“…30% replacement resulted in depressed ETS activity in both species, decreased activities of CS and HOAD in Ostrea edulis, and a lower condition index in Ruditapes decussatus. Encouraging results have been reported by many authors when using manipulated yeasts as an algal substitute [3,6] or by using efficiently digested mutant yeast cells [13], reaching substitution percentages of 50-80%.…”

“…Fishmeal is a good feedstock enriched with protein, but its high cost seriously limits its wide use in aquaculture. To provide aquatic animals with affordable diets, previous studies focused on the exploration of low‐cost biomass with high protein content 40,41 . Algal biomass is regarded as an affordable and high‐value feedstock that can be widely used to produce fish diet 42 .…”

BACKGROUND: The discharge of food waste and eutrophication in aquaculture could cause environmental pollution and ecological disasters in the hydrosphere. Herein, a novel model of growing microalgae to recover nutrients from food waste and produce feed substitute for aquaculture is proposed. RESULTS: This study developed different methods to pretreat soybean fermentation effluent (SFE) and assessed the contribution of algal growth to nutrient recovery from SFE. Particularly, change of bacterial community was analyzed to explore the interaction between microalgae and bacteria in SFE remediation. In addition, the inclusion level of microalgae in fish diet was optimized and the effect of fresh microalgae on the aquaculture environment was studied. The results showed that unsterilized SFE with appropriate dilution is favorable for microalgal growth and biomass accumulation. Interaction between microalgae and acidogenic bacteria, including Prevotella sp., Acidaminococcus sp. and Lactobacillus sp., favored nutrient recovery from SFE. Removal efficiency of chemical oxygen demand, total nitrogen, total phosphorus and total ammonia‐nitrogen in SFE reached 95.66%, 35.35%, 57.70% and 42.21%, respectively. As the optimal inclusion level of microalgae in fish diet was set as 25%, body length and weight of Micropterus salmoides increased by 13.85 mm and 1.73 g in 44‐day culture. It was also found that fresh microalgae added in fish diet could effectively keep the ammonia concentration in aquaculture system at a lower level. CONCLUSION: The implementation of this model will be of importance to circular economies integrating food waste remediation and eco‐friendly aquaculture. © 2021 Society of Chemical Industry (SCI).

“…Partial replacement of live microalgae using diferent types of formulated diets has been reported for facilitating the aquaculture of a number of species of bivalves. For example, yeast-based diets [21], lipid emulsion [22], microcapsule [23], bacteria [24], and microalgal pastes [25,26] have been used to partially substitute live microalgae for rearing juvenile shellfsh. For example, a replacement of 20% of the dried microalgae Tetraselmis suecica, 80% of yeast and up to 81% of mixed microcapsules and yeast has been found to be a satisfactory diet for juvenile oysters (Crassostrea gigas and Ostrea edulis) and the clams (Mercenaria mercenaria and Ruditapes philippinarum) [15].…”

The nursery culture of bivalves typically relies on the feeding of costly live microalgae, while the use of natural sources of phytoplankton for feed is uncertain due to their variable quality and abundance. Replacement diets have been applied in bivalve nursery culture to replace live microalgae with varying success. This study investigated the potential use of two concentrated microalgal diets at a range of levels of substitution with live microalgae. Shellfish Diet 1800® (called SD) and LPB™ Frozen Shellfish Diet® (called LPB) were fed to juvenile green-lipped mussels (Perna canaliculus) at five levels of substitution for live microalgae (i.e., 0, 25, 50, 75, and 100%) for 27 days. The mortality of mussels fed with 100% LPB replacement was significantly higher than the mortality of mussels fed at the lower levels of replacement, i.e., 0 and 25%. The overall final size of spat tended to decrease with the increasing level replacement of live microalgae. Proximate analysis (i.e., crude ash-free dry weight, crude protein, crude lipid, and carbohydrate) showed that only the proportion of carbohydrate content of spat was influenced by feeding treatments, with the mean total carbohydrate content of mussels tending to decrease with increasing levels of replacement of live microalgae. The results indicate that both concentrated microalgal feeds (SD and LPB) are effective at replacing live microalgae by up to 50% without compromising the survival and nutritional profile (AFDW, protein, lipid, and carbohydrate content) of juvenile green-lipped mussels and are therefore a useful resource for improving the efficiency of production.
