Morphological and molecular diagnosis of Anisakid nematode larvae from cutlassfish (Trichiurus lepturus) off the coast of Rio de Janeiro, Brazil.
Three new species of monogeneans parasitic on Atlantic cutlassfish Trichiurus lepturus (Perciformes, Trichiuridae) from Southeastern Brazil.
New Species of Metacaligus (Caligidae, Copepoda) Parasitic on the Cutlassfish (Trichiurus lepturus) of Taiwan, with a Cladistic Analysis of the Family Caligidae.
Reproduction of the cutlassfish Trichiurus lepturus in the southern Brazil subtropical convergence ecosystem.
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.
The main species responsible for the difference in assemblage structure between the SACW and the combination of CW and M (CW+M)--the species that cumulatively accounted for ~75% of the difference--were the Argentine anchoita, Atlantic cutlassfish, rough scad, piquitinga anchovy, and white snake mackerel (Thyrsitops lepidopoides), all of which were most abundant in SACW, and the Brazilian sardinella, flying gurnard, false pilchard (Harengula clupeola), American coastal pellona, and Atlantic thread herring (Ophistonema oglinum), all of which were most abundant in CW+M (Table 6).
During a parasitological survey, numerous specimens of monogenean parasitic on cutlassfish from Guanabara Bay were collected in the Rio de Janeiro State, Brazil, and three new species were described in the present paper.
Metazoan parasites of the Atlantic cutlassfish, Trichiurus lepturus (Osteichthyes: Trichiuridae) from the coastal zone of Rio de Janeiro State, Brazil.
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.
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.
The importance (IIMP) of the Pacific cutlassfish was greater in Los Cantiles (28.
In terms of weight, cutlassfish is the most important commercial marine fish species in China (Luo, 1991) and has accounted for about 10% to 20% of the total marine fish catch.
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.
