Aquaculture industry in Malaysia involves culture of many fish species of either fresh or brackish water origin and among the important fish species are Snakehead, Tilapia and Catfish.  There is a substantial culture of these fish in Malaysia nowadays, though there are not one hundred percent native fish species but their presence in Malaysia is getting closer to over several decades and for almost a decade now, these species had been among the highest finfish produced in either fresh or brackish waters. As the global aquaculture production continue growing in order to meet up with ever increasing fish demand, especially as fish from capture has levelled off and makes an increase in aquaculture production as the only hope to meet the demand for fish, one of suggested ways in culturing them is by venturing into integrated fish farming. Integrated fish farming of different species is a practice which links together two or more normally separate farming systems, whereby the fish from different species become subsystems of a whole farming system. Although integrated fish farming may not be huge globally based on the available official statistical data but it is becoming important industry in Malaysia and neighboring countries. This review discussed briefly about the integrated fish farming of three commercially popular species (Snakehead, Tilapia and Catfish) in Malaysia and neighboring countries.

Abstract. Fatimah IN, Iskandar J, Partasasmita R. 2020. Ethnoecology of paddy-fish integrative farming (minapadi) in Lampegan Village, West Java, Indonesia. Biodiversitas 21: 4419-4432. In the past, the traditional paddy-fish integrative farming (minapadi) was predominantly undertaken by rice farmers in West Java, particularly in the water abundant areas. Currently, however, the practice of the rice-fish system has been dramatically reduced due to the Green Revolution programs, including water pollution that may have affected fish farming in paddy fields. Although the rice-fish systems have rarely been practiced in West Java villages, some farmer groups of Lampegan Village, Ibun Sub-district, Bandung District are still practicing the rice-fish farming system. The purpose of this study is to collect and document the traditional ecological knowledge (TEK) of Lampegan Village about the rice-fish system farming managements, including data on various fish species that are widely cultivated in the community, cultural practices of the rice-fish farming management, and benefits of the rice-fish farming system. A combination of qualitative and quantitative methods was used, with an ethnoecological approach. Techniques of data collection, such as observation, semi-structured interviews, or deep interviews, and structured interviews were employed in this study. The results of the study show that the farmers of the rice-fish farming in Lampegan Village, Bandung District own rich and deep knowledge of fish species and practice of the minapadi system. The TEK of the rice-fish farming management system has been inherited from ancestors and is mixed with western scientific knowledge. The rice-fish farming systems have provided some ecological and socio-economic benefits for village people.

Capture-based aquaculture (CBA) represents a type of intensive aquaculture production system for some economically valuable fish species, such as bluefin tuna (Thunnus thynnus), eel (Anguilla spp.) and Atlantic cod (Gadus morhua). In CBA, fish are captured from the wild in certain periods of the year, and following a recovery phase, they are kept in rearing facilities for a period of time, until they reach the market size. In this case, the fish are wild and have not gone through domestication like other fish species that are reproduced and farmed under the established farming systems. Therefore, these fish are not genetically adapted to live under the intensive farming conditions, and thus their welfare may be compromised in different manners compared to their domesticated counterparts. This review presents an overview of the current situation of CBA, while focusing on the assessment of fish welfare in CBA. The most commonly used fish welfare indicators will be discussed in relation to the different stages of CBA.

Abstract The integrated shrimp-mangrove system is one of the most important farming systems in the Mekong Delta, especially in the buffer zone of Ca Mau province, Vietnam. According to Decision No. 116/1999/QD-TTg of the Vietnam Central Government, farms could use up to 40% of the total area of the buffer zone along the coast for aquaculture, with 60% reserved for mangrove plantation and environmental protection. Currently the mangrove-shrimp farming system in Ca Mau occupies a total area of 47,500 ha, of which ponds (ditches) cover about 19,000 ha. Shrimp culture is based mainly on improved extensive methods that give productivities in the range of 200-400 kg ha-1 yr-1. In addition to shrimps, several other species such as mud crab, fish, and blood cockle are also stocked to diversify aquaculture production and ensure regular incomes. With newly issued policies and regulations for shrimp-mangrove farming systems, new opportunities are being created for further improvement and development of the system.

