ABSTRACT Digital aquaculture leverages advanced technologies and data‐driven methods, providing substantial benefits over traditional practices. This article presents a comprehensive review of three interconnected digital tasks, namely, fish tracking, counting, behaviour analysis, using novel unified approach. Unlike previous reviews which focused on single modalities or individual we analyse vision‐based (i.e., image‐ video‐based), acoustic‐based, biosensor‐based methods across all tasks. We examine their advantages, limitations, applications, highlighting recent advancements identifying critical cross‐cutting research gaps. The also includes emerging ideas such as applying multitask learning large language models to address various aspects monitoring, an approach not previously explored in literature. identify the major obstacles hindering progress this field, including scarcity datasets lack evaluation standards. To overcome current explore potential multimodal data fusion deep improve accuracy, robustness, efficiency integrated monitoring systems. In addition, provide summary existing available for analysis. holistic perspective offers roadmap future research, emphasizing need standards facilitate meaningful comparisons between promote practical implementations real‐world settings.

Abstract Cannibalism, the act of preying on and consuming a conspecific, is taxonomically widespread, putatively important in wild, particularly teleost fishes. Nonetheless, most studies cannibalism fishes have been performed laboratory. Here, we test four predictions for evolution by conducting one largest assessments wild to date coupled with mesocosm experiment. Focusing mosquitofishes guppies, examined 17 species (11,946 individuals) across 189 populations spanning both native invasive ranges including disparate types habitats. We found be quite rare wild: showed no evidence cannibalism, prevalence was typically less than 5% within when it occurred. Most victims were juveniles (94%; only half these appeared newborn offspring), remaining 6% being adult males. Females exhibited more males, but this partially explained their larger body size, suggesting greater energetic requirements reproduction likely play role as well. that dispersal‐limited environments had lower higher conspecific densities, intense resource competition drives cannibalistic behavior. Supporting conclusion, our experiment revealed increased density levels not associated juvenile or strongly influenced predation risk. suggest livebearing because conspecifics energetically costly becomes worth effort other food intense. Due artificially reduced cost capturing confined spaces, captive settings can much frequent.

Pikeperch aquaculture technologies have significantly improved, yet knowledge regarding the adaptation of pikeperch to captivity is very scarce. This study aimed evaluate survival, growth, stress response, and immune system function F2 generation subjected pond nursing – Recirculating Aquaculture System (RAS) dry feed adaptation, with either RAS or grow-out. in this research originated from broodstock reared during grow-out, while F1 wild breeders. Critical points fish growth were analyzed, including transport pond-nursed juveniles at 42 DPH, habituation (42–52 DPH) post-habituation (52–64 phase, as well on-grow/grow-out (64–154 phase. Our results showed better survival comparison However, was superior conventional Nevertheless, habituation, inferior, both terms fish.

Abstract The Eurasian otter, Lutra lutra , faced adversity in Europe the 1950s and 1960s due to hunting, declining fish populations American mink invasion. Slow recovery since 1970s led a ‘Near Threatened’ IUCN Red List status, but recent pollution, fishing pressure habitat loss caused slight population declines. Otters, known for aquatic habits, are mainly piscivorous exhibit solitaire or social behaviours. Infanticide with parent‐offspring cannibalism has been previously reported otter species, although suggested, it not documented before. This study presents first case of among free‐living otters observed northern Norway. Some authors described as an opportunistic resource‐efficient behaviour several mammal offering benefits like weight gain reduced competition, challenging view adverse health effects. Factors leading include ecological changes, resource competition other species global warming overfishing practices contributing increased competition. Further studies will be vital answering intriguing questions about implications conservation.
