“…At present, some measures have been used in freshwater aquaculture to treat bacterial diseases, among which the use of probiotics has been overwhelming advantageous (Jamal, Abdulrahman, Al Harbi, & Chithambaran, 2019; Perez‐Sanchez, Mora‐Sanchez, & Luis Balcazar, 2018). Related research demonstrated that active natural products synthesized by probiotics regulated physiological function, improved gastrointestinal morphology and microbiota and the breeding environment, and inhibited the colonization and proliferation of other organisms (Dominguez‐Borbor et al., 2019; Huang, Zhou, et al, 2020; Ju et al., 2020; Nwachi, 2013). Probiotics have been widely applied in fish and shrimp farming, which provides new ideas and directions for the prevention and control of mussel diseases.…”

In August 2019, massive mortalities of cultured Hyriopsis cumingii occurred in a local shellfish breeding experimental base in Chongqing, China. In this report, we identified 14 isolates from cultured mussels in mortality events and demonstrated that these strains caused mortality from 9% to 97%. Significant mussel mortality (p < .05) was observed in association with most isolates after bacterial challenge; however, considerable variation in the virulence of different isolates was noted, with survival ranging from 3% to 88% after 7 days. The most virulent strains (HOP3 and GL1) in haemolymph and tissues were identified as Stenotrophomonas maltophilia and Aeromonas veronii based on biochemical and 16S rDNA sequence analysis. The LD50 values of HOP3 and GL1 were found to be 2.45 × 106 CFU/g (body weight) and 2.24 × 105 CFU/g (body weight) respectively. Histopathology of H. cumingii infected with S. maltophilia and A. veronii displayed degeneration of muscle fibres and gill necrosis. We tested the antibiotic susceptibility of the two isolates and found that HOP3 was multidrug‐resistant. Growth optimization study revealed that both isolates remained surviving across wide environmental ranges. Our data lay the foundation for the pathogenic mechanism of mussel bacterial diseases, and they also suggest that effective control measures are worth further investigation.

“…Recently, it used for feeding of fish fry in aquaculture ( Barthelmes, 1969;Huet, 1970;Masters, 1975;Paray and Al-Sadoon, 2016). It is characterized by size suitable for the mouth opening of many fish larvae and fish fries such as Oreochromis niloticus as well as it has a high nutritional composition (Nwachi, 2013;Gogoi et al, 2016;Herawati et al, 2017). Its nutrient content varies according to the culture medium and the degree of availability of phytoplankton (Damle and Chari 2011;Herawati et al, 2017).…”

“…The goal of the fermentation process is to increase the content and quality of protein, maintain the nutritional value during storage, and reduce the anti-nutrient substances of the feed ingredients. The fermentation process can also increase the nutritional value of ingredients in the meal (Nwachi 2013). Fermentation is the anaerobic dissimilation process of organic compounds mediated by the activity of microorganisms or extracts from the cells of these microorganisms (Abu et al 2013).…”

“…Fermentation is the anaerobic dissimilation process of organic compounds mediated by the activity of microorganisms or extracts from the cells of these microorganisms (Abu et al 2013). The purpose of fermentation is to shorten the long chain of amino acids and fatty acids to facilitate the absorption of feed during metabolic processes using probiotic bacteria to enhance growth and enrich nutrients in the larval feed (Nwachi 2013). The advantages of the fermentation process include the ability to improve nutrients, especially proteins and fats, produce specially scented food, and increase energy efficiency and ease of use.…”

Abstract. Herawati VE, Pinandoyo, Darmanto YS, Rismaningsih N, Widarto S, Radjasa OK. 2020. The effect of fermented duckweed (Lemna minor) in feed on growth and nutritional quality of tilapia (Oreochromis niloticus). Biodiversitas 21: 3350-3358. One of the raw materials used for making tilapia fish feed is soybean meal. Soybean prices continue to rise and currently reach 4,500 rupiah/kg, so that alternative feed ingredients that are cheap and environmentally friendly need to be sought. Alternative feed ingredients that can be utilized in making feed, one of which is Lemna minor meal. Duckweed (Lemna minor) which has a high nutrient content, such as 23.47% crude protein, 3.99% crude fat, 29.92% crude fiber, 23.6% ash, and 19.02% nitrogen-free extract, will be the best candidate as an alternative feed ingredient. This study aims to find growth performance and nutritional quality of tilapia fed by different feed formulations using different amounts of fermented L. minor meal. The dosage treatments of feed with fermented L. minor meal are 0% (A), 2.5% (B), 5% (C), and 7.5% (D). Feeding of tilapia using fermented L. minor meal has a significant effect (P<0.05) on total feed consumption, feed utilization efficiency, protein efficiency ratio, and relative growth rate, and had no significant effect (P>0.05) on survival rate. The results found that the best biomass weight, total feed consumption, feed utilization efficiency, relative growth rate, protein efficiency ratio, and survival rate value was in the treatment B (usage of 2.5 % L. minor meal) which were 38.58g, 110.17g, 70.10%, 2.01%, 1.98%, and 94.44%, respectively. The best nutritional quality was in the treatment B (usage of 2.5 % L. minor meal) which was amino acid lysine, the highest value of amino acid lysine was 25.22% and the highest value of linoleic fatty acid was 4.37%.
