I was invited along to film a freediver hunt for yellow tail and dorado (mahi mahi) under the floating kelp paddys that float adrift off of the Southern California coast. These drifting kelp paddys are the 'only hotel in town' and thus become an ecosystem upon themselves. Juvenile reef fish such a half moon perch and tree fish can be found under them. Large pelagic fish congregate around them. We did find dorado, if you look closely you can see them spawn. The visibility was well over 100'. Underwater the dorado appear to be about 2' long, not over 3' as the are. The're just farther away then it seems.
