Protecting herbivorous fish, to secure a future for corals
Herbivorous fish rarely go unnoticed. Their brilliant colors illuminate the reef to the delight of scuba divers. But more importantly, these iconic fish are also vital for the conservation of coral reefs.
Herbivorous fish feed on the algae that grow on corals and compete with them for light and oxygen. By eating the algae, these tiny fish play a big role in the survival of the entire ecosystem.
Species of these herbivorous fish include: parrotfish, which eat corals that break off the reef and excrete them as white sand; damselfish, which fend off the macro algae growth that kills coral; and surgeonfish, whose most famous representative is Dory from Finding Nemo.
But corals are quickly losing their greatest allies. Populations of herbivorous fish are dwindling, particularly in the Caribbean.
The overfishing of commercial species is driving artisanal fishermen to capture even the youngest herbivorous fish, preventing those species from replenishing their numbers.
The loss of these fish is one more threat to coral reefs, already fragile ecosystems that are increasingly vulnerable to climate change. Preserving our reefs will ensure we continue to enjoy the services they provide. Among other things, coral reefs act as fish hatcheries, natural barriers against storms and hurricanes, and the source of medicines that treat illnesses like cancer and Alzheimer’s.

Fact Sheet: SPAW Protocol (Specially Protected Areas and Wildlife)
The Convention for the Protection and Development of the Marine Environment in the Wider Caribbean Region (Cartagena Convention) and its Protocol for Specially Protected Areas and Wildlife (SPAW Protocol) establishes that Contracting Parties have the obligation to regulate the protection of the vulnerable species and ecosystems of the region. The revised criteria for the nomination of species (1, 3, 4, 5, 6 and 10) determines the need to include essential species for vulnerable ecosystems - such as coral reefs, mangroves and seagrasses - in the species lists of Annexes II and III of the SPAW Protocol. The national or regional measures imply in a different way protection processes, biological monitoring of species, fishing recovery zones; analysis of catch data, health status of ecosystems, population dynamics and size; closed periods; and regulation of the capture, possession, transport, trade or total prohibition of the use of the species. In 2018, the Scientific and Technical Advisory Committee (STAC) prioritized the evaluation of herbivorous fish and currently the Species Working Group carries out the evaluation of parrotfish through the integration and analysis of scientific and regulatory data. Eleven of the 17 countries that have signed the Protocol have generated regulatory measures on herbivorous fish. Some regulatory experiences are in force, others are not, and there are those that came into force recently.

ON WORLD OCEAN DAY: An open letter
If we have learned anything from the Covid-19 pandemic it is that we are all inextricably connected with each other and the natural world. Without greater balance and cooperation we cannot survive as a species. Human wellbeing is at the heart of what we do. Our work, to protect the ocean is driven by the reality that humankind needs a healthy planet that can sustain life, for the sake of our homes, health, livelihoods and food. Many have taken the rupture to our lives caused by Covid-19 to think about this and about how we can rebuild better, learning from the pandemic to achieve a greater balance and to protect the fundamentals which make life on Earth possible. Doing so is a necessity. We do not have the luxury of choosing between paths which damage the natural world and those which do not. If we continue to harm nature at the rate we have been, our world will not be able to sustain human wellbeing – from jobs to food security and health. We have been given a stark warning. Once we emerge and start to rebuild, we need to do so in a way that protects the fundamentals that all human beings rely upon, foremost among these being a planet capable of sustaining human life. Governments will be put under pressure to drop environmental protections to make it easier for industry to operate; to privilege short term economics and job increases over other considerations. These will be presented as a choice – choose humans over nature - but it is not a real choice. For the good of humankind, we must achieve balance with the natural world, a coexistence which ultimately enables us to thrive. If we do not achieve that balance, take action to do better now, the rupture in our lives will get bigger, we will face other, escalating global disasters. We ask governments to protect human wellbeing and to make decisions which keep a functioning blue planet beneath our feet.

What I learned from my internship at AIDA
Last year, I completed a three-month internship with AIDA in La Paz, the capital of Baja California Sur, Mexico. It was part of the academic process to become a lawyer in Germany, my home country. The internship allowed me to combine my professional training with my passion for nature, as well as to gain experience working with an international NGO in the field of environmental law. I applied to the internship with AIDA's Marine Biodiversity and Coastal Protection Program without specifying a preferred location. Imagine my delight to learn that the internship would take place in La Paz, Mexico, a small city surrounded by nature. Coming from one of the most densely populated countries in the world, it was amazing to live in a place with so much space. I was fascinated by the diversity of ecosystems in the area: deserts, mangroves, mountainous pine forests, and the rock and coral reefs of the Gulf of California. On my first weekend, I was able to take in the abundance of wildlife in La Paz when Camilo Thompson, AIDA attorney and my supervisor, and Mario del Angel, his neighbor and a kayak guide, took me on a tour of the El Mogote wetlands, an ecosystem of international importance. I was impressed to see, in the first light of day, a group of dolphins in the bay. The morning was complete when I had my first chilaquiles, a typical Mexican dish, for breakfast. As we toured the waterways taking pictures of herons among the mangroves, I learned about the importance of coastal wetlands—they serve as habitat for key species and are natural carbon sinks. From the beginning of my internship, I participated in the virtual meetings of AIDA’s marine team, distributed throughout several countries of the region. I learned about the variety of animals and ecosystems that AIDA works to protect. From the office in La Paz, our contribution was focused on Mexico. I learned about national regulations related to reefs, herbivorous fish, and Natural Protected Areas. I supported research on the state of protection of these fish, which are essential for keeping Latin American and global coral reefs healthy. The combination of direct contact with nature and working in the office for local and regional projects gave me a different perspective on the nature of environmental law, and increased my motivation to learn. I learned that AIDA has worked for years with other organizations, local stakeholders, and scientists to protect fisheries and endangered species such as whales and sea turtles. One of the most enriching aspects of my internship was being able to experience first-hand the natural wealth that AIDA seeks to preserve. Though I’d been a diver for many years, I never ceased to be amazed by the sight of sea lions, bull and hammerhead sharks, killer whales, rays, sea turtles, and countless species of reef fish in their natural habitat. While in La Paz, I finished my rescue diver course and accompanied a team of marine biologists to conduct a visual census of marine life on Espiritu Santo Island. On four occasions, I visited Cabo Pulmo National Park, the largest coral reserve in the Gulf of California. I went diving and snorkeling. I participated in meetings of the Cabo Pulmo Vivo coalition, dedicated to protecting the park and its area of influence. It was gratifying to know that I was doing my small part for the site’s conservation. The internship gave my professional training a multidisciplinary approach. La Paz is one of the scientific centers of marine biology in Mexico and, while there, I was able to exchange ideas with marine biologists on diving trips and while socializing in bars in the city. Around La Paz, I was also able to spend time bird watching, one of my hobbies. The state of Baja California Sur is home to roughly 432 species of birds. I was able to see a wide variety of migratory species, as well five of the six endemic ones. I completed the internship very grateful for the experiences I had gained. Now, I’m back in Berlin, but I plan to return soon to La Paz to see the birds, whale sharks, and other majestic species that inhabit the area and are living proof of the valuable work of organizations like AIDA.
