This fishery also catches but discards several noncommercial species, such as the longnose lancetfish (Alepisaurus
ferox) and snake mackerel (Gempylus serpens).
It is typically present in small numbers in the stomach contents of sperm whales, Physeter macrocephalus [31-34], blue sharks, Prionaceglauca [35-38], occasionally some tunas [39, 40], and lancetfish, Alepisaurus
ferox [40, 41].
Ingestion of plastic marine debris by longnose lancetfish (Alepisaurus
ferox is distributed from the southern Bering Sea and Aleutian Islands to Chile and to Japan and the Sea of Okhotsk, as well as the Atlantic Ocean.
Taxonomic status of Pelichnibothrium speciosum Monticelli 1889 (Cestoda: Tetraphyllidea) a mysterious parasite of Alepisaurus
ferox Lowe (Teleostei: Alepisauridae) and Prionace glauca (L.Euselachii: Carcharinidae).
Randall & Dooley (1974) indicated this species was known only on the basis of the holotype from Mauritius and an additional specimen from Madras, India, lodged at the Australian Museum, although they provisionally identified South Pacific postlarval Hoplolatilus from Alepisaurus
and Thunnus stomachs as H.
Occurrence of Phronima sedentaria (Forskal, 1775) (Amphipoda: Hyperiidea) in the stomach of the longnose lancetfish, Alepisaurus
ferox (Lowe, 1833) (Aulepiformes, Alepisauroidei) in the north and tropical Atlantic Ocean.
The most commonly discarded bony fishes were the longnose lancetfish (Alepisaurus
ferox) and snake mackerel (Gempylus serpens), accounting for 28.6% and 26.7% of discards, respectively.
sp.), an amberjack (Seriola sp.), and the skipjack tuna (Katsuwonus pelamis).
In descending order of their proportion in the catch they were bigeye tuna (Thunnus obesus), longnose lancetfish (Alepisaurus
ferox), blue shark (Prionace glauca), mahimahi (Coryphaena hippurus), sickle pomfret (Taractichthys steindachneri), snake mackerel (Gempylus serpens), skipjack tuna (Katsuwonus pelamis), albacore (Thunnus alalunga), yellowfin tuna (Thunnus albacares), striped marlin (Tetrapturus audax), escolar (Lepidocybium flavobrunneum), ono (Acanthocybium solandri), and shortbill spearfish (Tetrapturus angustirostris).
Most (97%) of the fish caught on longlines belonged to 10 different species of large oceanic predatory fishes, including longnose lancetfish (Alepisaurus
ferox), four scombrids (wahoo [Acanthocybium solandri], albacore [Thunnus alalunga], yellowfin tuna [T albacares], and bigeye tuna [T.
