ornamental Abstract: Barito Kuala District is the largest producer of the featherback (Notopterus chitala) in South Kalimantan Province, Indonesia. It contributes about 42.29% of total regional fisheries production.

No commercial aquaculture supports this business, so far. Data on capture fishery, fish processing business and fish farming were tabulated and analyzed using descriptive method. There was a great market opportunity for featherback chips in this area of study, where the demand of fish chips (36 tons/year) was six times higher than the supply to the market (6 tons/year).

摘要:Barito Kuala District是印度尼西亚南加里曼丹省(South Kalimantan)最大的羽背(Notopterus chitala)产地。它贡献了约42.29%的区域渔业总产量。最近，炸鱼片加工业务的原料供应和需求完全依赖于从河流捕捞。具有讽刺意味的是，羽背鱼的捕捞渔业产量趋于下降，这绝对影响了鱼产品的产量和销售费用。到目前为止，没有商业水产养殖支持这项业务。采用描述性方法对捕捞渔业、鱼类加工业务和鱼类养殖数据进行了制表和分析。在这个研究领域，有一个巨大的市场机会，对炸鱼片的需求(36吨/年)是市场供应量(6吨/年)的六倍。生产商的年平均利润为897美元。净现值(NPV)、内部收益率(IRR)和净效益成本比(Net B/C)分别为2796美元、137%和4.59美元，投资回收期(PP)为8个月15天，表明业务可行且有利可图，前景良好。为了增加价值，应该促进文化业务。曼迪安金淡水鱼养殖中心尝试对它们进行养殖;然而，结果仍然受到挑战，以克服这一问题。进一步探讨了这三个关键问题的理想联系。

The natural environment is polluted with various types of anthropogenic contaminants majorly from domestic, industrial and agricultural activities [1]. In recent years, the widespread use of agrochemicals to meet the agricultural demand of food production for the populace is expected. This has led to intensive and indiscriminate use of these agrochemicals, which results in the contamination of the aquatic ecosystems [2]. Consequent of continuous and arbitrary use of various types of pesticides in the field, water bodies are incessantly getting contaminated on a regular basis through run offs [3]. Aquatic pollution consequent of pesticides applications has become a critical issue especially in the developing nations of the world. Direct or indirect pollution of water by pesticides can lead to fish death, and reduction in fish population and productivity in the aquatic environment [4]. Apart from the instant warnings of mortality that may be obvious in the event of water pollution in cases of acute toxicity, however, organisms are subjected to long term effects consequent of chronic exposure which may also prove to be fatal to the organism or as toxicants to the final consumers of such organism [5, 6].

Like other countries, the Covid-19 pandemic is also widespread and rapidly reaching Indonesia, requires the government to immediately take policy steps to control its spread. The implementation of the Large-Scale Social Restriction rules resulted in limited space for movement and community activities in the public zone [1]. The Covid-19 outbreak not only created a health emergency but also have the impact on the global economic sector, including marine and fisheries sector. The impact is felt, among others, the price of fish dropped dramatically by 50% due to reduced market demand due to lack of buyers. Fish distribution has also experienced obstacles due to this policy. During the Covid-19 pandemic,many ecotourism locations were also temporally closed, and the sales of processed fishery products decreased significantly [2].

The Japanese flying squid, Todarodes pacificus, is generally infected by third-stage larvae of two species of anisakid nematodes. Anisakis sp. is typically observed encapsulated in the outer wall of the stomach and caecum of infected squids, whereas Lappetascaris sp. is found at the anterior end of the mantle musculature. To investigate the infection process, third-stage larvae of these two anisakid species were labelled by injecting a mixture of 5% fluorescein isothiocyanate-dextran and 5% biotin-dextran into their caudal end. The labelled larvae were placed inside the muscle tissue of dead prey fish which were then fed to freely swimming squids held within a large aquarium. Several days later, the squids were removed, killed and dissected to observe the characteristics of infection by fluorescing anisakids. Anisakis sp. larvae were found infecting the outer walls of the stomach and caecum, but no Lappetascaris infections were observed. Squids held inside custom-made plastic packs containing free anisakid larvae were not infected with Anisakis sp. but Lappetascaris sp. larvae were found attached to the gills. We conclude that Anisakis sp. penetrates the squid digestive tract after squids consume Anisakis-infested prey; while Lappetascaris sp. infects squids by direct entry through their gills following inhalation of ambient seawater.

