“…One other route for prevention is the implementation of risk management plans specifically for this disease. A work published recently by Gutiérrez-Estrada et al 236 describes the development of software and an app that can be used by the producers to predict amyloodiniosis outbreaks. This risk management software is based on environmental parameters and fish behavioural factors communicated by the producers and was statistically sensitive to the occurrence of A. ocellatum outbreaks in sea bream (Sparus aurata) and sea bass (Dicentrarchus labrax) rearing ponds.…”

Fish ectoparasites are one of the pathogens groups that pose great concern to the aquaculture industry. The dinoflagellate Amyloodinium ocellatum is responsible for amyloodiniosis, a parasitological disease with a strong economic impact in temperate and warm water aquaculture, mainly in earthen pond semi‐intensive systems. Amyloodiniosis represents one of the most important bottlenecks for aquaculture and, with the predictable expansion of the area of influence of this parasite to higher latitudes due to global warming it might also be a threat to other aquaculture species that are not yet parasitized by A. ocellatum. This review made a compilation of the existing knowledge about this parasite and the disease associated with it. It was noticed that, except from the life cycle characterisation, detection methods, histopathological analysis, and treatments, there are still a lot of areas that need a further investment in research. Areas like parasite–host interactions, epidemiological models, taxonomy, host physiological responses to parasitism, and genome sequencing, amongst others, can contribute to a better understanding of this disease. These proposed approaches and routes of investigation will enhance and contribute to a more standardised knowledge, creating the opportunity for a better understanding of amyloodiniosis impacts on fish and contributing for the development of new tools against A. ocellatum, that may reduce fish mortality in aquaculture production due to amyloodiniosis outbreaks.

“…Recently, significant attention has been directed toward the modernization of aquaculture, particularly in the development of methodologies for biomass and population growth estimation [9,10], as well as the measurement of physical-chemical parameters that characterize the aquatic ecosystem [11]. Small-scale ROV systems have proven to be valuable tools for these applications due to their versatility and ability to maneuver effectively within confined spaces.…”

This article introduces a control architecture designed for the development of Hybrid Remotely Operated Underwater Vehicles. The term ”Hybrid” characterizes Remotely Operated systems capable of autonomously executing specific operations. The presented architecture maintains teleoperation capabilities while enabling two fully autonomous applications. The approach emphasizes the implementation of reactive navigation by exclusively utilizing data from a Mechanical Scanned Imaging Sonar for control decisions. This mandates the control system to solely react to data derived from the vehicle’s environment, without considering other positioning information or state estimation. The study involves transforming a small-scale commercial Remotely Operated Underwater Vehicle into a hybrid system without structural modifications, and details the development of an intermediate Operational Control Layer responsible for sensor data processing and task execution control. Two practical applications, inspired by tasks common in natural or open-water aquaculture farms, are explored: one for conducting transects, facilitating monitoring and maintenance operations, and another for navigating toward an object for inspection purposes. Experimental results validate the feasibility and effectiveness of the authors’ hypotheses. This approach expands the potential applications of underwater vehicles and facilitates the development of Hybrid Remotely Operated Underwater Vehicles, enabling the execution of autonomous reactive tasks.
