It is a demersal fish.
Demersal fish are bottom feeders.
It is a marine subtropical demersal fish.
Most demersal fish are benthopelagic.
It is a marine subtropical demersal fish, up to 25 cm long.
Many important demersal fish stocks are found in this area, including short-fin and common squids.
It is a marine subtropical oceanodromous demersal fish.
It is a demersal fish found at 70-300 m depths.
An additional scientific background chapter on demersal fish is currently being prepared.
Coastal demersal fishes live on the bottom of inshore waters, such as bays and estuaries, and further out, on the floor of the continental shelf.
CCAMLR scientific survey andcommercial finfish database demersal fish- presence/absence only.
Fisheries for straddling demersal fish stocks and other high seas demersal fish stocks are primarily conducted with bottom trawlers.
Trace metals and potential toxic elements should be assessed in muscle andtarget organs of dominant demersal fish and invertebrate species.
It is a demersal fish that lives on sandy bottoms in the eastern Indian Ocean, particularly Indonesia and northwestern Australia.
In contrast to the situation for mesopelagic fish, survey estimates of abundance are available for demersal fish in some CCAMLR statistical areas see Table 5.
Deep water demersal fish live beyond this edge, mostly down the continental slopes and along the continental rises which drop to the abyssal plains.
The Working Group noted that there are limited data available for other demersal fish in the planning area, with some species recovering from overexploitation in adjacent areas.
Demersal fish can be divided into two main types: strictly benthic fish which can rest on the sea floor, and benthopelagic fish which can float in the water column just above the sea floor.
A consequence of these energy delivery mechanisms is that the abundance of demersal fish and invertebrates gradually decrease as the distance from continental shorelines increases.
Below 600 m, the demersal fish community is dominated by gadiform fishes, including members of the Macrouridae and Moridae families and endemism was reduced compared with shallower areas.
In light of the level of uncertaintyregarding the ecology and status of these species, the Working Group recommended precaution in setting the target level for demersal fish habitat protection.
Data on diet, abundance andhabitat are more complete for demersal fish, but the inability to express abundance in absolute terms restricts the use of abundance data in ecosystem models.
The Working Group further recommended selected two-factor sensitivity analyses of the protection-level scenarios for toothfish and other demersal fish habitat as appropriate to explore a range of protection-level scenarios.
Other demersal fish stocks are the pink cusk eel, the Patagonian toothfish, the tadpole mora, the Antarctic cod, rockcods, and common squids, all of which are considered to be moderately exploited.
WS-DmPH-18/01 summarised the knowledge on the occurrence of pelagic and demersal fish species as well as krill occurrence in the wider Weddell Sea based on Soviet and German expeditions.
The Workshop cautioned that different demersal finfish can demonstrate ontogenetic changes as a function of their life-history strategy,with adult demersal fish often utilising different habitats than juveniles.
With respect to demersal fish, the Workshop agreed it would be useful to examine data sources from SCAR-MarBIN, FishBase, as well as both scientific survey and fine-scale commercial catch data that are currently available in the CCAMLR database.
One of the most salient results of such cooperation had been the prohibition of the use of trawl nets for demersal fish during mating seasons in the Arabian Gulf and for a three-month period each year.
The Working Group noted that it is unlikely that adult toothfish in the fishing grounds would be strongly associated with particular benthic invertebrate taxa, andthat a relationship with benthic taxa may be more likely for other demersal fish species or perhaps juvenile.
Succinctly, the method uses multiplefrequency echosounders to map the scattering from demersal fish, and cameras deployed from 560 a remotely operated vehicle to quantify the mixture of species and estimate their length probability distribution functions.
