Fish Cage Stocking

I’ve never put too much thought into aquaculture. Most of my interest in fish and fisheries has been centered around the natural environment and wild caught fisheries. However, now I am working in the Municipal Agriculture Office of a town with a massive aquaculture industry. Fish, crabs, prawns, oysters, and mussels are all raised and harvested here through a variety of methods. I have a lot to learn.

One popular method of fish aquaculture is by floating fish cages. Yesterday, I got to go out and observe the stocking (or introduction of young fish) to one of these floating structures. BFAR (Bureau of Fisheries and Aquatic Resources) provided almost 2,000 young snapper to be stocked into ponds in the coastal bay by the Bantay Dagat (literally “sea guard” in Filipino). Here are some pictures of the process:

BFAR employees dropped off two coolers filled with young fish. These fish were then transported by boat to the fish cage, maybe 100 meters from shore.

After pulling up to the cages, held in place by 8 long bamboo beams, the Bantay Dagat team got to work, adding additional nets and letting the bags of fish acclimate to their new environment (just like when you get a new goldfish!).

Once everything was secure and net were weighted down using liter bottles filled with sand and water, it was time to release the fish!

 

Before heading back, mesh covers were added over the cages and one Bantay Dagat member hopped in to do some last minute repairs.

Now, everyday, twice a day, these fish will need to be fed. As they grow, they will be spread out into different cages and separated by size. It will be 6 months before they are ready for harvest. Pretty neat.
