Scientific advice further indicates that orange roughy in subarea VI is heavily depleted, and areas of vulnerable aggregations of that species have been identified. |
|
Most sub-populations contain many spawning aggregations or demes. |
|
In the water column above the northern continental slope and the upstream end of the Laurentian Channel, euphausiids form large aggregations that are exploited by cetaceans. |
|
Similarly with the offshore dragger fishery, the catch rates in that fishery were used with the research vessel survey data as though they were not based on fishing on aggregations and following the fish. |
|
During the periods when anadromous fishes are migrating into or out of fresh water, they form large aggregations in estuaries, awaiting the changeover in their osmotic regulating systems. |
|
|
However, it may be that in an area of 1600 m2 the population of Sincyonis tuberculata is distributed in small aggregations that are arranged in a random fashion according to Poisson's law. |
|
Actually, however, each of these huge spawning aggregations is made up of small, coordinated parties consisting of one female and one or more males. |
|
Generally, it appeared to me that such aggregations made empirical sense. |
|
The tool can generate reports at various levels of aggregations as well as comparative reports on the financial impact of options considered, thus supporting decisionmaking. |
|
We feel also that scientists and stakeholders agree there are significant inshore aggregations, particularly in the central core area of which I have already spoken. |
|
South of Anticosti, the northern stone crab forms aggregations generally located deeper than 300 m, except on sandy beds, where it can be found in shallower waters. |
|
Such aggregation procedures are sometimes presented as superior to the monetary aggregations that are used for building economic indexes, because they are not linked to any form of market valuation. |
|
This is an exceptional fact, because what usually happens in large economic aggregations is that, unless there is a strong policy in place, the richer areas get richer and the poorer areas get poorer. |
|
I have long felt that this should be done at the local level, with national, European or global aggregations done from time to time through a random sampling of localities. |
|
The deep waters around the Azores, Madeira and the Canary Islands host coral aggregations, thermal vents and carbonate mounds which give shelter and food to diversified fauna and flora. |

Closely related matrilines form loose aggregations called pods, usually consisting of one to four matrilines. |
|
An exception to this is the walrus, where females form dense aggregations perhaps due to their patchy food sources. |
