“…As an aid to the Bhattacarya tool, we also used the R package "VGAM" to construct an optimization framework to separate normal distributions and refine their estimates based on maximum likelihood methods and minimization of variances in the months containing bimodal or polymodal distributions (Kodama et al, 2005;Yee, 2021). Indeed, separating normal distributions with optimization algorithms is a commonly used method to identify cohorts for fast-growing and short-lived species (L opez-Martínez et al, 2020;Tresnati et al, 2020). This analysis confirmed the previously defined modal classes with the Bhattacharya tool.…”

Here, we present results from a study conducted in two major shrimp fishing grounds in the Northeastern Brazil Marine Ecoregion (NBME) that determined reproductive dynamics of the penaeid shrimps Xiphopenaeus kroyeri and Penaeus schmitti. We aimed to verify if the current closed season is appropriate and untangle the environmental drivers that control their dynamics. The periods of recruitment and reproduction of both species overlap significantly, with a major spawning peak taking place in the dry season and recruitment in the wet season. The recruitment process in both species seem to be indirectly controlled by the onset of the rainfall season, which triggers an increase in primary productivity. This indirect effect also appears to affect growth increments positively. Our results suggest that both species evolved to recruit in the wet and spawn at the dry season as mechanisms to maximize reproductive fitness. They also highlight the possible negative influence of climate change in tropical shrimp stocks and that the current local regulations must be adjusted to better protect them from overfishing. Therefore, we present multiple possibilities to the closed fishing season (CFS) addressed to local decision-makers and reinforce that environmental parameters and effects of environmental changes should be considered when planning management measures.

“…S. sp. 2 are strong jet-propulsion swimmers [35,51], selective feeders [31,67], and fast growers [78]. The high local variability in abundance of this species is most likely related to their need to move constantly in search for food.…”

Feeding Behavior, Shrinking, and the Role of Mucus in the Cannonball Jellyfish Stomolophus sp. 2 in Captivity

The importance of mucus produced by jellyfish species remains as understudied as their feeding behavior. Here, we study medusae under captivity, ascertain the role of mucus, and describe its feeding behavior. Between February and March 2019, live adult cannonball jellyfish, Stomolophus sp. 2, were collected in Las Guásimas Bay (Gulf of California, Mexico) and were offered fish eggs, mollusk “D” larvae, or Artemia nauplii in 4-day trials. Descriptions of feeding structures were provided for S. sp. 2. Digitata adhere food and scapulets fragment them, which, driven by water flow, pass via transport channels to the esophagus and the gastrovascular chamber where food is digested. Due to stress by handling, medusae produced mucus and water, lost feeding structures, and decreased in size. Based on our observations and a thorough literature review, we conclude that the production of mucus in S. sp. 2 plays several roles, facilitating capture and packing of prey, acting as a defense mechanism, and facilitating sexual reproduction; the latter improves the likelihood of a population persisting in the long run, because fertilized oocytes in mucus transform to planulae, settle, and transform into asexually reproducing polyps. Polyps live longer than the other life stages and are more resistant to adverse environmental conditions than the medusoid sexual stage.

“…Nishikawa et al [41] presented an update on fisheries in Thailand, and in Pakistan two species of scyphozoans, Catostylus perezi and Rhopilema hispidum, are commercially exploited [33] alongside a candidate species, Crambionella orsini [42]. In America, Lopez-Martinez [43] described the growth of Stomolophus meleagris in the Gulf of California, facilitating stock assessment and estimates on harvest frequency, which are a prerequisite to establish a sustainable fishery. Fahrenbruch [28] and Cruz-Colín et al [29] provided information on Latin American jellyfish fisheries, focusing on Nicaragua and Mexico, respectively, and discussed the magnitude and practices in light of economic and often neglected social aspects of jellyfish fisheries.…”

Jellyfishing in Europe: Current Status, Knowledge Gaps, and Future Directions towards a Sustainable Practice

Jellyfish are often described as a nuisance species, but as our understanding shifts to more ecosystem-based conceptions, they are also recognized as both important components of marine ecosystems and a resource for humans. Here, we describe global jellyfish fisheries and review production, fishing methods, and applications based on the existing literature. We then focus on future development of a European jellyfish fishery based on current and recent EU research initiatives. Jellyfish have been a staple food in East Asia for eons and now show a potential for non-food applications as well. The main fishing methods are mostly traditional, with set-nets, driftnets, hand-nets, and scoop-nets utilizing small crafts or beach-seines. All require a lot of manual labor, thus providing vital, albeit seasonal, occupation to weaker populations. Larger commercial vessels such as purse seines and trawlers are newly introduced métiers which may enable a larger catch per unit effort and total catch, but pose questions of selectivity, bycatch, vessel stability, and transshipment. Social concerns arising from the seasonality of jellyfish fisheries must be met in SE Asia, Latin America, and in any location where new fisheries are established. In the EU, we recognize at least 15 species showing potential for commercial harvesting, but as of 2021, a commercial fishery has yet to be developed; as in finfish fisheries, we advise caution and recognition of the role of jellyfish in marine ecosystems in doing so. Sustainable harvesting techniques and practices must be developed and implemented for a viable practice to emerge, and social and ecological needs must also be incorporated into the management plan. Once established, the catch, effort, and stock status must be monitored, regulated, and properly reported to FAO by countries seeking a viable jellyfish fishery. In the near future, novel applications for jellyfish will offer added value and new markets for this traditional resource.
