Transcriptome of the deep-sea black scabbardfish
, Aphanopus carbo (Perciformes: Trichiuridac): tissue-specific expression patterns and candidate genes associated to depth adaptation.
Tasting Madeira is savouring a glass of medium-rich reserve after a generous meal of freshly baked "Bolo do Caco" bread, limpets slathered in garlic butter, and the ugly but delicious black scabbardfish
served with passion fruit sauce.
Three main classes of fish products may be differentiated on the basis of DHA content: relatively poor DHA sources (black scabbardfish
, catfish, hake, megrim, tilapia); moderately rich DHA sources (halibut, Pollock); and very rich DHA sources (herring, mackerel, salmon, sardine), corresponding to the approximate ranges <300, 300-500, and >500 mg/100 g, respectively."
Here, you can also pick up local delicacies, including the black scabbardfish
. It might look terrifying with its large eyes and sharp teeth but when served with pineapple, it's delicious.
Bycatch and incidental catch of the black scabbardfish
(Aphanopus spp.) fishery off the Canary Islands.
In previous research, Yokoyama showed how the scabbardfish
, which today spends much of its life at depths of 25 to 100 meters, needed just one genetic mutation to switch from UV to blue-light vision.
The black scabbardfish
, Aphanopus carbo (Lowe 1839), is a bathypelagic species belonging to the Trichiuridae family and is distributed in temperate-cold Atlantic waters at depths between 200 and 1800 m [12, 13].
TACs for black scabbardfish
were raised slightly in zones BSFV, VI, VII and XII, VIII, IX, X and XII; the status quo was maintained in zones I, II, and III; and there was a slight reduction in TACs in zone CECAF 34.1.2.
Their findings on scabbardfish
links molecular evolution to functional changes and the possible environmental factors driving them.
They also formally adopted quotas for 2009 and 2010 TACs for certain deepsea fish including sharks, black scabbardfish
, orange roughy and forkbeards approved informally in October.
The "fishery" consists mainly of: 1) targeted deep-sea elasmobranch longlining; 2) targeted pelagic elasmobranch surface longlining; 3) bycatch of deep-sea elasmobranchs from black scabbardfish
, Aphanopus carbo, longlining; 4) bycatch of pelagic elasmobranchs from teleost gill-netting, purse seining, and bottom trawling; and 5) bycatch of skates and rays from crustacean bottom trawling.
