    Vegan calamari is an oxymoron.
    Tofu is not squid.

    Next time you crank up a stingray instead of your intended catch, don’t cuss it, eat it. Yes, you can cook stingray and skates. As unappetizing as they look, and as weird as their anatomy seems, stingrays (skates too) aren’t much harder to clean than your usual table varieties. And, yes, they make delicious dinners.

    Do they taste like scallops? You bet. Do some Florida restaurants serve them as scallops? I doubt it. The procurement of stingray “scallops” in restaurant quantity would cost more than buying the real thing. But it’s a good topic for debate at the dockside bar."

    You don't know what you're talking about either and neither does the article writer.
    Bottom trawling over coral? Are you nuts? Do you know what a hang book is? Or the purpose of a tickler chain? Or the lifestyles of shrimp?
    Shrimp bury themselves in mud during daylight. Tickler chains scare them out of the mud into the trawl.
    Hang books list the locations where nets have hung on bottom features previously, so they can be avoided in the now and future.
    Shrimp nets are very expensive. Hanging a net is losing the whole rig. Bottom dragging over coral, my arse!
    Benthic trawling is bottom trawling.
    Demersal trawling is near bottom trawling, and pelagic trawling is midwater trawling.
    And I drag a trynet when opportunity permits.
    It's a small doored shrimp trawl, shrimpers set out together with the big trawl, but retrieved frequently/periodically. When the trynet gets a good haul of shrimp, the big trawl is retrieved.
    The doors are paravanes that sail to the sides holding open the trawl.
    We catch shrimp in the small 30ft trynet, seaweed, a few crabs and infrequently an occasional small fish. So much for shrimping bycatch.
    We use butterfly nets, rigged like wings, for sweeping surface waters at night when shrimp come to surface. We catch shrimp, seaweed, squid, a few flying fish, occasional crabs.
    We eat what's edible.

    For a person who claims to have spent their life at sea, you certainly are not a very knowledgeable or observant person. I'm sure you will understand if we don't consider your opinion to be of much value.

    I believe you owe Myark an apology for your slanderous accusation.

    Deep-sea trawling is destroying coral reefs and pristine marine habitats
    A survey of the world's reefs and submerged mountains has revealed widespread damage from deep-sea trawling
    Deep-sea trawling is devastating corals and pristine marine habitats that have gone untouched since the last ice age, a leading marine biologist has warned.
    Deep-sea trawlers use giant, heavy-duty nets that are dragged over the seafloor at depths of more than a kilometre. The nets are fitted with rubber rollers called "rock hoppers", which destroy the corals that provide habitats for fish and other marine organisms.
    The technique was developed for use in shallow waters with smooth sea floors, but as fish stocks dwindled and technology improved, fishing fleets began using the nets in much deeper waters.

    The highest rates of incidental catch of non-target species are associated with tropical shrimp trawling. In 1997, the Food and Agriculture Organization of the United Nations (FAO) documented the estimated bycatch and discard levels from shrimp fisheries around the world. They found discard rates (bycatch to catch ratios) as high as 20:1 with a world average of 5.7:1.[8]

    Shrimp trawl fisheries catch 2% of the world total catch of all fish by weight, but produce more than one-third of the world total bycatch. American shrimp trawlers produce bycatch ratios between 3:1 (3 bycatch:1 shrimp) and 15:1(15 bycatch:1 shrimp).[9]

    Trawl nets in general, and shrimp trawls in particular, have been identified as sources of mortality for cetacean and finfish species.[10] When bycatch is discarded (returned to the sea), it is often dead or dying.[11]

    Tropical shrimp trawlers often make trips of several months without coming to port. A typical haul may last 4 hours after which the net is pulled in. Just before it is pulled on board the net is washed by zigzagging at full speed. The contents are then dumped on deck and are sorted. An average of 5.7:1 means that for every kilogram shrimp there are 5.7 kg of bycatch. In tropical inshore waters the bycatch usually consists of small fish. The shrimps are frozen and stored on-board; the bycatch is discarded.[12]

    Recent sampling in the South Atlantic rock shrimp fishery found 166 species of finfish, 37 crustacean species, and 29 other species of invertebrate among the bycatch in the trawls.[10] Another sampling of the same fishery over a two-year period found that rock shrimp amounted to only 10% of total catch weight. Iridescent swimming crab, dusky flounder, inshore lizardfish, spot, brown shrimp, longspine swimming crabs, and other bycatch made up the rest.[10]

    Despite the use of bycatch reduction devices, the shrimp fishery in the Gulf of Mexico removes about 25–45 million red snapper annually as bycatch, nearly one half the amount taken in directed recreational and commercial snapper fisheries.[13][14]

    An apprentice shrimper usually works for fish money. The rest of the crew works on shares.
    The bycatch marketable fish, the apprentice cleans and ices and sells in port. That's the only money he makes until he is useful enough to be signed on as a regular hand and get a share.

    By your figures, the hold would be full of bycatch before full of shrimp and the fishboy the richest crew member.

    One in 100 fishing trips carry impartial observers to document catch, while many are not monitored at all, leading to large gaps in knowledge and poor quality data," Oceana reported.

    The report lists the nine "dirty" fisheries as:

    Southeast Snapper-Grouper Longline Fishery - Discarded 66 percent of catch, including more than 400,000 sharks in one year.

    California Set Gillnet Fishery - Discarded 65 percent of catch as waste, including more than 30,000 sharks and rays as well as valuable fish over three years

    Southeast Shrimp Trawl Fishery - Discarded 64 percent of catch. For every pound of shrimp landed, 1 pound of billfish is discarded; thousands of sea turtles are killed annually

    California Drift Gillnet Fishery - Discarded 63 percent of catch. In five years, nearly 550 marine mammals were entangled or killed.

    Gulf of Alaska Flatfish Trawl Fishery - Discarded 35 percent of catch. In one year, more than 34 million pounds of fish were thrown overboard, including 2 million pounds of halibut and 5 million pounds of cod

    Northeast Bottom Trawl - Discarded 35 of catch. Each year, more than 50 million pounds of fish are thrown overboard.

    Mid-Atlantic Bottom Trawl Fishery - Discarded 33 percent of catch. In one year, nearly 200 marine mammals and 350 sea turtles were captured or killed.

    Atlantic Highly Migratory Species Longline Fishery - Discarded 23 percent of catch. In excess of three quarters of the wasted fish are valuable tuna, swordfish and other billfish.

    New England and Mid-Atlantic Gillnet Fishery - Discarded 16 percent of catch, including more than 2,000 dolphins, porpoises and seals were in one year.

    Myark, you didn't watch the videos I posted the urls.
    Not enough time lapsed between my post and yours.
    Probably didn't even watch the first one.
    What is a TED and a BRD Myark?

    That first propaganda video you promptly posted in reply, is a despicable worthless repeating loop, and no identification.

    I'm still downloading the 2nd video.
