant ecotoxicological risk by disrupting the defence mechanism in fish. Though less potent than natural oestrogen, they can bioaccumulate to finally reach a substantial dose. This review's objective is to give an overview of the fish defence system, its estrogenic regulation and estrogenic‐endocrine disruption.

Growth of the ornamental fish industry is being hindered by the scarcity of low cost feed; hence alternative protein supplements should be explored. In this context the present study aims to evaluate whether the grasshopper Oxya fuscovittata could be used as a supplement for fish meal in the diets of Poecillia sphenops, which is one of the most common ornamental fishes worldwide. The present work is divided into three phases: In the first phase proximate composition of the grasshopper is obtained and five diets are prepared where fish meal is gradually replaced by Oxya meal and named as control, D1, D2, D3 and D4. All the diets are formulated on iso-nitrogenous basis where the protein percentage is fixed at 400 g/kg. The second phase deals with feeding trial and in the third phase all the data of the feeding trial are subjected to a linear model. The feeding trial shows that the control, D1 and D2 fed fishes have almost similar results. The linear model proves that the variation in the indices are mainly due to replacement of fish meal by Oxya meal, not due to the variations of rice husk and mustard oil cake that are also used to formulate the diets of the present study. From the results two Oxya supplemented diets, i.e. D1 and D2 are proved to be almost equivalent to the control diet. Hence it is concluded that Oxya meal is able to replace 25% to 50% of fish meal from the diets of P. sphenops.

Acridids could be an alternative source of protein for feeding to livestock as large numbers can be produced by rearing them on suitable food plants under optimum environmental conditions. The aim of the present study was to find a suitable food plant for the mass culture of the short-horn grasshopper Oxya hyla hyla (Serville). Food consumption and utilization, growth (growth rate, average daily growth, specific growth rate and wet weight gain), survival and life span of this insect reared on Sorghum halepense, Cyanodon dactylon and a mixture of these two plants were determined. The result revealed that the food utilization, growth and survival of this grasshopper depended on the food plant. The nymphs that were reared on C. dactylon consumed less food but had a greater efficiency of conversion of ingested food to body mass, growth performance and survival than those feed on the other two types of food. In contrast, the food consumption and utilization, growth and weight gain of adult grasshoppers was greatest when they were reared on S. halepense. These results indicate that of the plants used in this study C. dactylon is the best for rearing the nymphs and S. halepense for rearing the adults of Oxya hyla hyla.

Background. Enormous diversities exist regarding shape, number, and arrangement of the olfactory lamellae, distribution of the sensory and non-sensory epithelium as well as the abundance of various receptor cells among different teleosts. This study was aimed at describing the morphology, histology and SEM ultrastructure of the olfactory epithelium of a spotted snakehead fish, Channa punctatus (Bloch, 1793). Materials and methods. OE of C. punctatus was examined through LM and SEM. Results. Olfactory epithelium of C. punctatus containing 18 to 20 lamellae provides a large surface area. Sensory epithelium possesses both ciliated and microvillous olfactory receptor cells (ORC), which are intermingled and distributed throughout the epithelium. ORCs are arranged in alternate rows with supporting cells (SCs). ORC is columnar cell with a round cell body, an axonal process and a long dendrite. The apical surfaces of the ORCs are provided either with 10–12 cilia or numerous microvilli and the SCs with fingerprint like microridges. ORCs with rod-shaped dendrite ending were found in small numbers. Non-sensory epithelium is composed of ciliated nonsensory cells (cNSC) and covered with a dense carpet of cilia, which help in ventilating the olfactory chambers. Conclusions. A large surface area of OE, the high density of both ciliated and microvillous ORC and adequate arrangement for ventilating the olfactory chambers indicate that C. punctatus is very much dependent on its olfactory sense.

The stratified epithelial cells of the buccophaf} n." and oe sophagus are provided with simple and unbranched microridges in Notopterus notopterus. On the contraf)·, highly complex mi croridges on the epithelial cells of buccopharynx and oesopha gus are characteristic feature of Oreochromis mossambicus. In both the fishes the gastric mucosa is pr°'ided v1ith various mi nor folds forming empty concavities. The concmities are com paratively deeper in N notopterus. In the intestine of N no topterus the mucosa! folds are comparatively thinner and sim pler than 0. mossambicus.