Like other countries (e.g. Malaysia, Philippines, Thailand, Viet Nam, India and Bangladesh), the presence of Climbing perch (Anabas testudineus) in Indonesia also plays important role in both fisheries and aquaculture [1] due to its high quality meat, easy breeding, disease resisting, good consumer acceptance, and very adaptable to adverse environmental conditions such as low dissolve oxygenand thermal change [2,3].It is rich in iron and copper that support haemoglobin synthesis [4] and has high quality poly-unsaturated fats and many essential amino acids [5]. It also provides 19.50% of protein and 2.27% of lipid [6], whilecarbohydrate to lipid ratio (CHO: L) of 2.29 performed the best for growth performance, feed and proteinutilization and whole body composition [7]. This species inhabiting all freshwater bodies such as swamps, rivers, wetlands, canals, and reservoirs [8,9,10], and can be cultured at cages, tanks, nylon hapas, ponds and brackish water [11,12,13] with different culture management systems[14,15,16]. It is categorized by theInternational Union for Conservation of Nature and Natural Resources (ICUN) as avulnerable species.Habitat modification, destructive fishing practices, and polluted habitats may potentially threat this species [17,18,19].

: Hundred fifty rainbow trout of an average weight of 108 6.79g have been kept for sixty days in 700L tanks and various temperature regimes. They were fed two different diets, the one with probiotics containing Pediococcus acidilactici (CNCM MA 18/5M) and the other one without probiotics. All groups gained weight, however observed growth rate and weight gain have been considerably lower when fish over passed the 200g size class. No significant differences were shown between the two groups kept in lower temperatures in terms of growth rate, weight gain, feed conversion and protein utilization. Trout kept in natural temperature conditions fed either with probiotics or without probiotics, did not differ dramatically in between them in terms of growth rate and weight gain. However the ones fed with probiotics have experienced better feed conversion and protein utilization. Fish which have received dietary probiotics had lower serum cortisol levels and better Na+ and Cl- serum equilibrium than those which have not received probiotics, indicating that probiotics increased the stress resistance of experimental fish, even after the oxygen depletion test. Results of this study confirm that P. acidilactici in rainbow trout enhances its welfare and disease resistance and therefore should be used even at high size classes (100

The relationship between morphometric attributes and body weight of Babylonia areolata was analyzed using body weight(Y) and 11 morphometric attributes (X1-X11) from seven-month-old B. areolata. The results show that significant positive correlation between morphometric attributes and body weight, and all the correlation coefficients reach extremely significant level (P<0.01). The path analysis reveal that X2 display the highest positive direct effect (0.373) to body weight, and follow by X7 and X3. X10 affect body weight indirectly by X2, X3 and X7. The analysis results of determination coefficients show that the total decision coefficient of four morphological attributes to body weight is find to be 0.852, and indicating those morphological attributes are the main factor to body weight. The multiple regression equation is established by multiple regression analysis, the results show that all the best model for two-month-old B. areolata. are including: Y=0.003X22.513, Y=0.003X32.435, Y=0.001X72.597, Y=-6.496+1.329X10.

The success of catching Laher fish using stretch fishing rods is largely determined by bait. Siswoko et al 2013) explained that fishing would be more effective if the bait used could invite or stimulate fish. The same opinion was also reinforced by Rahaningmas& Mansur (2018) which states that the bait function is a lure to attract attention so that fish come close to the fishing line to prey on bait.
用加长鱼竿捕获拉尔鱼的成功与否在很大程度上取决于诱饵。Siswoko et al . 2013)解释说，如果使用的诱饵能吸引或刺激鱼类，捕鱼将更有效。rahaningmas&mansur(2018)也加强了同样的观点，该观点指出，诱饵功能是吸引注意力的诱饵，以便鱼类靠近钓鱼线捕食诱饵。
