Special Issue Information

Dear Colleagues,

Aquaculture is the fastest growing food production industry today, with an outstanding contribution to one of the greatest global challenges, which is to feed the 9.6 billion people who will inhabit the world by the year 2050. This fact makes the current reliance of the aquaculture industry on feeds produced from wild-caught fish unsustainable. Therefore, and despite the important efforts focused on finding and testing alternative ingredients able to reduce the dependency on regular ingredients carried out, developing sustainable and nutritious aquafeeds still remains one of the greatest challenges in aquaculture.

Considering the success of our previous Special Issue, we are pleased to launch "Innovative and Sustainable Ingredients for Redefining Aquaculture Feeds: Second Edition". The aim of this Special Issue is to publish high-quality papers concerning innovative and sustainable ingredients that not only provide an adequate nutritional value, but are also available at an industrial scale, as well as economically affordable. Therefore, we invite the submission of recent findings, in the form of original research articles or reviews, on fish nutrition oriented toward improving the growth and general status of the animals as well as recent findings about biotechnological treatment to improve their nutrient quality and bioavailability for the optimization of feed and raw materials.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Tenebrio molitor (TM) meal is a potential alternative ingredient to plant and fishmeal in aquafeeds due to its high protein content, digestibility, and low environmental impact. However, its low n-3 PUFA (EPA and DHA) content represents one of its main limitations. This study evaluated the effects of replacing fishmeal and plant-derived ingredients (plant proteins and soybean oil) with full-fat TM meal on the growth performance and lipid composition of tissues in juvenile European seabass (Dicentrarchus labrax). Four experimental diets, including 5–10% TM for replacing fishmeal and soybean oil (FM5 and FM10) and 10–20% TM for substituting plant protein ingredients and soybean oil (PI10 and PI20), were tested over 49 days against a control diet (CT). Fish fed on PI20 exhibited the highest growth performance (final weight: 49.73 g and SGR: 1.78% day−1) compared to fish fed on FM (final weight: 47.0 g and SGR: 1.62% day−1) and CT (final weight: 48.45 g and SGR: 1.71% day−1). In general, the diets containing TM modulated the lipid profile in fish tissues by reducing the liver lipid content and muscle triglycerides and increasing the n-3/n-6 ratio compared to the CT diet. However, the most effective approach for modulating those parameters seems to be using the TM meal for replacing the plant ingredients instead of substituting fishmeal. Moreover, this feeding strategy, demonstrated to be useful for promoting the growth of fish owing to the use of the TM meal for replacing fishmeal, resulted in a slight reduction in the final weight of the fish.
