class=\"wp-caption-text\">Tom\u00e1s Bravo &amp; Jos\u00e9 Pablo Puga<\/figcaption><\/figure><p data-start=\"214\" data-end=\"562\" class=\"translation-block\">Jos\u00e9 Pablo Puga, co-founder and CEO of ChucaoTech, pioneered the use of nanobubbles to tackle seabed pollution beneath salmon farms, but has since expanded into other applications and species. A mechanical engineer by training, Puga's early career began high in the Chilean desert. \u201cI worked for three years in the ALMA Observatory, the large radio telescope in the north of Chile,\u201d he recalls. But product design was his main ambition, and a scholarship to the University of Cambridge led to a dream job with Cambridge Consultants, designing consumer products in the UK. \u201cIt was my real school,\u201d he says. \u201cBut after a few years, I returned to Chile \u2013 drawn by nature \u2013 and moved south.\u201d<\/p><p data-start=\"1005\" data-end=\"1215\" class=\"translation-block\">That move put Puga at the heart of Chile\u2019s salmon farming industry. He joined Sealand Aquaculture as chief engineer at one of the country\u2019s largest recirculating aquaculture system (RAS) smolt facilities. \u201cThat was my first approach to aquaculture. I learned the ins and outs of water treatment, fish health and rearing,\u201d he recalls. It also sowed the seeds for ChucaoTech<\/p><p><div style=\"width: 800px;\" class=\"wp-video\"><video class=\"wp-video-shortcode\" id=\"video-1905-1\" width=\"800\" height=\"450\" loop preload=\"metadata\" controls=\"controls\"><source type=\"video\/mp4\" src=\"https:\/\/chucaotech.com\/wp-content\/uploads\/2025\/08\/entrevista_the-fish-site.mp4?_=1\" \/><a href=\"https:\/\/chucaotech.com\/wp-content\/uploads\/2025\/08\/entrevista_the-fish-site.mp4\">https:\/\/chucaotech.com\/wp-content\/uploads\/2025\/08\/entrevista_the-fish-site.mp4<\/a><\/video><\/div><\/p><p data-start=\"1400\" data-end=\"1620\" class=\"translation-block\">In 2017, Puga met Tomas Bravo, who\u2019d recently gained an MBA from Imperial College. Together, they launched Chucao Technology Consultants, originally intended as a broad engineering consultancy for salmon farmers. \u201cIt didn\u2019t work out as we\u2019d hoped,\u201d Puga admits, \u201cbut one challenge really stood out \u2013 seabed pollution.<\/p><p data-start=\"1752\" data-end=\"2151\" class=\"translation-block\">Open-net salmon farming creates a plume of organic waste from uneaten feed and fish faeces, most of which settles directly beneath the pens, disrupting marine ecosystems. Traditionally, farms simply let sites fallow after harvest, waiting for nature to work its magic. But recovery can take years, delaying the ability to restart production. \u201cThat\u2019s when we came across nanobubbles,\u201d says Puga.<\/p><p data-start=\"2227\" data-end=\"2413\" class=\"translation-block\">Although barely known in Chilean aquaculture at the time, nanobubbles \u2013 tiny gas bubbles less than 200 nanometres in diameter \u2013 appeared to offer a promising solution.<\/p><p data-start=\"2415\" data-end=\"2531\" class=\"translation-block\">\u201cBack then, if you talked about nanobubbles to a salmon farmer, they\u2019d ask, \u2018What the hell is that?\u2019\u201d he recalls. Scepticism was rife and there were even rumours that these tiny bubbles could harm the salmon. \u201cThere was misinformation about nanobubbles damaging fish gills. It took time to dismiss those fears,\u201d Puga explains.<\/p><p data-start=\"2756\" data-end=\"2959\" class=\"translation-block\">Undeterred, he and his team persisted and \u2013 according to Puga \u2013 in 2020 became the first company in the world to commercially apply nanobubbles for seabed remediation. \u201cWe realised injecting oxygen with nanobubbles could accelerate recovery of the seabed. And no one had done that before,\u201d he explains.<\/p><p data-start=\"3106\" data-end=\"3255\" class=\"translation-block\">They began by using third-party nanobubble generators, but quickly realised their limitations \u2013 especially in distant offshore locations. \u201cFarms here are remote. You might need to sail 20 hours just to get there. Equipment has to be simple, rugged and easy to fix,\u201d Puga points out.<\/p><p data-start=\"3406\" data-end=\"3496\" class=\"translation-block\">As a result, ChucaoTech built its own, complete with its own set of specifications. \u201cWe didn\u2019t aim to make the most nanobubbles \u2013 we focused on making enough, reliably, with low energy use and no moving parts,\u201d explains Puga. \u201cThat shift in thinking was key.\u201d<\/p><p data-start=\"3703\" data-end=\"3916\" class=\"translation-block\">Today, ChucaoTech\u2019s technology is used throughout the aquaculture production cycle \u2013 from hatchery tanks to seawater cages \u2013 with applications ranging from oxygenation to disinfection.<\/p><p data-start=\"3918\" data-end=\"3968\">And, according to Puga, the results have been impressive.<\/p><p data-start=\"3970\" data-end=\"4278\" class=\"translation-block\">\u201cIn salmon farming alone, we\u2019ve seen oxygen cost reductions of up to 45 percent, and growth rate increases of 10\u201320 percent in freshwater systems. One farm cycle here can spend half a million dollars on oxygen. If we can save them a quarter-million, that\u2019s huge,\u201d he points out.<\/p><p data-start=\"4280\" data-end=\"4504\">The company now has around 300 systems deployed in the aquaculture sector, following good feedback from early adopters, including Mowi Chile and Cermaq, who supported ChucaoTech\u2019s first pilots and full-farm deployments.