Apropos of the present review, these authors found that Pacific hake (as well as other important gadoids
in the Gulf of Alaska, walleye pollock, Theragra chalcogramma, and Pacific cod, Gadus macrocephalus) appeared to respond more strongly to interannual variability than to decadal climate variability, and they had a statistically higher proportion of strong year classes in unusually warm years than in other years.
Other important gadoid
species are haddock (Melanogrammus aeglefinus), whiting (Merlangius merlangus), blue whiting (Micromesistius poutassou), hake (Merluccius), pollack (Pollachius virens), and flatfish such as the European plaice (Pleuronectes platessa), common sole (Solea vulgaris), lemon sole (Microstomus kit), flounder (Platichthys flesus), brill (Scophthalmus rhombus), and turbot (Psetta maxima).
Work by Engas and Godo (1989a) indicates that the effective width of a demersal trawl used for sampling gadoids
is related to fish size.
The use of species-specific TaqMan probes for identifying early stage gadoid
eggs following formaldehyde fixation.
Hislop (1984) summarized fecundity data for four gadoid
species from the North Sea and estimated FGB for cod, Gadus morhua, and haddock, Melanogrammus aeglefinus, at 475 and 550, respectively.
The conclusions of this study cannot be categorically accepted for all species in both commercial and research situations; however, there is no reason to doubt that the conclusions would hold for the majority of gadoid
species along the Atlantic coast.
Bromley (1989) found a negative relationship between density and growth in some gadoid
(Atlantic cod, whiting, and haddock) juveniles in the North Sea.
Importance of the swimbladder in acoustic scattering by fish: A comparison of gadoid
and mackerel target strengths.
Identification of gadoid
species (Pisces, Gadidae) by PCR-RFLP analysis.
These techniques have been applied to the identification of numerous species of fish and seafood, including gadoids
, flatfish [15, 16], salmonids [11, 104], scombroids [105, 106], sardines and anchovies [107, 108], eels , and mollusks [110, 111].
When fish meet a trawling vessel: examining the behavior of gadoids
using a free-floating buoy and acoustic split-beam tracking.
The square-root model has been observed to adequately describe the GE of different gadoids
(e.g., Jones, 1974; Temming and Herrmann, 2003), pikeperch Stizostedion lucioperca (Koed, 2001) and coho salmon Oncorhynchus kisutch (Andersen and Beyer, 2007).
