Broadband target strength of arabesque greenling, Pacific sand lance, and pointhead flounder

open access: yesICES Journal of Marine Science, 2023
Abstract Measurement of target strength (TS) is important for estimating the abundance of species using fisheries acoustics. However, most researchers have only used a limited number of representative frequencies for acoustic measurements of fish without a swim bladder (bladderless fish).

Redescription of Ammodytoides gilli, the tropical eastern Pacific sand lance (Perciformes: Ammodytidae).

open access: yesRevista de biologia tropical, 2005
Ammodytoides gilli (Bean, 1895) is the correct name for the tropical eastern Pacific sand lance. Its range is extended from Cabo San Lucas, Baja California south to Panama, Ecuador, and the Galapagos Islands. Ammodytes lucasanus Beebe and Tee-Van, 1938 is a junior synonym. Types of both nominal species were re-examined. The species is redescribed based

Feeding and food supply of juvenile fishes in the eastern Bering Sea in 2003-2012

open access: yesИзвестия ТИНРО, 2015
Feeding of fish juveniles in the eastern Bering Sea is investigated for the periods of 2003-2006 considered as relatively «warm» and 2007-2012 considered as relatively «cold». Small- and medium-sized zooplankton was the dominant prey in the 2003-2006, in

Can oceanic prey effects on growth and time to fledging mediate terrestrial predator limitation of an at‐risk seabird?

open access: yesEcosphere, 2020
Most seabird species nest colonially on cliffs or islands with limited terrestrial predation, so that oceanic effects on the quality or quantity of prey fed to chicks more often determine nest success. However, when predator access increases, impacts can

Physical Factors Affecting the Abundance and Distribution of the Pacific Sand Lance Ammodytes hexapterus in the San Juan Archipelago [PDF]

open access: yes, 2011
Anecdotal evidence has suggested in the past that the Pacific Sand Lance, Ammodytes hexapterus is present every other year in the San Juan Archipelago. This study found the fish to be present in the San Juans, as they were last year, but not as abundant

Could the planktonic stages of polar cod and Pacific sand lance compete for food in the warming Beaufort Sea? [PDF]

open access: yesICES Journal of Marine Science, 2014
Abstract The boreal Pacific sand lance (Ammodytes hexapterus) was recently detected in southeastern Beaufort Sea (Canadian Arctic), numbering as the second most abundant ichthyoplankton species after the polar cod (Boreogadus saida) in 2011. We contrast the hatching periods, growth, prey selectivity, and feeding success of the planktonic

Distribution and Phylogeny of Erythrocytic Necrosis Virus (ENV) in Salmon Suggests Marine Origin

open access: yesViruses, 2019
Viral erythrocytic necrosis (VEN) affects over 20 species of marine and anadromous fishes in the North Atlantic and North Pacific Oceans. However, the distribution and strain variation of its viral causative agent, erythrocytic necrosis virus (ENV), has ...

New insight into hybridization and unidirectional introgression between Ammodytes japonicus and Ammodytes heian (Trachiniformes, Ammodytidae).

open access: yesPLoS ONE, 2017
Based on northern (NOL) and southern (SOL) mitochondrial lineages, recently, it proposed the new species Ammodytes heian and revived the species name Ammodytes japonicus to describe sand lances from the northwestern Pacific Ocean.
