I recently spent time in the fishing village of El Cuyo Yucatan, Mexico fishermen from the northern shore of the Yucatan Penensula have concentrated there due to unusual populations of octopus. Harvest levels are 10 times normal take for similar amount of effort. Would anyone venture a cause of this population explosion. Past harvest of grouper, sharks and snapper have undoubtably impacted the prey predator relationships but this population increase is sudden and extreme. Any opinions?
