“…However, while the authors highlighted the potential applications of these devices for feed management strategies in cages, they did not provide guidance on the percentage of the population which should be tagged to get an accurate overview of group behaviour. In experimental shrimp ponds, the proportion of the population that should be tagged needs to be carefully assessed but the low cost of each tag compared with data-loggers, acoustic and radio transmitters allows for a considerable number of individuals to be monitored (Thorstad et al 2013;Meynecke et al 2015). PIT-tags also represent a serious hazard for consumers, which undoubtedly will limit their use to a research context in experimental farms where they could help visualize movement patterns inside the pond and towards feeders (Table 1).…”

The penaeid shrimp farming industry is a fast-growing sector which continues to suffer from significant feeding inefficiencies. Shrimp are slow to feed on pellets, with consumption dependent on a wide range of environmental and physiological parameters. Feed management on farms remains mainly based on feeding trays which can be difficult to observe and often result in overfeeding. While our understanding of shrimp feeding behaviour is beginning to improve under laboratory conditions, much less is known about shrimp behaviour in production ponds. Consequently, there is a growing interest within the industry to improve observations of shrimp feeding behaviour in situ, although this can be difficult due to high water turbidity and the benthic nature of shrimp. This review identifies key questions that remain unanswered in relation to shrimp feeding behaviour under commercial aquaculture conditions, and considers how they could be addressed using state-of-the-art applications based on three technologies commonly used in other areas of aquaculture. The use of passive acoustics, computer vision and telemetry are highlighted, alongside their potential to help farmers achieve better feeding efficiencies and sustainability as well as to help understand shrimp feeding behaviour in relation to various biotic and abiotic parameters.

“…Beginning in March 2018, all crabs that were released back into the fishpond during crabbing sessions were tagged with T-bar anchor tags coded with unique identifiers (Hallprint, Australia). Although crabs are ecdysiasts and need to moult in order to grow, T-bar anchor tags are designed to be inserted between the carapace and first thoracic segment in order to be retained through moulting (McPherson 2002;Meynecke et al 2015). To ensure that the maximum number of tagged crabs would be captured, a larger-scale dedicated effort to tag crabs occurred in March and April 2019.…”

Hawaiian fishponds, or loko i‘a, are ancient aquaculture systems and models of sustainable aquatic resource management from traditional Native Hawaiian harvest practices. Of the 488 fishponds documented in ancient Hawai‘i, only 38 are currently actively managed. Building on Indigenous and local knowledge, fishponds are being adapted to current community needs. Functional fishponds perpetuate culture, improve food security, enhance ecosystem services and transform conservation biology through Indigenous perspectives. Here we examine how Indigenous practices effectively maintain sustainable harvest of an introduced, but economically important, crab species, the mud crab, Scylla serrata (Forskål 1775). The State of Hawai‘i has only a size limit, and no bag limits, for this species. With Indigenous management in a Hawaiian fishpond, limits are set and enforced in response to fluctuations in catch. We used a mark–recapture experiment to parameterise a size-structured population model, which we used to investigate the impact of changing harvest rates. Throughout the study period of 2017–20, the mean number of crabs per harvest was 28 individuals (s.d. = 7) and average catch per unit effort was 0.20 crabs per trap-hour (s.d. = 0.054). During winter, catch per unit effort was lower but mean crab size was larger than during summer. Model simulations indicated that current Indigenous practices are less likely to cause a decline in population growth rate than a strict size limit. Using information from Indigenous harvest practices and the mark–recapture study, we codeveloped a versatile crab population model that can be tailored to changing management objectives.

“…In contrast, internal tagging methods show high retention rates with minimal drawbacks (Sato et al, 2013), and do not show detrimental effects in the individual (Foote et al, 2018;Fuller and McEntire, 2013;Haddaway et al, 2011;Moraes-Costa and Schwamborn, 2018). Furthermore, internal tagging methods in crustaceans include microwire tags, (Sharp et al, 2000), visible elastomer implants and alphanumeric internal tags (Dinh et al, 2012;Haddaway et al, 2011), as well as passive integrated transponder (PIT) tags (Drew et al, 2012;Forsee and Albrecht, 2012;Haddaway et al, 2011;Meynecke et al, 2015;Moraes-Costa and Schwamborn, 2018;Sato et al, 2013).…”

La trazabilidad en acuicultura y estudios de campo requiere identificación confiable de los individuos. Las etiquetas internas pueden ayudar a mantener registros de identidad y evitar la pérdida típica de etiquetas externas debido a la muda en los crustáceos. Aquí presentamos el primer intento de implantar etiquetas de transpondedor integrado pasivo (PIT) en el cangrejo azul (Cardisoma crassum), en cautiverio, para evaluar su efecto en el estado de salud y su influencia en el peso y la mortalidad. Adicionalmente, la temperatura durante el experimento en cautiverio fue registrada para evaluar su efecto en la condición de los cangrejos. Las etiquetas PIT se implantaron por inyección en la base del cuarto pereiópodo. El cangrejo marcado más pequeño fue de 55,26 mm de ancho de cefalotórax; todos los cangrejos retuvieron los implantes hasta el término. La supervivencia fue del 77,8 % y no hubo diferencias en el peso y en el factor de condición como resultado de la implantación de la etiqueta. El deterioro de la condición del cangrejo se correlacionó con el estrés térmico. Un mayor desarrollo de la acuicultura debe controlar el estrés térmico en cautiverio para reducir la mortalidad. Las etiquetas PIT sirvieron como un medio confiable para la identificación individual de cangrejos azules.
