Researchers focused on three key species landed at Brak Muncar Fish Landing Port between March 2023 and February 2024: the pelagic thresher (<em>Alopias pelagicus<\/em>), blacktip reef shark (<em>Carcharhinus melanopterus<\/em>), and coral catshark (<em>Atelomycterus marmoratus<\/em>).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A total of <strong>299 sharks<\/strong> were recorded, with <em>A. marmoratus<\/em> (140 individuals) and <em>C. melanopterus<\/em> (131 individuals) dominating the catches. Alarmingly, most individuals were <strong>juveniles<\/strong>\u2014a sign of potential overexploitation. Size data showed <em>C. melanopterus<\/em> (45\u201356.6 cm) and <em>A. pelagicus<\/em> (137.8\u2013172.7 cm) were frequently caught before reaching reproductive maturity, raising concerns about population sustainability. Sex ratio analysis revealed balanced proportions across species, although <em>A. marmoratus<\/em> showed a slight female bias.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sea surface temperature (SST), ranging between <strong>27.3\u201330.4\u00b0C<\/strong>, emerged as a significant factor influencing shark catches. Statistical analysis showed a <strong>strong correlation<\/strong> for <em>C. melanopterus<\/em> (R = 0.650), a <strong>moderate correlation<\/strong> for <em>A. pelagicus<\/em> (R = 0.496), and negligible influence for <em>A. marmoratus<\/em> (R = 0.085), reflecting the species\u2019 site fidelity to coral reef habitats. Seasonal shifts also played a role, with catches peaking during breeding and upwelling periods when prey availability increased.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The study emphasizes urgent management interventions, including stricter bycatch regulations, temporary no-catch zones in breeding areas, and better alignment with IUCN and CITES conservation listings. Training fishers in selective techniques and developing community-based monitoring systems are also recommended to safeguard shark populations. By linking ecological data with fisheries management, the research contributes valuable insights toward <strong>sustainable shark conservation in Indonesia\u2019s waters<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Credits:<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This study was conducted by <strong>Michelle Levina<\/strong>, <strong>Sunarto<\/strong>, <strong>Wahyuniar Pamungkas<\/strong>, <strong>Mochamad Rudyansyah Ismail<\/strong> (Universitas Padjadjaran), and <strong>Muhammad Ghozaly Salim<\/strong> (Mobula Project Indonesia).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Hashtags:<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">#SharkConservation #SDG14 #MarineResearch #BaliStrait #BycatchReduction #SustainableFisheries<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Publication Link:<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/ejabf.journals.ekb.eg\/article_418033.html\">https:\/\/ejabf.journals.ekb.eg\/article_418033.html<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Original Title: Length Distribution and Abundance of Sharks and Relationship with Temperature in the Bali Strait Waters SDGs Connection: Secondary SDGs: SDG 13 \u2013 Climate Action; SDG 12 \u2013 Responsible Consumption and Production Short Narrative Explanation: This study explores the size distribution, abundance, and environmental drivers of shark bycatch in the Bali Strait, Indonesia, a [&hellip;]<\/p>\n","protected":false},"author":1001026,"featured_media":18780,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4,52,68],"tags":[],"class_list":["post-18776","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-publikasidanartikel","category-riset-dan-inovasi","category-sdgs-papers"],"_links":{"self":[{"href":"https:\/\/fpik.unpad.ac.id\/en\/wp-json\/wp\/v2\/posts\/18776","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/fpik.unpad.ac.id\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/fpik.unpad.ac.id\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/fpik.unpad.ac.id\/en\/wp-json\/wp\/v2\/users\/1001026"}],"replies":[{"embeddable":true,"href":"https:\/\/fpik.unpad.ac.id\/en\/wp-json\/wp\/v2\/comments?post=18776"}],"version-history":[{"count":1,"href":"https:\/\/fpik.unpad.ac.id\/en\/wp-json\/wp\/v2\/posts\/18776\/revisions"}],"predecessor-version":[{"id":18781,"href":"https:\/\/fpik.unpad.ac.id\/en\/wp-json\/wp\/v2\/posts\/18776\/revisions\/18781"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/fpik.unpad.ac.id\/en\/wp-json\/wp\/v2\/media\/18780"}],"wp:attachment":[{"href":"https:\/\/fpik.unpad.ac.id\/en\/wp-json\/wp\/v2\/media?parent=18776"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/fpik.unpad.ac.id\/en\/wp-json\/wp\/v2\/categories?post=18776"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/fpik.unpad.ac.id\/en\/wp-json\/wp\/v2\/tags?post=18776"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
