mackerel, common name for members of the family Scombridae, open-sea fishes including the albacore, bonito, and tuna. They are characterized by deeply forked tails that narrow greatly where they join the body; small finlets behind both the dorsal and the anal fins; and sleek, streamlined bodies with smooth, almost scaleless skins having an iridescent sheen. All members of the mackerel family are superb, swift swimmers. The firm, oily texture of their powerful muscles and their generally large size make them of great commercial importance as food fish. They travel in schools, feeding on other fish (chiefly herring) and on squid, and migrate between deep and shallow waters. The smaller species rely on the constant rush of water through their gills for sufficient oxygen and will suffocate if motionless. The largest of the family, the enormous (up to 3-4 ton/680 kg) tunas, are among the few warm-blooded fishes, due to the constant operation of their huge banks of muscles. Of the smaller members of the family, the Atlantic, or common, mackerel, Scomber scombrus, found in colder waters off North America and Europe, is one of the smallest (11-2 lb/0.675 kg average). Despite its size, the annual catch is 1 million tons, which is marketed fresh, salted, and canned. Intermediate between the Atlantic mackerel and the bonitos (see tuna) are the frigate mackerels, or frigate tunas, found in warm seas. Spotted species found off the Florida and Gulf coasts include the Spanish, painted (or cero), and Serra mackerels, averaging 10 to 15 lb (4.5–6.7 kg). Other species are the king mackerel, also called kingfish (up to 60 lb/27 kg); the chub mackerel, similar to the Atlantic mackerel; and the cosmopolitan and more solitary wahoo, or peto. The snake mackerels, including the escolars and oilfish (some species of which are sometimes marketed as white tuna or codfish), belong to the family Gempylidae. Mackerels and snake mackerels are classified in the phylum Chordata, subphylum Vertebrata, class Actinopterygii, order Perciformes, families Scombridae and Gempylidae, respectively.

Cutlass Fish


(Trichiurus japonicus), a fish of the family Trichiuridae. The naked, elongate, and silvery body resembles a cutlass. The cutlass fish reaches a length of 2 m and a weight of 1 kg. It inhabits the Sea of Japan, the East China Sea, and the South China Sea. The fish is found off the shores of India, western Africa, and Primor’e Krai (USSR). A marine school fish, it feeds on sardines. The cutlass fish has some commercial value.

Because of the presence of multiple cutlassfish species in the catch of trawlers, we identified the species that composed each sample on the basis of genetic analysis; the detailed methods and results of this analysis have been published in Wang et al.

The Argentine anchoita (Engraulis anchoita [Engraulidae]), rough scad (Trachurus lathami [Carangidae]), Atlantic cutlassfish (Trichiurus lepturus), Brazilian sardinella, and flying gurnard (Dactylopterus volitans) were the most abundant species (70% of the total biomass sampled).
The Atlantic cutlassfish and Brazilian sardinella, also abundant, displayed high frequency in the aggregations over the years ([FO.sub.T]=70% and 51%, respectively), also indicating wide distribution and persistency (Table 4).
At Los Cantiles and Isla Granito important prey were lanternfish (Diaphus sp.), northern anchovy (Engraulis mordax), Pacific cutlassfish (Trichiurus nitens), shoulderspot (Caelorinchus scaphopsis), and Pacific whiting (Merluccius productus) (Sanchez-Arias, 1992; Bautista-Vega, 2000), whereas at Isla Racito, important prey were Pacific sardine (Sardinops caeruleus), Pacific mackerel (Scomber japonicus), grunt (Haemulopsis spp.), rockfish (Sebastes spp.), and Pacific whiting (Merluccius spp.) (Orta-Davila, 1988).
We found nine main prey with IIMP average values [greater than or equal to] 10% (Table 3): the Pacific cutlassfish (Trichiurus lepturus), the Pacific sardine (Sardinops caeruleus), the plainfin midshipman (Porichthys spp.), myctophid no.
Yet, hard parts such as whole or sectioned otoliths and vertebral centra are most frequently used to age cutlassfish (Table 1).
The aims of our study were 1) to validate age estimates by using transverse sections of sagittal otoliths; 2) to verify Lee's phenomenon; 3) to evaluate the potential of using otolith size and weight to estimate age; 4) to fit the age-length data to the von Bertalanffy growth model; and 5) to provide age-growth information for management of cutlassfish resources from the South China Sea.
