In this episode of "real or fake" you can test your skills on 5 pictures and videos send in by viewers just like you. First off we have a video that claims to show a whale that beached itself in France, then we have a picture of a frog that looks like something from the olympics, another picture of a zombie koala bear, and a bizarre little spider that looks like something from a pokemon game. And for the big story this week, a photo that claims to show a giant godzilla of a fish!
Whales, frogs, koala bears, spiders, and fish. Who could ask for more. Other than a bunnny harvestman, shortraker rockfish!
More about Shortraker Rockfish
Shortraker rockfish -Sebastes borealis- is an offshore, demersal species distributed from the southeastern Kamchatka Peninsula, Russia, to Fort Bragg, California. It attains lengths greater than one metre 39 inches and weighs up to 20 kg 44 pounds. In the Gulf of Alaska, shortraker rockfish are sampled annually during longline surveys and are most abundant between depths of 300–400 metres or 980–1,310 ft.
Commercial harvesting in the Gulf of Alaska began in the early 1960s when foreign trawl fleets were targeting more abundant. In recent years, high catch rates indicate that the domestic trawl fleet targets this species; shortraker rockfish comprised 14.9% of the species composition of slope rockfish harvested in 1990, although trawl survey data indicates they comprised only 2.5% of the biomass.
In 1991, catch limits were established for shortraker rockfish to prevent overharvesting of this species in the Gulf of Alaska. Catch limits are based on biomass estimates derived from bottom trawl catch rates. These biomass estimates are questionable, however, because the catch efficiency of bottom trawls on shortrakers is unknown. Fishermen report that shortrakers school off-bottom and above rugged habitat in steep-slope areas where bottom trawls cannot sample effectively.
