“…To date, reports regarding shark diversity of Guatemala´s Caribbean Sea are scare (Thorson et al 1966;HacohenDomené et al 2016;Polanco-Vásquez et al 2017). This study forms the first confirmed records of H. perlo in Guatemala's Caribbean Sea and increase the number of known shark species in Guatemala.…”

Background: This report represents the first record of the sharpnose sevengill shark Heptranchias perlo in Guatemala's Caribbean Sea. Methods: Two H. perlo specimens were captured by artisanal fishermen of the coastal community, El Quetzalito. All specimens were captured with a trammel net, in waters of 200 m depth Results: Both specimens were female with total lengths of 280 and 370 mm. Details regarding the identification and measurement of both specimens are presented. Conclusion: These specimens represent the first record of both species in Guatemalan waters. Also, this report further increases the species' range of distribution in the Caribbean and Central America.

“…Additionally, landings monitoring in this area has resulted in at least eight new species records for several deep-sea chondrichthyes species in Guatemala´s Caribbean Sea such as: Hexanchus vitulus, Centrophorus spp., Cirrihigaleus spp., Squalus spp., etc. (this study; [20][21][22]). Although deep-sea sharks are not regularly targeted by fishers, they are occasionally caught.…”

Small-scale shark and ray fisheries are conducted throughout Central America's Caribbean coast. Yet, there is limited information regarding catch composition and diversity of these fisheries, especially in Guatemala. Surveys of catch landings were conducted in two of Guatemala's primary Caribbean coastal shark and ray fishing communities, El Quetzalito and Livingston, between January 2015 and July 2017. Biological data from 688 landed chondrichthyans were collected, with 31 species (24 sharks, six rays and one chimaera) identified. The four most frequently captured species included Carcharhinus falciformis (30.2%), Sphyrna lewini (12.7%), Hypanus guttatus (12%) and Rhizoprionodon spp. (6.7%). Landed sharks contained most size classes with a high proportion of juveniles of species with low productivity. The large-bodied species C. falciformis and S. lewini were often recorded at sizes below known maturity; 96.6% and 85.1%, of the captured individuals were immature, respectively. This study can serve as a baseline to determine future trends in the elasmobranch fisheries conducted by Guatemala's Caribbean coastal communities and support assessments on the persistence of the fisheries.

“…This effort expansion is revealed by new species and new records in recent years in regions including the Caribbean Sea and Andaman Sea (e.g. Kumar et al., 2018; Polanco‐Vásquez et al., 2017). In the Caribbean Sea, interest in developing deepwater fisheries has grown (e.g.…”

“…As mentioned previously, N. pinnata is currently targeted intensively off the coast of India for its liver oil, and much of its known distribution around Africa overlaps with intensive, and often illegal, fishing efforts from distant water fleets (Belhabib, 2017). In the Caribbean, N. carri is increasingly being observed in developing deepwater fisheries across the southern Caribbean Sea, where a number of fisheries using multiple gear types reach depths of 800 m, covering the entire known depth range of the species (Benavides et al., 2014; Polanco‐Vásquez et al., 2017; Oscar Lasso Alcalá, personal communication). Catch rates and utilization of the species are not well known.…”

Ghosts of the deep – Biodiversity, fisheries, and extinction risk of ghost sharks

et al. 2020

View full text Add to dashboard Cite

Ghost sharks (subclass Holocephali) remain a largely data‐poor group of cartilaginous fishes. The general paucity of attention may partially be related to identification and unresolved taxonomic issues, occurrence in the deep oceans, and their low value and interest in fisheries (which some notable exceptions). Here, we synthesize and assess the extinction risk of all known extant ghost sharks (52 species) by applying the IUCN Red List of Threatened Species Categories and Criteria. Ghost sharks have a low proportion of threatened (8%) and Near Threatened (8%) species, with most species (69%) assessed as Least Concern. The group still exhibits some data deficiency (15%), and biological information is lacking for most species. Endemism is high, with 37% of species known from only one location or one country. Species richness was highest in the Northeast Atlantic, off the northwest coast of Africa (Morocco to Mauritania), the East China Sea, New Zealand and off the northwest coast of South America (Ecuador and Peru). Ghost sharks are predominately taken as by‐catch, but some targeted fishing and/or retention for the liver oil trade occurs. Species‐specific reporting, monitoring and management are required to assess population trends, and further investigation is needed on trade and use, particularly for higher risk species including the sicklefin chimaeras (genus Neoharriotta) and the American Elephantfish (Callorhynchus callorhynchus, Callorhinidae).
