The Cost

Feeding is one of the main methods of intensification of agricultural fish farming. Based on FAO reports, the share of aquaculture products grown with feed is gradually increasing. In pond farms with medium and high degree of intensification, up to 80% of fish products are produced due to feeding. Moreover, in the structure of the cost of fish production, compound feeds account for up to half of the total costs, and in industrial aquaculture up to 65–70%. It is shown that it is Known that feeding and growing technology account for about 55% of the success rate of increasing fish productivity, while the genetic potential is only about 25%, and the share of veterinary and sanitary well-being of fish accounts for about 20%. In Russia and many other countries, cereals are used to reduce the cost of carp farming products, as a relatively cheap and affordable source of energy compared to granulated feed. The availability and low cost of such feed is of paramount importance in pond aquaculture and currently all cereal species are used for artificial feeding. Information about feeding carp with grain crops, as well as requirements for the quality and safety of feed is provided. It is indicated that feeding carp with whole grains is advisable if the natural food base is well developed. Traditional fish farming experience shows that feeding carp with whole wheat grain is advisable when the planting density of two-year-olds is up to 3.5 thousand / ha and mainly in August-September. Before eating fish, the grain must necessarily swell in water, otherwise it injures the intestines and is excreted from the digestive tract poorly digested.

Treatment Measures

The present study was conducted to know the culture strategies and fish health and disease problems in pond aquaculture in Mymensingh, Bogra and Pabna districts of Bangladesh. Questionnaire interview and participatory rural appraisal tools like focus group discussion (FGD) were conducted with selected fish farmers. In total 90 farmers were interviewed and 9 FGD sessions were conducted. Most of the respondents practiced carp and pangas polyculture and they had disease problems in their ponds. Prevalence of fish disease varied with cultured species and locations. The most prevalent diseases as reported by the farmers were pop eye (57.78%), ventral reddening (55.55%), tail and fin rot (48.89), hemorrhagic lesion over the body surface (45.56%), dropsy (40%), gill rot (40%), white spot (40%) and epizootic ulcerative syndrome or EUS (33.33%). According to farmers opinion most susceptible species to disease was silver carp, Hypophthalmichthys molitrix (57.78%); followed by mrigal, Cirrhinus cirrhosus (50%); catla, Catla catla (47.78%); sarputi, Barbodes gonionotus (47.78%); rui, Labio rohita (42.22%) and pangas, Pangasianodon hypophthalmus (42.22%). Higher mortality was found in pangas (53.56%). Clinically, pangas, koi and sarputi were found severely affected. Most of the farmers used some treatment measures against disease problems. This study also highlited some fish health management problems in pond aquaculture. Further studies should include identification and characterization of pathogens involved in different types of diseases in pond aquaculture. DOI: http://dx.doi.org/10.3329/jbau.v11i2.19944 J.

Aquaculture Production

The seasonality of fish marketing is a very important character for aquaculture production. We analysed data regarding the situation at the Czech market in 2015 and 2016 available in the information system of the State Agricultural Intervention Fund. The most significant volumes of freshwater fish were traded by traditional pond aquaculture companies (TPA) and approx. 1/3 of the all‑year production was sold at the end of the year (December). Another significant time when the supply of live fish from the TPA on the domestic market slightly increased was in March and then in April, i.e. before Easter, which represented approximately one fifth of all aquaculture production. The weakest periods in terms of marketing fish of TPA were the beginning of the year, i.e. during the first two months (January and February) and the period from May to September. On the contrary, the situation was different in intensive fish aquaculture companies (IA) which had the most significant volumes traded between April and September and then in November and December. However, the sold volume of fish from IA was not strictly concentrated in a single period.

Abstract This study was conducted in the Daitu district of Thainguyen, Vietnam during November 2001 to January 2003 to identify and estimate potential areas for aquaculture development in a watershed area by integrating socio-economic and environmental data into a geographical information system (GIS) database. Fourteen base layers were used for land evaluation and grouped into four main land use requirements for aquaculture namely: (1) potential for pond construction (slope, land use type, soil thickness and elevation); (2) soil quality (soil type, texture and pH); (3) water availability (distance to water, water sources and precipitation); and (4) geographical and socio-economic factors (population density, distances to roads, local markets and hatcheries). The study demonstrated the usefulness of GIS modelling to select suitable sites for the development of watershed ponds, and the importance of using the data as a tool for planners to develop strategic plans for aquaculture development. The study indicated that about 4.7% (2,725 ha) of the total land area of 57,618 ha in Daitu district was suitable for watershed pond aquaculture, compared to the existing 404 ha of watershed ponds.

Abstract A total of 600 oxbow lakes are located in the southwestern part of Bangladesh, covering 5,488 ha. An oxbow lake (baor) is an old cut-off river bend, usually in the shape of a horseshoe. Pond aquaculture for women was introduced in oxbow lakes in 1995-1996 to allow their active participation in aquaculture as a livelihood activity. The shallow and silted parts of the baor were excavated into 0.5 to 1.5 ha size fishponds. This study was conducted in 1999 in two selected oxbow lakes in Jessore district to assess the technological and socio-economic effects of fish farming groups (FFGs) and pond aquaculture in oxbow lakes with emphasis on the involvement of women. Three categories of questions (socio-economic, technical and gender) were asked of FFG members. This study shows that initially when the women became involved in pond excavation and dike compaction, as members of the FFGs, most of their men members did not like this. As Bangladesh is a Muslim-dominant country, there is a general idea among men that women should not work outside together with men. However, after a few years, once the success of the women's fish farming activities and marketing became clear, their social status and respect in the society and family increased through their active participation in this process. A total of 23 oxbow lakes in five districts around Jessore, covering 1,400 ha, have been handed over from the Ministry of Land to the Department of Fisheries (DOF). Subsequently, the DoF transferred the user-rights to the beneficiaries for a period of 50 years.