Freshwater Fish Species

The objective of this study was to survey the incidence of Flavobacterium columnare in wild and cultured freshwater fish species in Hungary. This bacterium usually causes disease in waters of more than 25 °C temperature. However, with the introduction of intensive fish farming systems, infected fish exposed to stress develop disease signs also at lower temperatures; in addition, the temperature of natural waters rises to the critical level due to global warming. Twenty-five isolates from wild and cultured freshwater fishes were identified as F. columnare by specific PCR, although both the fragment lengths and the results of PCRRFLP genotyping with BsuRI (HaeIII) and RsaI restriction enzymes raised doubts regarding this species classification. Sequencing of the 16S ribosomal RNA gene revealed that 23 isolates belonged to the species F. johnsoniae and two represented Chryseobacterium spp. The isolates were found to have high-level multidrug resistance: all were resistant to ampicillin and polymyxin B, the 23 F. johnsoniae strains to cotrimoxazole, 88% of them to gentamicin, and 72% to chloramphenicol. The majority of the 25 isolates were sensitive to erythromycin (88%), furazolidone (76%), and florfenicol (68%).

Aquaculture production in China has made large contributions to the global total volume of fish for human consumption. The developed mariculture fish species large yellow croaker (Pseudosciaena crocea) is the highest economic marine fish of China. As a schooling fish, large yellow croaker (LYC) usually migrates from northeast China to the southeast seacoast to over-winter. Indeed, there are several culture systems that can be applied for large yellow croaker, which should simulate the natural habitat for this fish species. The nutrition management of LYC has attracted researchers to study their nutrient requirements, growth, and other physiological characteristics. Here, we review the general biology (geographic distribution and habitat), hatchery development, aquaculture systems, and nutrition management of LYC. The paper aims to underpin the most significant investigations and highlight the future prospects for the LYC aquaculture industry in China.

Osmotic Balance

Aquaculture in Europe aims to diversify and optimize fish farming. The meagre (Argyrosomus regius) arose as a promising species due to its fast growth rates and flesh quality. Thus, it is currently being produced in several Mediterranean countries, mainly in sea-cages and salt-marshes. However, although meagre naturally spend the first years of life in brackish waters, to date it is cultured in seawater. Here, we show that juveniles may not successfully face either freshwater or hyper-osmotic environments as high as 55 ppt salinity. We found that 55 ppt induced catabolism and mobilization of energy metabolites stored in the liver, probably to maintain its osmotic balance. Furthermore, we found that osmoregulatory tissues such as gills managed to maintain plasma osmolality levels without differences in meagre acclimated at 5, 12 and 39 ppt salinity. Our results demonstrate the euryhaline capacity of this species, highlighting that juveniles may be cultured in a wider range of salinities rather than just at seawater. Future studies should focus on optimal environmental salinities for the growth of A. regius juveniles, including long-term experiments limited to the range of 5 ppt to full-strength seawater. Minimizing fish energy consumption in osmoregulation could be economically beneficial for the aquaculture industry in Europe.

Abstract Non-indigenous parasite fauna of freshwater fish has not been studied extensively in Croatia, despite the long history of introductions and translocations of alien fish species into inland waters. Negative implications for aquaculture production and wild native fish species have been frequently associated with the introduction of non-native parasite species. Hence, the present paper attempts to lay out a historical overview of the suspected localities, time frames and pathways of introduction for non-indigenous fish parasites into inland waters of Croatia, therefore producing a list of species. In total, 16 non-native fish parasites have been recorded in inland waters of Croatia, aquaculture establishments being identified as initial points of introduction. However, a paucity of information exists on the overall prevalence of infection as well as the economic impact on aquaculture production. In addition, limited information is available about the presence and potential ecological impact of non-indigenous parasites on endemic fish fauna in areas of high biodiversity, such as the water bodies of the Adriatic Sea Basin. Therefore, there is an urgent need and opportunity for multidisciplinary cooperation between different stakeholders, including government, scientists, in both biological and veterinary disciplines, and the industry, with the aim of extensive surveys to determine the potential impact on aquaculture production and wild fish population of high conservation value.

AbstractFreshwater fishes recorded in the territory of Slovakia include 95 fish species. As many as one third of these are allochthonous fish species belonging to 14 families, among which several have not occurred in Slovakia recently. Historically, there were three main periods of introduction: the first is the beginning of the 20th century, the second includes two decades between 1955 and 1975 and the third period is from the year 1990 up to the present time. The origins of the exotic species seen in Slovakia are the four continents — Africa (3), North America (7), Central America (3), and Asia (13) and ten of them are from different regions in Europe. The purpose of intentional introductions of non-native species was to occupy vacant ecological niches in the ecosystems reshaped by human activities, fish stocking, angling or fish farming. Some of these species spread from their original ranges or they penetrated spontaneously from the adjacent countries via the river network system. At the present time, 76 fish species in total form populations in Slovakia. There are 54 autochthonous and 22 allochthonous species, 14 of them are exotic fishes. The invasive characters in 13 fish species were considered, the recent native/total fish ratio is 0.71.
