In modern aquaculture, water-fed systems are gaining ground. thanks to its potential for automate the nutrition process and guarantee a efficient supply in increasingly complex facilities.
However, its actual implementation involves technological challenges yet to be resolved., since the path that the feed travels from the silo to the fish is conditioned by numerous factors that can affect the quality and efficiency of the process.
Waterborne systems: advantages and added complexity
Specialized companies and researchers in the sector emphasize that Water supply systems are being integrated into both open and closed systems. aquaculture, seeking to optimize resources and reduce human intervention. The main objective is that the food reaches the fish in perfect condition: solid, with high nutritional content and ready to be consumed at the desired depth and location.
However, this seemingly simple route is influenced by the pressure of the pumps, the length of the hoses and the physical characteristics of the food., which can cause changes in the density or integrity of the pellets during the journey.
The role of pressure and depth in feeding
One of the main challenges facing waterborne nutrition is the effect of pressure on food behaviorTo transport the pellets through the pipes and deposit them underwater, pumps exert pressure that can cause the feed to absorb water, increasing its weight and accelerating its sinking.
As the system deposits food deeperAs ambient pressure continues to increase, it further affects the pellet's buoyancy. This poses a significant challenge for maintaining slow or floating feed, as it can sink faster than expected, making it difficult for fish to consume it at its optimal point.
Therefore, It is essential to carefully control the pressure parameters and know how they affect each type of food. to adapt the process and avoid nutritional losses or inadequate supply.
Sampling and quality control
Evaluating how food behaves in these systems is not a simple task.Analyzing pellets at the silo outlet or at the water surface is not sufficient, as transport at different depths and varying conditions can significantly alter their structure and composition.
Sampling is usually done under special conditions, for example 20 or 30 meters underwater., where variations are detected that are not perceived in the upper part of the system. Furthermore, the pressure and prolonged passage of the pellet through the water can alter the texture, sinking speed, and nutrient availability.
Therefore, Leading companies are committed to continuous research and analysis both in laboratory and real-life conditions, integrating simulations and sample collection in different environments to obtain a complete view.
Innovation and research for the future of aquaculture feed
Adapting water feeding to the needs of each species, cultivation phase or production system requires deep technical knowledge and constant innovation. Thus, new feed formulations, pumping technologies and hose materials are being experimented with to ensure that the food arrives in optimal conditions and without waste.
Only with extensive research and continuous learning will it be possible to solve today's challenges., achieving a more efficient and sustainable aquaculture capable of guaranteeing fish welfare.
The development of waterborne feeding is marking a significant evolution in the aquaculture sector, although it still requires effort and refinement to address all critical issues. Maintaining a balance between efficiency, parameter control, and animal nutrition will be key in future research.