<\/p><p data-start=\"4506\" data-end=\"4747\">What began as a niche remediation service is now a versatile platform for sustainable water treatment, expanding into shrimp and tilapia farming, as well as into agriculture and mining.<\/p><p data-start=\"4749\" data-end=\"5071\" class=\"translation-block\">\u201cIn agriculture, oxygenating irrigation water improves root health and boosts yields \u2013 especially in degraded soils,\u201d Puga explains. \u201cIn mining, we\u2019re injecting oxygen into copper leaching operations. Lab trials show metal recovery gains of 7\u201325 percent.\u201d<\/p><p data-start=\"5073\" data-end=\"5351\" class=\"translation-block\">The company has now opened offices in California (with a focus on agriculture) and in Europe, following interest from salmon farmers in Scotland, the Faroe Islands, Iceland and Norway \u2013 and the Puga has especially high hopes to drum up interest in Norway at the forthcoming Aqua Nor exhibition in Trondheim.<\/p><p data-start=\"5353\" data-end=\"5516\" class=\"translation-block\">\u201cNorway is like our sister country in salmon farming,\u201d says Puga. \u201cWe use their technology here. But now we\u2019re hoping to share what we\u2019ve learned back to them.\u201d<\/p><p data-start=\"5518\" data-end=\"5696\" class=\"translation-block\">While ChucaoTech have been joined by a number of competitors in the aquaculture space, Puga asserts that the \u201csimplicity and transparency\u201d of their nanobubble generators are what sets them apart.<\/p><p data-start=\"5698\" data-end=\"5840\" class=\"translation-block\">\u201cWe\u2019re not trying to dazzle people with complexity. Our systems are robust, efficient, and we work openly with integrators,\u201d he observes.<\/p><p data-start=\"5842\" data-end=\"5994\" class=\"translation-block\">Looking ahead, Puga believes that nanobubble technology is likely to become increasingly mainstream \u2013 not just in salmon, but also in warmwater species.<\/p><p data-start=\"5996\" data-end=\"6416\" class=\"translation-block\">\u201cI want nanobubble technology to become a category in aquaculture. Not for everything, but for key applications like oxygenation and seabed remediation, it should be standard,\u201d he argues. \u201cAnd I\u2019d love to see us bring this to places where it\u2019s harder to get investment \u2013 like shrimp, tilapia, and carp farming. These systems can be more sustainable. We just have to get there.\u201d<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-decba59 e-con-full e-flex e-con e-child\" data-id=\"decba59\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;_ha_eqh_enable&quot;:false}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-c10d933 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"c10d933\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-214ec09 e-con-full e-flex e-con e-child\" data-id=\"214ec09\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;_ha_eqh_enable&quot;:false}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-2eaf4c8 elementor-widget elementor-widget-text-editor\" data-id=\"2eaf4c8\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p class=\"translation-block\">Original source of the article:<a href=\"https:\/\/thefishsite.com\/articles\/how-mini-bubbles-can-have-a-massive-impact-on-aquaculture?x-craft-preview=4a14cf04d44f319d29823f120f07adc245511f6f1a8c5a368217a7d74c01e696fyqljzxooy&amp;token=gDYNMfCMkgEPVCS_3BcZ6if2BZRuloZd&amp;utm_source=linkedin&amp;utm_medium=post&amp;utm_campaign=feature18Aug25\" target=\"_self\"><strong><span style=\"color: #ff5416\"> thefishsite.com<\/span><\/strong><\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-152e302 e-flex e-con-boxed e-con e-parent\" data-id=\"152e302\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;_ha_eqh_enable&quot;:false}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>ChucaoTech, startup chilena fundada por Jos\u00e9 Pablo Puga, fue pionera en el uso de nanoburbujas&#8230;.<\/p>","protected":false},"author":5,"featured_media":1906,"comment_status":"closed","ping_status":"open","sticky":false,"template":"elementor_header_footer","format":"standard","meta":{"footnotes":""},"categories":[7,6],"tags":[8],"class_list":["post-1905","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-acuicultura","category-nanoburbujas","tag-noticia"],"_links":{"self":[{"href":"https:\/\/chucaotech.com\/en\/wp-json\/wp\/v2\/posts\/1905","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/chucaotech.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/chucaotech.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/chucaotech.com\/en\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/chucaotech.com\/en\/wp-json\/wp\/v2\/comments?post=1905"}],"version-history":[{"count":11,"href":"https:\/\/chucaotech.com\/en\/wp-json\/wp\/v2\/posts\/1905\/revisions"}],"predecessor-version":[{"id":2055,"href":"https:\/\/chucaotech.com\/en\/wp-json\/wp\/v2\/posts\/1905\/revisions\/2055"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/chucaotech.com\/en\/wp-json\/wp\/v2\/media\/1906"}],"wp:attachment":[{"href":"https:\/\/chucaotech.com\/en\/wp-json\/wp\/v2\/media?parent=1905"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/chucaotech.com\/en\/wp-json\/wp\/v2\/categories?post=1905"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/chucaotech.com\/en\/wp-json\/wp\/v2\/tags?post=1905"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
