He is the former president of the Marcona Artisanal Fishing Community (<a href=\"https:\/\/www.instagram.com\/copmar_marcona\/\">COPMAR<\/a>), an association formed of numerous OSPAs that collect beached seaweed along southern Peru&#8217;s Marcona coastline.<\/p>\n\n\n\n<p>Faced with declining fish stocks and conflicts over what was left, fishers in Marcona organised themselves under COPMAR to better utilise resources. Their fishing zone (80 kilometres of coastline) was divided into sectors and distributed equally among fishers&#8217; associations.<\/p>\n\n\n\n<p>Milla says economics plays a greater role than environmental protection in this largely poor area: \u201cOur main concern, more than environmental, is social.\u201d<\/p>\n\n\n\n<p>The associations take it in turns to gather washed-up seaweed for one month, giving everyone a chance to make money. When not gathering seaweed, members of the associations supplement their income with fishing, or by taking jobs in the district capital, San Juan de Marcona, or the <a href=\"https:\/\/dialogue.earth\/es\/negocios\/marcona-megapuerto-desconcierta-pueblo-pescadores-peru\/\">local iron mining industry<\/a>.<\/p>\n\n\n\n<p>After being gathered from the coast, the seaweed is transported to desert plains where it is spread out to dry. That takes approximately two weeks in winter or five days during summer. It is then rolled and wrapped into balls that are sold to processing plants. Most is then exported to China.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div class=\"wp-block-cd-story-image aligncenter block--story-image block--story-image--article\" itemscope itemtype=\"http:\/\/schema.org\/ImageObject\"><div class=\"block--story-image__column\"><div class=\"block--story-image__image\"><img class=\"lazy\" data-src=\"https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20240705_Manuel-Milla_Marcona_Peru_Yuri-Hooker_Dialogue-Earth.jpg\" data-srcset=\"https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20240705_Manuel-Milla_Marcona_Peru_Yuri-Hooker_Dialogue-Earth-768x512.jpg 768w, https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20240705_Manuel-Milla_Marcona_Peru_Yuri-Hooker_Dialogue-Earth-1024x683.jpg 1024w, https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20240705_Manuel-Milla_Marcona_Peru_Yuri-Hooker_Dialogue-Earth-1400x934.jpg 1400w, https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20240705_Manuel-Milla_Marcona_Peru_Yuri-Hooker_Dialogue-Earth-1800x1200.jpg 2000w, https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20240705_Manuel-Milla_Marcona_Peru_Yuri-Hooker_Dialogue-Earth.jpg\" data-sizes=\"(max-width: 600px) 768px, (max-width: 999px) 1024px, (max-width: 1400px) 1400px, (max-width: 2000px) 2000px, 2560px\" alt=\"a man posing in front of the ocean\"\/><\/div><div class=\"block--story-image__content\"><div itemprop=\"caption\" class=\"block--story-image__caption\">Manuel Milla, former president of the Marcona Artisanal Fishing Community.

