Mass culture of fairy shrimp Streptocephalus proboscideus (Crustacea ? Anostraca) and its use in larviculture of the Persian sturgeon, Acipenser persicus

Abstract

This study was conducted with cysts of Streptocephalus proboscideus obtained from the University of Gent-Belgium. The cysts were hatched in Environmental Protection Agency (EPA) medium. The nauplii were reared at the Sturgeon Research Institute using a pure culture of Scenedesmus obliquus alga supplied at a density of 5 Â 10 3 cell mL À 1 that gradually increased to 1 Â 10 4 , 5 Â 10 4 and 1 Â 10 5 cell mL À1 with the growth of the nauplii. The nauplii attained sexual maturity and started producing cysts in 8 days and yielded a mean cyst number of 220 AE 40 female À1 brood À1 cysts. These cysts were used in the larviculture of Persian sturgeon, Acipenser persicus (Borodin). Forty-three larvae of Persian sturgeon (mean weight: 15.4 AE 1.1mg; mean length: 27.1 AE 2.7 mm) with roughly absorbed yolk sacs were stocked in three aquaria and fed S. proboscideus nauplii at 8-h intervals. By the end of the experiment (day 5), the mean weight and length of Persian sturgeon larvae were 51.4 AE 13.3 mg and 20.7 AE 1.4 mm respectively.

The in‐vitro antibacterial effects of organic salts, chemical disinfectants and antibiotics against pathogens of black disease in fairy shrimp of Thailand

“…Because of the importance of fairy shrimp as a live feed for aquaculture, there have been several studies on nutritional evaluation and cultivation patterns (Velu, Czeczuga & Munuswamy 2003;Namin, Arshad & Ramezanpoor 2007;Dararat, Starkweather & Sanoamuang 2011). Black disease is one of the major problems, which can lead to the collapse of the culture (Saejung et al 2011).…”

Improvement of nutritional quality of live feed for aquaculture: An overview

“…Nutritional compounds of fairy shrimps are most comparable with Artemia , which may contain high levels of nutritional quality and has essential amino acids, fatty acids and having high amounts of carotenoid complex antioxidants such as astaxanthin, canthaxanthin and antheraxanthin (Dararat, Sanoamuang, & Lomthaisong, ; Munuswamy, ; Velu & Munuswamy, , ). Fairy shrimp being utilized as diets for larvae, fingerlings and adult fishes, it has significant economic value in the aquaculture industry (Namin, Arshad, & Ramezanpoor, ; Sriputhorn & Sanoamuang, ; Velu & Munuswamy, , .) adult fishes.…”

“…Fairy shrimps can be freeze‐dried for later use or made into flakes or different kinds of formulated feeds like Artemia (Velu & Munuswamy, ). Regarding specific genera, Streptocephalus species many studies have been conducted to evaluate as food for larvae of different fish, prawns and ornamental fish (Ali & Dumont, ; Namin et al, ; Sriputhorn & Sanoamuang, ; Velu & Munuswamy, ).…”

Optimal egg viability storage conditions in two commercial fairy shrimps (Crustacea: Branchiopoda: Anostraca) from Thailand

“…Currently, fairy shrimp have received much attention as food for culturing fishes and shrimps (Dumont & Munuswamy ; Namin, Arshad & Ramezanpoor ; Sriputhorn & Sanoamuang , ; Velu & Munuswamy ; Plodsomboon, Maeda‐Martinez, Obregon‐Barboza & Sanoamuang ; Sornsupharp, Dahms & Sanoamuang ; Saejung, Hatai & Sanoamuang ,b; Sornsupharp, Lomthaisong, Dahms & Sanoamuang ). In Thailand, three fairy shrimps species ( Streptocephalus sirindhornae Sanoamuang et al .…”
