Fisheries is one of the sectors that can be developed to meet world food needs. The development of the fisheries is influenced by the availability of quality feeds. Dunaliella salina is a unicellular green algae that can be used as fish feeds. D. salina is known to contain many nutrients such as protein, carbohydrates, fats, pigments, and others. D. salina has also been shown to increase the growth rate of various types of fish. Not only for growth, but several studies have shown that D. salina has favorable effects on immunology. This article aims to explain the nutritional content and the effect of D. salina on the growth and health of fish. Based on the above studies, D. salina has the potential to be used as an alternative feed for various types of fish.

“…Β-carotene has benefits as an anticancer, antiaging, and immune system. In the research of Rusmawanto et al (2019), D. salina was macerated using n-hexane as a solvent; found to contain alkaloids, flavonoids, steroids, terpenoids and saponins, but terpenoids were not found in extracts with ethyl acetate solvent. Flavonoids, tannins, alkaloids, saponins, steroids, and quinnons contained in D. salina macerated with methanol solvent (Widowati et al, 2017).…”

Highlight Research Extract N-hexane of salina contains alkaloids, steroids, triterpenoids, and phenols Extract Ethyl Acetate of salina contains alkaloids, steroids, triterpenoids, phenols, flavonoid, and saponins Extract Methanol of salina contains alkaloids, steroids, triterpenoids, phenols, flavonoid, and saponins 24- hours LC50 value of the n-hexane extract salina was 276 ppm, the ethyl acetate extract was 673 ppm and the methanol extract was 811 ppm. All of the three extracts were included in toxic category Abstract Microalgae are single celled microorganisms as the primary producers in the water food cycle. Microalgae bioactive compounds was estimated to be 10 times more diverse than compounds produced by land plants. Microalgae use nutrients more efficiently to grow, metabolize, and produce chemical compounds. Dunaliella salina is a type of chlorophyte microalgae with a lot of potential to be used in various fields. This study aimed to determine the phytochemical compound content and the value of lethal toxicity (24-hour LC50) in microalgae D. salina extract with different solvents. The multistage maceration method uses n-hexane, ethyl acetate, and methanol to extract samples. Phytochemical screening uses reagents according to the content of secondary metabolites. The Brine Shrimp Lethality Test method is used to test toxicity. The extracts were tested by using 10 Artemia salina against five concentrations, namely 0, 1, 10, 100, and 1000 ppm. Toxicity data were processed through probit analysis to get the 24-hour LC50 value. The results showed that alkaloids, steroids, triterpenoids, and phenols were found in the methanol, ethyl acetate, and n-hexane extracts. Saponin were found in the methanolic extracts. Flavonoid were found in the methanol and ethyl acetate extracts. The 24-hour LC50 value of the n-hexane extract was 276 ppm, the methanol extract was 811 ppm, and ethyl acetate extract was 673 ppm. The three extracts were included in toxic category. Extracts of microalgae D. salina have plenty secondary metabolite, that can be used in various fields and holds the potential as an anticancer.

“…This condition is easy to control if it is in a closed cultivation system, but in an open cultivation system (Outdoor) it is rather difficult to control [3] . The main challenge in fish farming is the presence of pathogen attacks [4] and the availability of feed [5] , this can weaken the fish's body defense system, if not addressed immediately can result in fish death [6] , which is certainly very detrimental to the fishery, fishing industry players. The attack of bacteria and viruses as the cause of death in fish can cause a decrease in production and is very economically detrimental [7] .…”

“…The attack of bacteria and viruses as the cause of death in fish can cause a decrease in production and is very economically detrimental [7] . The bacteria that often infect fish are Aeromonas hydrophila, Pseudomonas fluorescens, Edwardsiella ictaluri [8] , Edwardsiella tarda [4] . The use of antibiotics in controlling disease in fish is highly recommended, but antibiotics have side effects, including causing bacteria to be resistant to these antibiotics, antibiotic residues can pollute the environment and accumulate in the fish's body, so that it will indirectly affect the human body that consumes them [1,9] .…”

The aquaculture sector industry is growing in order to meet the needs of animal protein at a price that is relatively affordable by various groups of people compared to other animal proteins. The development of the fisheries is influenced by the availability of quality fish free from disease attacks and good growth. Probiotics are good microbes that can suppress the growth of pathogenic microbes and can help accelerate fish growth. Various types of probiotics have been shown to increase the growth of various types of fish. In addition, various types of probiotics can also help prevent attacks of various types of pathogenic bacteria in fish. This article aims to explain various probiotics and the effect of probiotics on the growth and health of fish. Based on the above studies, various probiotics has the potential to be used as an alternative supplement for the Growth and Health of various types of fish.
