Because otter trawls occasionally capture and kill loggerhead turtles, the Monterey Bay Aquarium Seafood Watch considers fish caught in this manner as a species to avoid.&nbsp; Handline and pot fisheries are more selective, and black sea bass caught this way are considered a &#8220;Best Choice&#8221; for consumers. &nbsp; Total commercial landings of black sea bass in the northern fishery peaked at 9,883 metric tons in 1952, but in recent years have been about 1,400 to 1,700 mt annually, worth a record $8.5 million in 2013.<\/p>\n<p>Because of their high commercial value, black sea bass are seen as a potentially valuable mariculture fish.&nbsp; Researchers in New England and elsewhere have been working with this species for several decades, but commercialization for aquaculture remains elusive.&nbsp; The ideal water temperature for black sea bass is 15 to 18 degrees C, so the northern stock migrates offshore and south in the winter.&nbsp; This means that in Maine they would need to be farmed in heated systems during winter. &nbsp; Black sea bass are protogynous hermaphrodites; a proportion of the fish population changes sex from female to male as they grow larger.&nbsp; This could prove to&nbsp; be a challenge for maintaining brood stock populations in captivity.&nbsp; Another challenge with this species is that they tend to be solitary and prefer inhabiting on-bottom structures.&nbsp; Despite these challenges, black sea bass remain of great interest as an aquaculture species because of their market demand, good price, and relatively fast growth rate. &nbsp;Former industry partner, Acadia Harvest, Inc., carried out growth, feeding, and marketing trials with black sea bass at the CCAR facility from 2014-2017.<\/p>\n<p>&nbsp;<\/p>\n<figure id=\"850\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-850\" src=\"https:\/\/umaine.edu\/cooperative-aquaculture\/wp-content\/uploads\/sites\/75\/2016\/03\/Chris-with-BSB.jpg\" alt=\"Chris with BSB\" width=\"500\" height=\"496\" srcset=\"https:\/\/umaine.edu\/cooperative-aquaculture\/wp-content\/uploads\/sites\/75\/2016\/03\/Chris-with-BSB.jpg 500w, https:\/\/umaine.edu\/cooperative-aquaculture\/wp-content\/uploads\/sites\/75\/2016\/03\/Chris-with-BSB-150x150.jpg 150w, https:\/\/umaine.edu\/cooperative-aquaculture\/wp-content\/uploads\/sites\/75\/2016\/03\/Chris-with-BSB-300x298.jpg 300w, https:\/\/umaine.edu\/cooperative-aquaculture\/wp-content\/uploads\/sites\/75\/2016\/03\/Chris-with-BSB-105x104.jpg 105w, https:\/\/umaine.edu\/cooperative-aquaculture\/wp-content\/uploads\/sites\/75\/2016\/03\/Chris-with-BSB-210x208.jpg 210w, https:\/\/umaine.edu\/cooperative-aquaculture\/wp-content\/uploads\/sites\/75\/2016\/03\/Chris-with-BSB-317x314.jpg 317w, https:\/\/umaine.edu\/cooperative-aquaculture\/wp-content\/uploads\/sites\/75\/2016\/03\/Chris-with-BSB-423x420.jpg 423w\" sizes=\"auto, (max-width: 320px) 85vw, (max-width: 768px) 67vw, (max-width: 1024px) 62vw,500px\" \/><figcaption class=\"wp-caption-text\"><em>Acadia Harvest Inc President Chris Heinig with one of their first harvested black sea bass<\/em><\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Centropristis striata The black sea bass is found in Atlantic coastal waters of the United States from Cape Cod to Florida, and less commonly in colder waters north of Cape Cod.&nbsp;
