“…The bulk density obtained in this study for both DFM-based-and DBSFLbased extruded pellets is a factor of barrel temperature and adequate moisture content of the blend. Although values between DFM-based-and DBSFL-based extruded pellets were significantly different, they are however similar to those reported by [38] who worked on the effects of Clostridium autoethanogenum protein inclusion levels and processing parameters on the physical properties of low-starch extruded floating feed. Our findings further reveal a phenomenon that shows an inverse relationship between bulk density on the one hand and expansion ratio and floatability on the other hand.…”

“…In this study, the high moisture content of the melted blend resulted in a higher water absorption index and lower water solubility index of extrudates. This phenomenon may be due to the gelatinization of starch at a higher moisture content of melted blend rather than dextrinization reported by Ma et al [38]. Ma et al [38] worked on the effects of Clostridium autoethanogenum protein inclusion levels and processing parameters on the physical properties of low-starch extruded floating feed at low moisture blends content.…”

A twin-screw hot extrusion processing study was performed using defatted black soldier fly larvae (DBSFL) meal as a complete substitute for Danish fishmeal (DFM) in the production of aqua-feed. The defatting process of full-fat black soldier fly larvae (BSFL) reduced its crude fat content by 60%. This was mixed together with other ingredients (soybean meal, cassava flour, vitamin and mineral mix, vitamin C, and anti-mold) to formulate a fish diet containing 40% crude protein. The moisture content of the formulated mixture was 300 g/kg prior to extrusion. The extruder feeder motor speed, main motor speed and cutter motor speed were set at 210, 300 and 700 rpm respectively. Results show a significant increase (P < 0.05) in the crude protein (CP) content of DBSFL meal when compared with full-fat BSFL meal with values of 51.83 ± 0.03 and 47.44 ± 0.2 respectively. However, CP values of the DBSFL meal were significantly (P < 0.05) lower than those obtained for DFM with values of 51.83 ± 0.03 and 72.13 ± 0.18 respectively. The physical properties of extruded floating pellets showed significant differences (P < 0.05) between DFM-based extrudates and DBSFL-based extrudates in terms of expansion ratio (ER), sinking velocity (SV), Unit density (UD), bulk density (BD), and pellet durability. However, no significant differences (P > 0.05) were observed in terms of floatability, moisture content and water absorption index (WAI). It was concluded that, the extrusion of DBSFL-based pellets compared favourably with DFM-based extruded pellets thus, the processing of full-fat BSFL into DBSFL meal makes the latter suitable for extrusion purposes and appropriate in the production of good quality floating feed pellets desired by fish farmers and suitable for feeding fish.

“…In addition, compared with low‐temperature steam‐dried FM, C. autoethanogenum meal has a higher water‐holding capacity. Ma and his colleague also reported that the addition of C. autoethanogenum meal to the diet enhanced the oil absorption capacity and water stability of the feeds 183 . Currently, an increasing number of studies have addressed variations in the physical properties of feeds after FM substitution, including hardness, sinking velocity, and water solubility, and efforts have been paid to adjust processing parameters based on these results, enabling a more accurate, easier and less wasteful feeding 184 …”

Pacific white shrimp (Litopenaeus vannamei), the most cultured crustacean in the world, has become one of the key species in the international aquatic trade accounting for 11.96% of the total aquaculture production value in 2020. The development of the aquafeed industry, especially the large‐scale use of fish meal (FM) and fish oil, contributed to promoting the expansion of shrimp production. However, the supply of FM has fluctuated at about 5 million tons per year affected by the El Nino during the last decades. This finite supply in combination with continued demand contributes to high prices, prompting the development and use of alternative protein sources. This review contributes to the development of appropriate FM replacement strategies in shrimp feed and summarises the status of research on alternative protein sources, including plant, animal and single‐cell proteins in commercial feeds for Pacific white shrimp. Furthermore, several key aspects of nutritional balances were mentioned including amino acid profiles, fatty acid nutrients and trace elements in low FM diets as well as some easily overlooked concepts that deserve attention such as epigenetics, feed processing characteristics, animal growth stages, and shrimp species improvement. Also, the prospects of future research are proposed including the application of advanced technologies (16S rRNA sequencing, transcriptomics, proteomics and metabolomics), developments in the new feed additives, along with the optimisation of new protein sources and the establishment of a precise nutritional programming for shrimp.

Aquaculture has been the fastest‐growing food production sector and is considered to be so in the future. However, aquaculture feed is heavily dependent on wild‐captured forage fish, which is unsustainable, costly and non‐ecofriendly. Hence, the development of sustainable, eco‐friendly, cost‐effective and nutrient‐balanced novel fishmeal alternatives is critical to satisfying the forecasted expansion of aquaculture. Among fishmeal alternatives, attention to one‐carbon gas protein (C1GP) has reached an unprecedented level recently. The C1GP is produced through the fermentation of certain unique microorganisms by utilizing the substrates from C1‐related industrial exhaust gases, such as CH4, CO and CO2, which take much less time, land, water and resources, remove greenhouse gases and waste materials, and offer sustainable protein sources. These C1GP products, either as fishmeal or soybean meal alternatives, have been successfully used in fish and shrimp diets. This review introduces the latest research progress on microorganisms, protein production technology, nutrition and products using C1 gases as substrate, as well as their application in aquafeed. With the rapid development of synthetic biotechnology and engineering technology, it will become an important development field in the future in the construction of new strains and gas fermentation technology with high transformation efficiency, wide adaptation and abundant nutrients for the development of new ingredients for aquaculture.