But Milla believes there is now so much of it in the San Fernando National Reserve (just north of San Juan de Marcona)&nbsp;that it should be harvested. This would help struggling local fishers, and he believes it would also benefit shellfish and help balance the local ecosystem.<\/p>\n\n\n\n<p>Other seaweed harvesters agree that the ecosystem could support the removal of algae, perhaps even through direct harvesting from the sea. But determining the status of seaweed populations is difficult.<\/p>\n\n\n\n<p>Jos\u00e9 Zavala is a specialist in macroalgae ecology and the former director general of research into demersal (seabed) and coastal resources at Peru\u2019s Institute of the Sea (IMARPE). Harvesting in Peru is carried out according to the results of IMARPE\u2019s evaluations and technical recommendations.<\/p>\n\n\n\n<p>Zavala says that although only the collection of beached seaweed is allowed currently, there is pressure from seaweed farmers to authorise some regulated direct extraction. This has happened on a handful of occasions in the past and always with prior study by IMARPE, which establishes the maximum permitted volume of extraction and other technical considerations. But \u201cit is very difficult to monitor compliance and the final damage to the ecosystem,\u201d notes Zavala.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div class=\"wp-block-cd-story-image aligncenter block--story-image block--story-image--article\" itemscope itemtype=\"http:\/\/schema.org\/ImageObject\"><div class=\"block--story-image__column\"><div class=\"block--story-image__image\"><img class=\"lazy\" data-src=\"https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20240705_kelp_collectors_Marcona_Peru_Yuri-Hooker-Dialogue-Earth.jpg\" data-srcset=\"https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20240705_kelp_collectors_Marcona_Peru_Yuri-Hooker-Dialogue-Earth-768x512.jpg 768w, https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20240705_kelp_collectors_Marcona_Peru_Yuri-Hooker-Dialogue-Earth-1024x683.jpg 1024w, https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20240705_kelp_collectors_Marcona_Peru_Yuri-Hooker-Dialogue-Earth-1400x934.jpg 1400w, https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20240705_kelp_collectors_Marcona_Peru_Yuri-Hooker-Dialogue-Earth-1800x1200.jpg 2000w, https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20240705_kelp_collectors_Marcona_Peru_Yuri-Hooker-Dialogue-Earth.jpg\" data-sizes=\"(max-width: 600px) 768px, (max-width: 999px) 1024px, (max-width: 1400px) 1400px, (max-width: 2000px) 2000px, 2560px\" alt=\"two people carrying seaweed on their shoulders, walking on the beach\"\/><\/div><div class=\"block--story-image__content\"><div itemprop=\"caption\" class=\"block--story-image__caption\">Local seaweed farmers want permission to remove some seaweed from protected areas such as the San Fernando National Reserve, near Marcona (Image: Yuri Hooker \/ Dialogue Earth)<\/div><\/div><\/div><meta itemprop=\"contentUrl\" content=\"https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20240705_kelp_collectors_Marcona_Peru_Yuri-Hooker-Dialogue-Earth.jpg\"\/><meta itemprop=\"contentSize\" content=\"2 MB\"\/><meta itemprop=\"height\" content=\"1707\"\/><meta itemprop=\"width\" content=\"2560\"\/><meta itemprop=\"author\"\/><meta itemprop=\"representativeOfPage\" content=\"true\"\/><\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div class=\"wp-block-cd-story-image aligncenter block--story-image block--story-image--article\" itemscope itemtype=\"http:\/\/schema.org\/ImageObject\"><div class=\"block--story-image__column\"><div class=\"block--story-image__image\"><img class=\"lazy\" data-src=\"https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20230721_kelp_rhizoids_shellfish_Peru_archive_Yuri-Hooker.jpg\" data-srcset=\"https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20230721_kelp_rhizoids_shellfish_Peru_archive_Yuri-Hooker-768x512.jpg 768w, https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20230721_kelp_rhizoids_shellfish_Peru_archive_Yuri-Hooker-1024x683.jpg 1024w, https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20230721_kelp_rhizoids_shellfish_Peru_archive_Yuri-Hooker-1400x934.jpg 1400w, https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20230721_kelp_rhizoids_shellfish_Peru_archive_Yuri-Hooker-1800x1200.jpg 2000w, https:\/\/dialogue.earth\/content\/uploads\/2024\/10\/20230721_kelp_rhizoids_shellfish_Peru_archive_Yuri-Hooker.jpg\" data-sizes=\"(max-width: 600px) 768px, (max-width: 999px) 1024px, (max-width: 1400px) 1400px, (max-width: 2000px) 2000px, 2560px\" alt=\"shellfish and kelp in the ocean \"\/><\/div><div class=\"block--story-image__content\"><div itemprop=\"caption\" class=\"block--story-image__caption\">Many invertebrate species, including economically important juvenile shellfish, live among the roots that attach kelp to rocks.
