Effects of diet stocking density and substrate on. The blue crab (Callinectes sapidus Rathbun) is a ubiquitous crustacean in San Antonio Bay, and on the Texas coast. It is ecologically important as both prey and predator, and is an important fishery resource for humans. The crab migrates between sea and estuary as part of its life cycle,, Ocean acidification substantially reduced the growth, condition, and survival of two phylogenetically diverse crab species in this long-term experiment. Even a modest decline of ∼0.2 pH units, a decline expected within the next century, had significant effects on both species..
