After the yolk sac of fish larvae is absorbed, they will utilize external food sources such as natural phytoplankton and zooplankton. Specifically, one of the zooplankton species used is the small-sized rotifer Brachionus sp., which matches the mouth opening of the larvae. The purpose of the experiment was to examine the effects of providing live rotifer in combination with artificial feed on the survival rate and growth of Nile tilapia (Oreochromis niloticus) larvae in high salinity conditions. The Nile tilapia larvae used in the experiment were the offspring of Red Nifi strain breeders raised in freshwater and still containing yolk sacs. Feeding commenced after the yolk sacs were absorbed, and the salinity was gradually increased to 25-30 ppt. The larvae were fed with rotifers for seven days (P-1), 14 days (P-2), and then continued with another type of artificial feed. There was also a control group that only received artificial feed without rotifers. The stocking density of the fish larvae was 25 individuals per liter, and the total water volume used was 15 liters. The rotifer dose was maintained at 10-20 individuals per milliliter of water per day during the 4-week rearing period. The results showed that providing rotifers in water salinity between 10-15 ppt during the first seven days resulted in a survival rate of > 80%, whereas the control group achieved > 90% survival. However, the survival rate of the larvae started to decline from the second seven-day period with the increase in salinity between 15-25 ppt, and it continued to decrease to < 60% until the fourth week for all treatments.

“…In larval development, rotifer nutrition has received much attention, and many commercial solutions have been created to boost lipid and vitamin content [31,96]. Although theoretically possible to raise this zooplankton with a good nutrition, their performance are typically unsatisfactory due to poor hygiene standards and general condition (low swimming velocity, low reproduction rate, etc.).…”

Zooplankton are primary consumers and serves as a crucial connection between primary producers and consumers in the aquatic food chain and higher consumers. Plankton is consumed by more than 75% of fish species at some point throughout their life. Supply of live feed cultures is critical to the expansion of aquaculture enterprises, particularly the larviculture sector, which generates fish and crustacean seeds for grow-out businesses. However, zooplankton is rarely farmed in high enough densities to be commercially viable on a large scale. This is owing to dynamic changes in physicochemical conditions in the culture system, which would normally result in a shift in the reproduction pathway from parthenogenetic to sexual, which creates resting eggs and reduces overall live feed output. The density of these live feed organisms can alter in response to environmental conditions such as eutrophication due to an excess of nutrients, acidification, pollution, salinity intrusion, and other factors that occur within the system. The water quality and food supply in the system have a big impact on zooplankton population dynamics, especially in a culture environment. The goal of this review is to have a better understanding of the many strategies for growing zooplankton utilizing various fertilization methods in order to maintain a constant population density. This review focusing on the density of zooplankton, the biological responses of live feed to fertilization, and common challenges that farmers face in the culture. In particular, we (i) examine the many zooplankton culture techniques that have been developed over time, (ii) explain the biological reactions of zooplankton to changes in culture conditions, and (iii) show the frequent issues as-sociated with live feed culture.

“…Baker's yeast is commonly used in rotifer cultivation (Hoff & Snell, 2004; Rodriguez et al, 1994; Wang et al, 2003), especially activated baker's yeast which cannot cause excessive bacterial growth and rapid deterioration of water quality (Cheng et al, 2001; Hoff & Snell, 2004; Wang et al, 2003). So the use of CME in combination with suspending yeast solution (SYS) may be able to enhance the reproduction of rotifers and maintain a better cultural environment (Rasdi et al, 2020). However, yeast‐fed rotifers usually have low nutritional value, and juvenile fish fed with yeast‐fed rotifers lead to low survival and growth due to nutritional deficiency (Eryalçın, 2019; Penglase et al, 2011).…”

To establish the optimal ratios of chicken manure extract (CME) and suspending yeast solution (SYS) for rearing rotifers, the population density, population growth rate, fatty acid compositions of rotifers and the unionized ammonia (NH 3 -N) and total phosphorus (TP) concentrations in cultured water under different ratios of CME and SYS (BG, EG1, EG2, EG3, EG4 and EG5) were investigated. The results showed that the population density and population growth rate of rotifers in EG2 (4 ml•L −1 CME: 0.3 ml•L −1 SYS) were the highest and reached 387.33 ± 12.34 and 0.57 ± 0.01 ind.•ml −1 , respectively. In addition, Pearson's correlation analysis indicated that the proportions of polyunsaturated fatty acids (PUFAs), n-3PUFAs, n-6PUFAs and long-chain PUFAs in rotifers were positively correlated with the content of CME (p < 0.05). Furthermore, NH 3 -N and TP in the cultured water decreased with the SYS contents increasing.Compared with EG5, the concentrations of NH 3 -N and TP in EG2 were reduced by 58.83 ± 0.05% and 72.52 ± 0.17%, respectively. These results indicated that both the population growth and fatty acid composition of rotifers, and the concentrations of NH 3 -N and TP in the cultured water were significantly affected by the ratios of CME and SYS. And EG2 was optimal for rearing the rotifer.
