Blue Growth: Sea Urchin Sustainable Aquaculture, Innovative Approaches

Guiding Sustainable Marine Aquaculture

shores. Aquaculture—the farming of fish, shellfish, or aquatic plants—has grown rapidly over the past several decades, and that growth is accelerating. Today, some 4,000 aquaculture enterprises in the United States, most of them small to mid-size, supply Americans with Atlantic salmon, hard clams, oysters, shrimp, and nearly all the catfish and trout we eat. As the industry matures, it holds bo...

Blue Crab Aquaculture in Ponds

North Carolina’s Blue Crab Fishery As North Carolina’s number one fishery, blue crabs, Callinectes sapidus, are part of an important industry for numerous coastal communities. The fishery supports commercial fishermen, dealers, gear providers and processors throughout the year. Fluctuations in landings have led to concerns over crab populations and the livelihood of the commercial crabbers they...

Sea urchin feeding fronts

Sea urchin feeding fronts are a striking example of spatial pattern formation in an ecological system. If it is assumed that urchins are asocial, and that they move randomly, then the formation of these dense fronts is an apparent paradox. The key lies in observations that urchins move further in areas where their algal food is less plentiful. This naturally leads to the accumulation of urchins...

Two New Approaches for Examining Multivariate Aquaculture Growth

Two new approaches foi the multivariate analysis of fish growth in aquaculture are presented. The first of these two approaches, the "extended Bayley plot" is a multiple regression expansion of an existing bivariate method, which permits the inclusion of environmental and treatment variables when estimating the parameters Lm and K of the von Bertalanflj. growth function, given precise measureme...
