Special Issue Information

Dear Colleagues,

Recently, the Food and Agriculture Organization of the United Nations (FAO) called for a Blue Transformation (FAO, 2022) towards nutritious and sustainable aquatic food systems. To achieve this transformation, technical innovations and appropriate policies should go hand in hand to develop a more environmentally friendly, socially appropriate, nutritious, and healthy aquaculture food systems.

Various factors play a role, from better animals and more efficient rearing technology, to precise feeding, to more attention for biosecurity, environment, and governance. All this comes together in the choice of the production system used.

Aquatic food systems are currently characterized by a broad array of farmed organisms, environments and production systems. Some rely entirely on the natural foods produced in the environment (extractive systems, e.g., for seaweeds, bivalves, and carps), others are industrial with full control of the environmental parameters and feed inputs (such as recirculating aquaculture systems, RAS), and everything between these. Because of the growing concerns about the environmental burden of aquatic food systems, much attention has been given to the development of more ecological, nature-friendly, and community-based systems, such as integrated aquaculture systems (IMTA, IAA, Aquaponics), biofloc systems, and so on.

Aimed to share the knowledge needed for this Blue Transformation, Animals want to analyse the different aspects which can make future ecological aquaculture production systems more sustainable. In this context, we open this Special Issue and invite state-of-the-art papers on the following thematic areas:

  • Optimizing carrying capacity in open systems such as coasts, lakes, and reservoirs;
  • Identifying suitable areas for aquaculture operations; siting;
  • Waste-based feed resources, such as insects, microbial biomass, and yeast;
  • Species choices;
  • Circular aquaculture value chain systems;
  • Integrated systems (IMTA, IAA, Aquaponics, Biofloc) and their environmental impacts;
  • The environmental impacts of RAS and other closed-containment aquaculture systems, as well technological breakthroughs to improve their sustainability;
  • Restorative aquaculture and the preservation of natural habitats, efficient resource uses;
  • Biosecurity risks and control and health management;
  • Innovations using artificial intelligence technologies to improve animal welfare, health, and performance in aquaculture production systems;
  • Innovative governance regimes.

Aquaculture requires precise non-invasive methods for biomass estimation. This research validates a novel computer vision methodology that uses a signature function-based feature extraction algorithm combining statistical morphological analysis of the size and shape of fish and machine learning to improve the accuracy of biomass estimation in fishponds and is specifically applied to tilapia (Oreochromis niloticus). These features that are automatically extracted from images are put to the test against previously manually extracted features by comparing the results when applied to three common machine learning methods under two different lighting conditions. The dataset for this analysis encompasses 129 tilapia samples. The results give promising outcomes since the multilayer perceptron model shows robust performance, consistently demonstrating superior accuracy across different features and lighting conditions. The interpretable nature of the model, rooted in the statistical features of the signature function, could provide insights into the morphological and allometric changes at different developmental stages. A comparative analysis against existing literature underscores the competitiveness of the proposed methodology, pointing to advancements in precision, interpretability, and species versatility. This research contributes significantly to the field, accelerating the quest for non-invasive fish biometrics that can be generalized across various aquaculture species in different stages of development. In combination with detection, tracking, and posture recognition, deep learning methodologies such as the one provided in the latest studies could generate a powerful method for real-time fish morphology development, biomass estimation, and welfare monitoring, which are crucial for the effective management of fish farms.

The present study evaluated water quality, immune responses, nutritional condition, and production of Ompok pabda fry (0.29–0.31 g) reared in a Biofloc technology (BFT) system (C:N = 20:1; molasses as organic carbon source), compared to the traditional culture system (TS; farmer’s practice). The experiment had stocking densities for the treatments of 17 (TS1) and 22 (TS2), 17 (BFTS1), 22 (BFTS2), and 27 (BFTS3) fish/m2. The fishes were fed at 3–10% of their body weight, and reared in cemented tanks for 90 days. Regarding water quality, dissolved oxygen (DO), pH, and total ammonia nitrogen (TAN) levels varied significantly (p < 0.05) between the traditional and BFT tanks. The highest specific growth rate (SGR) was in the BFTS1-reared fishes (4.11 ± 0.17) but the lowest was in the TS2-fish (3.51 ± 0.05). The fish reared in BFT had higher levels of protein, lipids, polyunsaturated fatty acids, essential amino acids, hematocrit, and neutrophil than the fish reared in TS tanks. Moreover, 98.33% survival was recorded in the BFTS1 while 86.67% was in the TS2. The highest BCR was estimated for the BFTS2 (1.22). Taking into account FCR and BCR values, a stocking density of 22 fry/m2 is likely practicable for an O. pabda BFT system. Full article

Given the scarcity of water and land resources, coupled with the competitive nature of aquaculture, the long-term viability of this industry will depend on strategies for vertical development. This involves enhancing production environments, increasing productivity, and advancing aquaculture technologies. The use of biofloc technology offers a potential solution to mitigate the adverse environmental impacts and the heavy reliance on fishmeal in the aquaculture sector. This method is designed to effectively assimilate inorganic nitrogen found in aquaculture wastewater, thereby enhancing water quality. Additionally, this process produces microbial protein, which can serve as a viable supplemental feed for aquatic animals. Furthermore, this technique has the potential to reduce the feed conversion ratio, thereby lowering overall production costs. This article provides an overview of the evolving field of biofloc system technology within aquaculture. In this study, we will examine the historical development and various types of biofloc systems, as well as the factors that influence their effectiveness. Finally, we will explore the economic potential of implementing biofloc systems in aquaculture. Full article
