By applying temperature shocks at different times after fertilization, researchers found that a 3-minute cold shock at 6 \u00b0C, given 28 minutes after fertilization, produced the highest tetraploid percentage (78.33%) while maintaining viable survival rates.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tetraploid catfish are particularly valuable in aquaculture because they can be used to produce triploid offspring, which grow faster, are more disease-resistant, and have better meat quality. This breakthrough provides a promising method for improving catfish farming efficiency in Indonesia and beyond, contributing to sustainable aquaculture practices and food security.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This research aligns with the United Nations Sustainable Development Goals (SDG 2 \u2013 Zero Hunger, SDG 12 \u2013 Responsible Consumption and Production, SDG 14 \u2013 Life Below Water, and SDG 15 \u2013 Life on Land).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Full article:<a href=\"https:\/\/doi.org\/10.48048\/tis.2025.9204\"> Effect of Cold Shock on Larval Viability and Tetraploid Percentage of Asian Redtail Catfish, <em>Hemibagrus nemurus<\/em> (Valenciennes, 1840)<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Meet the Researchers<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This study was conducted by Dwi Puji Hartono (Universitas Padjadjaran &amp; Politeknik Negeri Lampung), Alimuddin Alimuddin (IPB University), Ibnu Dwi Buwono, and Yudi Nurul Ihsan (Universitas Padjadjaran).<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Hashtags<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">#AquacultureInnovation #CatfishResearch #ColdShock #FishGenetics #UnpadResearch #SDG2 #SDG12 #SDG14 #SDG15<\/p>","protected":false},"excerpt":{"rendered":"<p>A recent study published in Trends in Sciences (2025) investigated how cold shock treatments affect larval viability and chromosome manipulation in the Asian redtail catfish (Hemibagrus nemurus).
