“…Using high‐precision imaging sonar and underwater cameras to simultaneously record images, or using local counting regression networks, can improve on this problem 38,138 . Finally, most of the existing studies are aimed at wild fisheries, only a few of them are used in aquaculture ponds and offshore net cage culture, and some of them are still in the laboratory stage 139 . Therefore, accelerating the development of small imaging sonar equipment matching circulating aquaculture and pond aquaculture and attracting more scholars' attention to the development of intelligent algorithms for acoustic image processing are effective ways to promote the wide application of acoustic technology in aquaculture.…”

Acoustic technology has great application prospects in aquaculture. In particular, two indispensable, critical technologies for the future aquaculture industry are multi‐sensor acquisition that can achieve multi‐scale information fusion, collection and establishment of a global acoustic fish database and highly developed deep learning intelligent algorithms that can establish a correlation mechanism between fish acoustic and behaviour characteristics. Acoustic technology offers remarkable advantages in large and turbid water bodies for studying spatial and temporal distribution patterns of aquatic organism populations, developing on‐demand feeding systems and estimating biomass. This article reviews the development of acoustic technology and its application in aquaculture over the last 30 years. It further analyses, in detail, the advantages and disadvantages of acoustic technology in evaluating aquatic organism biomass and morphological and physical indicators, aquatic organism behaviour and welfare improvement. Challenges of acoustic technology in acquiring dynamic target data accurately, building a global acoustic fish database and establishing connections between fish behaviour and acoustic characteristics are also discussed. In brief, this article aims to help researchers and practitioners better understand the current state‐of‐the‐art acoustic technologies, which can provide strong support for smart aquaculture applications.

“…Fish biomass, on the other hand, is the total mass of fish in a given area, often expressed as the weight of fish per unit area. Acoustic technology can be used to estimate fish biomass by measuring the number and size of fish in a given area (Orduna et al, 2021). This information can then be used to calculate the total weight of fish in that area.…”

Sound propagates effectively through the water column, establishing hydroacoustic technology as a premier method for underwater exploration, including the mapping of aquatic ecological resources. While the fisheries sector is considered pivotal in aquatic resource studies, mapping fisheries remains challenging due to the distinct distribution patterns exhibited by fish within the water column, which are intricately linked to their habitat preferences. In this study, the hydroacoustic method was employed to analyze the distribution of fish in the waters surrounding Lancang Island, Seribu Islands, Jakarta. This analysis utilized the target strength (TS) value alongside oceanographic parameters. Acoustic data was collected using a 200 kHz single beam echosounder based on parallel transects encircling the waters of Lancang Island. CTD was utilized to collect oceanographic data to acquire temperature and salinity profiles within the water column. The acoustic data processing was conducted using the post-processing software SONAR 5-pro. The analysis was performed based on acoustic cells, obtained by dividing segments every 100 m horizontally and layers every 5 m vertically, thereby obtaining the Target Strength per cell (TSc) and volume backscattering strength (SV) values from each cell. The results showed that the highest average TSc value was found in the depth range of 26-31 m at -46.98 dB, and the highest SED biomass was also found in the same depth range at 26.6 kg.ha-1. Based on the analysis of water temperature and salinity, it was found that these factors significantly influence the distribution of fish in the waters of Lancang Island (R-square= 0.1276 and P< 0.05). This finding also indicates the presence of other parameters affecting fish distribution in Lancang waters, with the type of substrate and habitat emerging as potential determining factors, notably in coral reef environments.
