3 ways to save Nemo and Dory

With the release of Finding Dory on June 17, a global spike in marine aquarium fish demand is expected. The Philippines and Indonesia are the world’s top exporters of wild-caught marine fish, supplying 85% of the trade, so Pinoy fishers will soon be scouring reefs for Nemo, Dory, and all their finned friends. What can we do to protect them?  

1. Choose freshwater fish 

Goldfish, guppies, tetras and many freshwater fish are bred by the billions and are well-adapted to aquarium life. Farm-raised fish are cheaper, hardier and environmentally-sound options to marine fish. Since raising aquarium fish can be 250 times more profitable than raising tilapia, it can be a sunrise industry for the Philippines.

Freshwater fish are our best alternatives to marine fish because only 10% of them are still caught from the wild, like African Rift Lake cichlids or angelfish from the Amazon River. Innovations in breeding might soon end the need to catch them in rivers and lakes while still supplying aquarists with the living jewels they love.

2. Choose tough marine fish

Marine fish are hard to keep because 95% of them are taken from the most stable environment on Earth – the ocean. Most can’t adapt to life in the average home aquarium, where water parameters fluctuate daily. Many are still caught with cyanide, which stuns hard-to-catch fish but kills up to 75% of them. Popular fish like angelfish, butterflyfish, and Moorish idols are specialized feeders which feed on coral, sponges, and other tasty treats the average hobbyist probably won’t be able to provide. This is why so few fish survive beyond a year.

Still, a few marine fish species can be kept in aquaria. Hardy and brightly-colored damselfish, gobies, and blennies are good choices. Clownfish are the most popular, accounting for 40% of the trade. There are actually 30 clownfish species and Nemo is a Common Clownfish (Amphiprion ocellaris). Clownfish are relatively hardy and can be commercially-bred – but 75% of them still come from the wild.

Dory is another story. First, she’s not related to the Cream Dory we love to eat. Second, she’s very, very hard to keep. Dory’s a Regal Tang (Paracanthus hepatus) and feeds almost exclusively on algae and seaweed. She’s prone to parasites and gets sick easily.

Most importantly, the technology to breed her kind is still years off – so every single Dory you’ll see will have been plucked from the sea! If you really want to keep marine fish, then consult veteran hobbyists and forums like the Philippine Marine and Reef Aquarium Society (PMRAS), which encourages responsible fishkeeping. Get fish from reputable dealers like RVS Fishworld, which only sells cyanide-free fish caught by hand nets.

3. See them in the wild where they belong

Fortunately, the Philippines is part of the Coral Triangle and is among the richest countries in terms of marine life (this is why we export so much marine fish anyway). Diving or snorkelling here is way cheaper than in any other country. Wherever you are, there’ll be a reef nearby: Manila has the rich reefs of Anilao in Batangas, Cebu has Moalboal, Davao has Samal Island – even mountainous Baguio has La Union!

So what might happen if we don’t heed these 3 steps? Let’s look at another marine fish, the Banggai cardinalfish (Pterapogon kauderni), found only in Indonesia. According to conservation group Fondation Franz Weber and scientist Dr Alejandro Vagelli, from a global population of about 20 million in 1995, only about 1.4 million of them are left. Up to 500,000 are still caught annually to supply the aquarium trade.

This means that without immediate conservation measures, they’ll be functionally extinct in just a few years. The European Union has now submitted a proposal to control the trade in the species. A hobby should cultivate love – and fish enthusiasts would be the last to want to lose beauties like the Banggai cardinalfish.

To spread the word on the web, Best Alternatives is launching the #DefendDory campaign by calling on netizens to change their profile photos from now to July. Instead of wanting to possess fish, let Finding Dory inspire us all to see them in their home – the big blue, where Nemo, Dory, and all their friends belong. – Rappler.com
