Fisheries play an important role in increasing the Nepalese economy as well as sustaining livelihood of some ethnic groups of our country. With the increased demand of fish, pisciculture have also increased to a great extend. Due to the rise in fish culture, there has been also rise in fish diseases. The study aims to investigate different parasitic, bacterial, fungal diseases in fish and to suggest treatment to control the diseases in four different fish farm of Nepal. A cross- sectional qualitative method was used to collect data from four selected fish farm (Kakani, Trishuli, Begnas, Mirmi) of Nepal. Infected fishes were transferred to the lab in oxygen filled plastic bags and further tested for bacterial, fungal and parasitic infection. The result of the study indicates that Epizootic Ulcerative Syndrome was the most common bacterial-fungal disease that had a significant impact on common carp fish especially in Trishuli, Begnas and Mirmi. Coccidiosis caused by Eimeria spp was found to be a growing problem in rainbow trout farming (Kakani, Nuwakot) infecting intestine, liver, gut and skin causing yellow diarrhea and skin lesions. Trichodina was observed number one problematic parasitic in carp culture not only in government farm like Begnas and Mirmi, but also in commercial farms in most of the fishery areas of the country. Fin rot were more commonly reported during winter months affecting common carp, Silver carp, Bighead carp, Fingerling Fish causing fin erosion in them. Ascites in brood fishes (Trishuli) was noticed which may be due to bacterial infection and due to nutritional deficiency. Besides this, white spot in the gills (a protozoan parasitic disease) was perceived and to control it Neodox with Formalin (150ppm) was used and was found to be very effective. This study also identified some fish health management related problems in fish farms of Nepal such as lack of assistance, poor technical knowledge, and lack of suitable diagnostic laboratory and their proper use.

An experiment was conducted for 190 days from September 15, 2005 to March 25, 2006 in 12 outdoor concrete tanks of 24 m2 (4.9 m × 4.9 m) size and 1.25 m in water depth, at the Institute of Agriculture and Animal Science (IAAS), Rampur, Chitwan, Nepal to evaluate the growth performance and profitability of silver barb in mono and polyculture systems. The experiment was laid out in a completely randomized design (CRD) with four treatments having three replications each. There was one mono and three polyculture systems of silver barb with different fish species as treatments: (1) Silver barb at 1.5 fish/m2 (control); (2) Silver barb at 1.5 fish/m2 plus common carp at 0.2 fish/m2; (3) Silver barb at 1.5 fish/m2 plus male Nile tilapia at 0.3 fish/m2; and (4) Silver barb at 1.5 fish/m2 plus carps at 0.5 fish/m2 (silver carp 40%, bighead carp 20%, and common carp 40%). Silver barb were fed with 23% CP feed @ 4% body weight daily.At harvest, the mean weight, daily weight gain, gross fish yield (GFY) and net fish yield (NFY) of silver barb in monoculture treatment were significantly greater than in polyculture with common carp (p < 0.05), whereas there were no differences with polyculture with Nile tilapia (p > 0.05). However, survival of silver barb was not significantly different among treatments (p > 0.05). The combined GFY in polyculture with Nile tilapia treatment was significantly greater than in polyculture with common carp and in polyculture with other carps (p < 0.05). The NFY was highest in polyculture with Nile tilapia (4.4 ton/ha/yr), intermediate in polyculture with other carps (3.5 ton/ha/yr) and lowest in polyculture with common carp (2.9 ton/ha/yr) and monoculture (2.5 ton/ha/yr). Water quality parameters were not much difference in different treatments; however, water temperature was a crucial as it was less than 20°C for about 3 months (mid November to mid February). All the treatments produced positive net returns; however, the net returns were higher in polyculture with Nile tilapia than in other treatments. This study demonstrated that silver barb polyculture with male Nile tilapia is far better than other combinations.Keywords: Silver barb, Monoculture, Polyculturedoi: 10.3126/on.v6i1.1653Our Nature (2008)6:38-46

The chemical and fatty acid composition were evaluated of commercially important fish species (common carp, silver carp, bighead carp, grass carp, Wels catfish, and zander) which were collected from retail stores in the area of Novi Sad, Republic of Serbia. The amount of protein was the highest in zander (19.27%) and the lowest in grass carp fillets (14.73%). The percentage of fat ranged from 1.8 in zander to 10.07 in common carp. The total cholesterol content was the highest in Chinese carps fillets (approximately 65.38 mg/100 g), and the lowest in Wels catfish (33.14 mg/100 g). SFA were lowest in zander (28.6%). Bighead carp meat contained the highest percentage of PUFA (33.73%) while the lowest percentage was detected in common carp (20.1%). The chemical and fatty acid compositions of fish vary greatly between different species and within the same species. The quality of fish meat in Serbian retail stores is quite good but it should be improved by using feed mixtures on fish ponds.

Causative Factors

In the Mississippi River Basin of North America, invasive bigheaded carp (silver carpHypophthalmichthys molitrixand bighead carpH. nobilis, also referred to as Asian carp) have spread rapidly over the past several decades. In the Illinois River, an important tributary of the Upper Mississippi River, reproduction appears to be sporadic and frequently unsuccessful, yet bigheaded carp densities in this river are among the highest recorded on the continent. Understanding the causative factors behind erratic recruitment in this commercially-harvested invasive species is important for both limiting their spread and managing their harvest. We analyzed weekly catch records from 15 years of a standardized monitoring program to document the emergence of age-0 bigheaded carp in relation to environmental conditions. The appearance of age-0 fish was generally linked to hydrographic attributes, which probably serve as a cue for spawning. However, we found profound differences in the number of age-0 fish among years, which varied by as much as five orders of magnitude in successive years. The strong link between summer flooding and age-0 fish production we observed emphasizes the importance of understanding the hydrologic context in which sustained invasions occur. Despite evidence of sporadic recruitment, bigheaded carp populations in the Illinois River appear to be consistent or increasing because of particularly strong, episodic year classes.
