The incorporation of high-energy diets in the aquaculture industry has become a common practice to enhance growth and productivity. However, recent studies have shed light on the potential risks associated with excessive lipid levels in fish diets. Understanding and mitigating these effects is crucial to ensure the health and economic viability of farmed fish.
Understanding the Risks:
While moderate levels of lipids can boost fish performance in the short term, excessive levels can lead to a myriad of undesired impacts. These include excessive growth without skeletal support, impaired liver function, diminished antioxidant capacity, and weakened immune function. Moreover, these diets have been linked to lipid accumulation in viscera, endoplasmic reticulum stress, and suppression of autophagy in fish liver. Additionally, they can disrupt the intestinal barrier, triggering inflammation, metabolic disorders, oxidative stress, and microbiota imbalance.
Mitigation Strategies:
Fortunately, there are several approaches that can help mitigate the adverse effects of these diets on farmed fish. Dietary manipulation stands out as a key strategy, involving adjustments in the composition of fish diets to alleviate the negative impacts of excessive lipid intake. This includes reducing blood lipid levels, attenuating oxidative stress, and improving immune function and antioxidant activity in fish.
Role of Feed Additives:
In addition to dietary adjustments, the use of feed additives has shown promising results in mitigating the risks associated with high-lipid diets. Supplements such as herbs, acids, minerals, and certain vitamins have been found to modulate lipid metabolism and enhance the endogenous antioxidant defense mechanism in fish. These additives play a crucial role in altering cellular signaling activities, thus offering indirect protection against the adverse effects of high-lipid diets.
