“…Hence, a goal for maximum gain is offset by increased FCR. Thus, to maximize nutrient utilization, feeding below the maximum gain is recommended (Weldon et al 2021). In this experiment extruded feed demonstrated to have a combined effect with feeding frequency as interaction was observed in FCR and consumed feed.…”

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.

“…Por lo tanto, el objetivo de obtener la máxima ganancia se ve contrarrestado por un aumento del FCR. Por lo tanto, para maximizar la utilización de nutrientes, se recomienda alimentarlos por debajo de la ganancia máxima (Weldon et al, 2021).…”

“…La pandemia de COVID-19 también tuvo un impacto significativo en la cadena de suministro y la demanda de camarones, con interrupciones en la producción y el transporte. La alimentación es uno de los factores de producción más críticos en acuicultura, ya que representan el 40-60% de los costes operativos (Tan et al, 2005;Naylor et al, 2009;Tacon et al, 2013), por lo que su gestión adecuada es fundamental para maximizar las ganancias mediante la optimización de la eficiencia, un mayor crecimiento y la reducción de los impactos ambientales (Weldon et al, 2021).…”
