“…is commonly used as a live feed for freshwater fish, especially in the early stages of their development (Adeyemo et al, 1994;Suminto & Nugroho 2019). Among the species used as live feed are M. dubia (Adeyemo et al, 1994), M. micrura (Edeh et al, 2021), and M. macropa (Suksomnit et al, 2011;Islam et al, 2017). Moina sp.…”

Due to their small size and high nutritional content, Moina sp. is an excellent food source for young fish such as Nile tilapia, African catfish, guppy, and carp. Moina sp. is increasingly being utilized as live feed in aquaculture, particularly in hatcheries. However, Moina sp. frequently obtained from contaminated environmental sources such as sewage with unsteady production. Thus, in order to use Moina sp. as a hygienic and sustainable source of livefeed, in this study, two culture system i.e. semi-open and open culture system, were developed and its production performance were analyzed. The highest production amount per cycle per tank for semi-open system was 733.3 ±251.7g and for the open system the highest production amount was 1463.7 ±348.2g. The mean for total biomass production in the semi-open system monthly was 6.26 ±0.92kg. Meanwhile, for the open culture system, almost five fold more production was recorded during the culture period which was 33.5 ±8.92kg. Based on the production performance of both culture system per metric tonne (MT) within the ten-month period of study, the total Moina sp. biomass produced per month per MT was almost comparable. In this study, the productions of both systems per tank per cycle in each system were consistent. The open culture system recorded significantly higher production of Moina sp. per culture cycle per tank compared to the semi-open system. The overall total productivity of each culture system every month, on the other hand, fluctuated slightly. Both culture system could be used to mass produced Moina sp. The study's findings were crucial for the prospective mass production and sustainable of Moina sp as live feed in aquaculture.

“…However, the predation of larval fish in nursing ponds by water insects presents a serious obstacle to seed production in rural areas 2,4 . Several previous studies have suggested countermeasures for the extermination of predatory water insects 1,2 , but these have not been used effectively to prevent predation. This is at least partly due to the lack of basic information regarding fish seed predation, including that in which predatory species are involved.…”

The predation of cultured larval fish by water insects presents a serious issue for aquaculture development in rural areas of the Lao People's Democratic Republic (Lao PDR). In this study, the species composition of predatory water insects was monitored in a fish nursing pond. Laboratory predation experiments were then performed to examine the predation potential of water insects on 3 major cultured fish species, including Barbonymus gonionotus, Cirrhinus cirrhosus, and Cyprinus carpio. Anisops spp. was considered to have the highest impact on mortality by predation in Lao PDR. It was estimated that Anisops bouvieri can prey on 10.4-46.7% of larval fish within 24 h under standard rearing conditions recommended by FAO.
