ABSTRACT Draft identification guide for species of Mobulidae family, which is commonly observed as by-catch in tuna associated fishery in the region is presented. INTRODUCTION Species of Mobulidae family are a common bycatch occurs in the pelagic tuna fisheries of the Indian Ocean both in the industrial (purse seine and longline) and artisanal (gillnets) sector (Romanov 2002; White et al., 2006; Romanov et al., 2008). Apparently these species also subject of overexploitation: most of Indian Ocean species marked as vulnerable or near threatened at the global level, however local assessment are often not exist (Table).

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. -

BIOLOGY Devil and manta rays (family Mobulidae, the mobulid rays) are slow-growing, large-bodied animals with some species occurring in small, highly fragmented populations. Mobulid rays are pelagic, filter-feeders, with populations sparsely distributed across tropical and warm temperate oceans. Currently, nine species of devil ray (genus Mobula) and two species of manta ray (genus Manta) are recognized by CMS1. Mobulid rays have among the lowest fecundity of all elasmobranchs (1 young every 2-3 years), and a late age of maturity (up to 8 years), resulting in population growth rates among the lowest for elasmobranchs (Dulvy et al. 2014; Pardo et al 2016). 2. DISTRIBUTION The three largest-bodied species of Mobula (M. japanica, M. tarapacana, and M. thurstoni), and the oceanic manta (M. birostris) have circumglobal tropical and subtropical geographic ranges. The overlapping range distributions of mobulids, difficulty in differentiating between species, and lack of standardized reporting of fisheries data make it difficult to determine each species’ geographical extent. -
Assessing Sharks and Rays in Shallow Coastal Habitats Using Baited
Assessing sharks and rays in shallow coastal habitats using baited underwater video and aerial surveys in the Red Sea Thesis by Ashlie J. McIvor In Partial Fulfilment of the Requirements For the Degree of Master of Science King Abdullah University of Science and Technology Thuwal, Kingdom of Saudi Arabia May, 2020 2 EXAMINATION COMMITTEE PAGE The thesis of Ashlie Jane McIvor is approved by the examination committee. Committee Chairperson: Prof. Michael Berumen Committee Members: Prof. Burton Jones, Dr. Darren Coker, Dr. Julia Spaet [external] 3 © May, 2020 Ashlie J. McIvor All Rights Reserved 4 ABSTRACT Years of unregulated fishing activity have resulted in low abundances of elasmobranch species in the Saudi Arabian Red Sea. Coastal populations of sharks and rays in the region remain largely understudied and may be at risk from large-scale coastal development projects. Here we aim to address this pressing need for information by using fish market, unmanned aerial vehicle and baited remote underwater video surveys to quantify the abundance and diversity of sharks and rays in coastal habitats in the Saudi Arabian central Red Sea. Our analysis showed that the majority of observed individuals were batoids, specifically blue-spotted ribbontail stingrays (Taeniura lymma) and reticulate whiprays (Himantura sp.). Aerial surveys observed a catch per unit effort two orders of magnitude greater than underwater video surveys, yet did not detect any shark species. In contrast, baited camera surveys observed both lemon sharks (Negaprion acutidens) and tawny nurse sharks (Nebrius ferrugineus), but in very low quantities (one individual of each species). The combination of survey techniques revealed a higher diversity of elasmobranch presence than using either method alone, however many species of elasmobranch known to exist in the Red Sea were not detected. -
Devils in Distress: the Plight of Mobula Rays
CMS/Sharks/MOS2/Inf.14 Devils in Distress The Plight of Mobula Rays A school of Atlantic pygmy devil rays (Mobula hypostoma) off the Yucatán Peninsula in the Caribbean | Photo © Shawn Henrichs obula rays (Mobula spp.; Family: Mobulidae; commonly referred to as devil rays) are at great risk of severe global Mpopulation declines due to target and incidental fishing pressure1. Similar to the closely related and larger manta rays (Manta spp.)*, Mobula generally grow slowly, mature late, and produce few offspring over long lifetimes1,2. This life history strategy, coupled with their migratory nature and inherent schooling behaviour, makes these species extremely vulnerable to overexploitation. Escalating demand for dried Mobula gill plates for use in Chinese medicine, as well as meat and cartilage, has led to targeting of these vulnerable species through fisheries that are largely unregulated and unmonitored. Significant catch declines have been observed in a number of locations in the Indo-Pacific, Eastern Pacific, and Indian Ocean regions, often despite evidence of increased fishing effort. Population declines are likely occurring in other locations, but have gone unnoticed. Morphological similarities across the nine Mobula spp. and their traded gill plates, combined with overlapping geographic distributions, make species identification difficult. As a result, detailed reporting of catches from the vast majority of countries is lacking, presenting a challenge for population assessment. Measures to ensure sustainability of Mobula catch through fisheries management and international trade controls are also currently lacking. Change is needed now before overfishing leads to severe, perhaps irreparable depletion. Listing Mobula under Appendix II of the Convention on International Trade in Endangered Species (CITES) is warranted to improve fisheries and trade data, establish science-based exports limits, bolster enforcement of national protections, and complement listing under the Convention on Conservation of Migratory Species of Wild Animals (CMS). -
