- Shrimp processing waste in aquaculture feed: nutritional value, applications, challenges, and prospectsPublication . Eggink, Kylian Manon; Goncalves, Renata; Skov, Peter VilhelmThe global shrimp processing industry generates substantial amounts of solid waste (head, abdominal exoskeleton, and tail), with a considerable part currently being disposed of in landfills. It holds significant potential as an alternative ingredient in aquaculture feed due to its relatively high crude protein content, balanced amino acid profile, and presence of bioactive compounds. However, one of the main challenges with shrimp processing waste is its rapid spoilage. Consequently, shrimp solid processing waste must undergo further refinement to produce shrimp-derived products suitable as aquaculture feed ingredients, such as meal, hydrolysate, or silage. This literature review describes the nutritional value, applications, challenges, and prospects of these shrimp-derived products in aquaculture feed. Among the investigated shrimp-derived products, shrimp hydrolysate has the highest nutritional value considering the high crude protein content, balanced amino acid profile, low chitin content, and low ash content. However, producing shrimp hydrolysate requires extensive processing, which can be costly, limiting its applications to high-value aquaculture species. On the other hand, shrimp meal and shrimp silage, which require less energy-intensive processing, may be more suitable for lower-value aquaculture species that naturally consume feeds high in ash and chitin. The prospects for using shrimp-derived products in aquafeed are promising, with advances in processing technologies showing potential to reduce costs, improve nutritional value, and enhance product quality and safety. Ultimately, shrimp-derived products could replace current aquafeed ingredients while simultaneously utilizing current shrimp solid waste streams, provided that quality and safety measures are carefully considered.
- Strategy in sport performance: how training programmes could shape dynamic, adaptive intentional processes in performersPublication . Pereira, Elsa; Carvalho, João; Davids, Keith; Araújo, DuarteRecent developments in sports science have indicated that traditional models for planning training programs typically lack coherence for developing the complexity of adaptive processes that emerge from and are invited by training and competition. Here, we argue that the strategic management of training programs for sports performance development may emerge from continuous interactions between individuals in a non-linear transformative causality, displaying transactional intentionality. Based on the understanding and application of theories in complexity sciences, and from the perspective of the ecological dynamics of human behavior, it is intended to contribute to the strategic process that underlies the development of sports performance. Here, we seek to articulate how the strategic process that underlies sports performance development is based on an "educated intentionality" that guides the coaches' actions (e.g., problem-solving, decision-making, planning, and organization). This approach requires a co-evolving design process and decision-making in sports performance development so that athletes can implement adaptive behaviors in competitive contexts.
