Special Issue Information

Dear Colleagues,

Fisheries and aquaculture are important sectors for food, welfare and the economy of many regions, as well as for the environmental state of seas and oceans. Both activities are currently at a time of critical analysis of their impacts and a debate on the necessary technical, commercial and management changes to ensure their sustainability. The objective of this Special Issue is to critically analyze the current situation of fisheries and aquaculture, as well as to address various debates and initiatives that are leading to significant innovations in both sectors. Critical analyses of the economic, social and environmental impacts of fisheries and aquaculture are welcome, as well as analyses that propose new alternative forms of management, production, diversification and marketing. We are looking for papers from any region of the world and from different methodologies to contribute novelties to the current debate on where fisheries and aquaculture are and where they should be heading.

Understanding the spatial patterns of neon flying squid is important for the monitoring and management of fishery resources. Mesoscale eddies and the Kuroshio Extension play important roles in the variation of the fishing ground of Ommastrephes bartramii. However, the way in which eddies and the Kuroshio influence the distribution of Ommastrephes bartramii requires further understanding. In this study, the spatial variation in the distribution of fishing activity and the change of fishing ground gravity of squid were analyzed using automatic identification system (AIS) data. There is a positive correlation between the fishing ground gravity in latitudinal direction and Kuroshio Extension indicators based on the high-frequency eddy kinetic energy (EKE), which describes the Kuroshio variations. Furthermore, the Kuroshio Extension indicators show a positive relationship with the number of the eddies generated in the fishing ground. The results suggest that the changes in the dynamics of SST anomalies could be influenced by eddy-shedding processes in the upstream KE and then alter the distribution of the fishing ground for Ommastrephes bartramii. The Kuroshio index (mean high-frequency eddy kinetic energy between 32° and 37° N, 142° and 149° E) can be used as a good indicator of Kuroshio extension variations to investigate the squid fishing ground in the Kuroshio–Oyashio transition area.

The fishing sector is facing major economic and environmental challenges worldwide. However, at least in developed countries, it is also undergoing a major social crisis. This research has tried to quantify and validate this subjective feeling of deep crisis, based on objective and quantitative data referring to the Spanish Mediterranean. Indeed, the results show alarming data. Different scattered databases have been analyzed and it has been exposed that in only 15 years the number of vessels, power and tonnage has decreased by about 40%; as for fishermen, their number has decreased by about 30%, also revealing a serious problem of generational replacement, since in only 10 years, the average age of fishermen has increased by 3 years. A simple linear regression model shows that this downward trend in the number of boats and fishermen will continue at least in the short term. The data obtained invite a deep reflection on the future or even the very survival of fishing in the Spanish Mediterranean in the medium term. This reflection is not limited to this specific area but can be extrapolated to many other fishing areas. Full article

The classical cumulative damage method based on the S-N curve or crack growth model is unrealistic for predicting the lifetime of fishing nets under actual service conditions. In this paper, a novel and practical method based on the wave return period model and residual strength model is presented to estimate the dynamic lifetime of fishing nets under different numbers of damaged netting bars. The tension distribution rules, dangerous breakage zones, damage-developing-paths, and breakage patterns of two types of tensioned nettings are calculated using the commercial software RIFLEX. The most dangerous breakage zones appear in the areas near the midpoint of the upper fixing boundary side for both square mesh and diamond mesh netting. The tension distribution of diamond mesh netting is more uniform than that of square mesh netting, which implies that diamond mesh is more durable than square mesh. The dynamic lifetime prediction shows that the netting will be damaged more and more quickly after its initial fracture. Relative dynamic lifetime curves provide a way to forecast the subsequent damage time according to the net’s initial fracture lifetime. Adjusting the installation angle of the polygon cage can reduce the maximum tension of a fishing net under the wave load, thus increasing the lifetime of the fishing net. Full article

In the cultivation of barramundi Lates calcarifer, one of the key factors is developing new commercial feeds that are nutritionally adequate and attractive to fish. The sensory quality of feeds can be improved by taste stimulants. The aim of the present study is to examine the taste attractiveness of 21 free L-amino acids and 4 basic taste substances (0.1–0.001 M). The feeding behavior that accompanied the orosensory testing of feed is also studied. Agar pellets flavored with each taste substance were individually offered to barramundi juveniles (5–9 cm, 4–10 g). Citric acid, cysteine, and alanine were palatable; sucrose and 7 amino acids had an aversive taste; sodium chloride, calcium chloride, and 12 amino acids did not influence the consumption of pellets. Taste preferences for amino acids are positively correlated in 6 out of 21 fish species, which confirms high species specificity of taste preferences in fishes. Barramundi often make repeated grasps and rejections of pellets regardless of their palatability, which led to the destruction of pellets in up to 50% of trials. When swallowing, fish retain pellets several times longer, and pellet fragmentation occurs more often, than in the case of final refusal of pellets. The data presented here can be used to improve the cultivation of barramundi. Full article

The world population is expected to grow to around 9 billion by 2050. The growing need for foods with high protein levels makes aquaculture one of the fastest-growing food industries in the world. Some challenges of fishing production are related to obsolete aquaculture techniques, overexploitation of marine species, and lack of water quality control. This research systematically analyzes aquaculture technologies, such as sensors, artificial intelligence (AI), and image processing. Through the systematic PRISMA process, 753 investigations published from 2012 to 2023 were analyzed based on a search in Scopus and Web of Science. It revealed a significant 70.5% increase in the number of articles published compared to the previous year, indicating a growing interest in this field. The results indicate that current aquaculture technologies are water monitoring sensors, AI methodologies such as K-means, and contour segmentation for computer vision. Also, it is reported that K means technologies offer an efficiency from 95% to 98%. These methods allow decisions based on data patterns and aquaculture insights. Improving aquaculture methodologies will allow adequate management of economic and environmental resources to promote fishing and satisfy nutritional needs. Full article

Automated monitoring and analysis of fish’s growth status and behaviors can help scientific aquaculture management and reduce severe losses due to diseases or overfeeding. With developments in machine vision and deep learning (DL) techniques, DL-based object detection techniques have been extensively applied in aquaculture with the advantage of simultaneously classifying and localizing fish of interest in images. This study reviews the relevant research status of DL-based object detection techniques in fish counting, body length measurement, and individual behavior analysis in aquaculture. The research status is summarized from two aspects: image and video analysis. Moreover, the relevant technical details of DL-based object detection techniques applied to aquaculture are also summarized, including the dataset, image preprocessing methods, typical DL-based object detection algorithms, and evaluation metrics. Finally, the challenges and potential trends of DL-based object detection techniques in aquaculture are concluded and discussed. The review shows that generic DL-based object detection architectures have played important roles in aquaculture. Full article
