“…These results were in accordance with Soares, Peixoto, Galkanda‐Arachchige, et al. (2021), who observed a significantly higher PDI for extruded shrimp feed (97%) than pelleted shrimp feed (92%) used during their trial. Additionally, these authors reported that the extruded diet had significantly higher hardness than pelleted diet; and suggested that the diet hardness is closely related with the ingredients’ composition, extrusion moisture, cut and temperature adjustments.…”

“…Hence, these authors concluded that there were no indications of the feed with no fishmeal being rejected or being less palatable. To improve the palatability of the soybean‐based diets, Soares et al., (2021) suggested that low addition level (10 g/kg) of krill meal, krill oil or fish hydrolysate to a soy‐based diet can improve food consumption and stimulate feeding activity of P . vannamei .…”

Pacific white shrimp (Penaeus vannamei) farming is one of the major aquaculture activities in many countries contributing 53% of the global shrimp production in 2016 (FAO 2018). In semi-intensive and intensive shrimp farming, artificial feed is the main nutrient source, which must be both nutritionally and economically adequate for the culture system. Feed represents up to 60% of total production costs (Rego et al., 2017); therefore, the quality of the feed is important in shrimp aquaculture. Protein is the most critical ingredient in shrimp diets from standpoint of cost and growth response (Sánchez-Muros et al., 2020).Due to desirable characteristics, such as high-quality protein, amino acid profile, palatability, lipid content, high digestibility and nutrient content, fishmeal has been the most important protein source

“…Extrusion processing has improved growth and feed utilization of rainbow trout (Glencross et al 2011); silver perch (Booth et al 2002) (Tacon 2003;Chamberlain 2004; Molina-Poveda and Espinoza-Ortega 2019). However, basically, similar growth performance was found in channel cat sh (Xu et al 2017), P. monodon, and L. vannamei, respectively (Rout and Bandyopadhyay 1999;Soares et al 2021b). Therefore, the objective of this study was to determine the effect of feeding frequency with extruded or steam-cooked pellets on weight gain, feed conversion ratio, survival, and water quality for juvenile Paci c white shrimp (Litopenaeus vannamei).…”

Feeding strategies have a significant impact on growth and water quality in shrimp farming. Feed management also affects health, survival, and shrimp yields. All these factors contribute to production cost-effectiveness and commercial shrimp industry sustainability. The effect of feeding frequency and two aquafeed cooking processes (extrusion and pelleting) on shrimp performance and water quality parameters were studied under controlled conditions in a 60-day trial with juvenile Litopenaeus vannamei fed once (10:00 h); twice (10:00 h, 12:00 h); four (10:00 h, 12:00 h, 15:00 h, 18:00 h); and six (10:00 h, 12:00 h, 15:00 h, 18:00 h, 21:00 h, 24:00 h) times/day. No statistical differences (p > 0.05) in growth rate, survival, nor feed efficiency were observed within pelleted feed treatments at any of the frequencies tested. Growth rate was significantly higher (p < 0.05) with extruded feed when administered once or twice in daylight (10:00–12:00 h). However, at such frequencies, growth was achieved at the cost of water quality and feed conversion ratio. At higher frequencies (six times a day) with extruded diets, the results in water quality suggest a reduction in total ammonia nitrogen and nitrite-nitrogen levels as frequency increased. The outcomes of this study suggest that extruded feed with daylight feeding has the potential to improve growth rate, and an increased frequency could represent a suitable strategy to preserve water quality. This study is the first to show that the extrusion process improves water quality; thus, extruded feeds could reduce effluent pollution impact and improve shrimp farming sustainability.

“…Such engineering systems are highly complex but offer a substantial level of control over the pellet‐forming process, enabling the user to have significant control over pellet density, durability, and oil infusion capacities (Sørensen, 2012). Shrimp feeds, despite still being predominantly pelleted, are beginning to emerge as extruded products through some companies (Obaldo et al, 2000; Soares et al, 2021). In the developing world, there is still widespread use of pelleting, mash, and trash fish feeding.…”

Over the past 20 years, substantial progress has been made in improving feeds and feeding technologies for most aquaculture species. Notable improvements in feed conversion efficiency (through a better understanding of requirements and improved feed management) and ingredient sustainability (through increased capability to use a wider range of ingredients) have been achieved. While advances have been made in understanding the requirements of many of the main aquaculture species, there is still much to be done in defining requirements, especially for many of the species being farmed in the developing world. Gains in the efficiency of feeds are slowing for developed species, but potential gains are still appreciable for less developed species. There is a growing need to more precisely prescribe the required levels of essential nutrients and various additives in the diet based on age, genotype, environment, and immune status to deliver a “precision nutrition” approach to farming aquaculture species. There is still further need to diversify our ingredient options to provide greater resilience, as the sustainability of different feed ingredient sources, including possible climate change impacts, is becoming a growing issue. There is a growing demand for biocircularity in our feed ingredient supply chains. Ultimately, what is needed to sustain future feed ingredient needs are sustainable sources of cost‐effective protein, some essential amino acid additives, some omega‐3 fatty acid resources, and various minerals and vitamin additives. The increasing use of new and varied resources will ensure that food safety remains an important issue throughout the world. Feed manufacturing has evolved from a simplistic exercise to a highly complex science with state‐of‐the‐art engineering, but its application is not consistent across all sectors, as there is still widespread use of pelleting, mash, and trash fish feeding in the developing world. Similarly, feed management has also dichotomized between the developed and developing world, with a high reliance on manual skilled labor in the developing world, whereas more advanced aquaculture systems are becoming increasingly reliant on automated computer‐controlled feeding systems.
