Mapping alter inwards weight, length, too abundance of Pacific Halibut: 1998 - 2015 visualizes 2 quantifiable facts nearly halibut stocks inwards the survey areas. The colored circular markers present both the full pounds of halibut (size of marker) too the per centum of halibut over 32 inches (color of the marker). This way that users are able to easily visualize the falling numbers of halibut too the reduction inwards size of the fish.
This reduction inwards size too numbers of Halibut inwards the Pacific is reinforced yesteryear the overall numbers inwards each survey area. If you lot hover over a regulatory surface area on the map you lot tin grade the sack sentiment the give away of halibut, the full pounds of halibut too the per centum over 32 inches for the selected year.

The skillful word is that halibut numbers inwards the end few years accept improved inwards many of the regulatory survey areas, specially inwards those along the westward coast of Canada too the USA. This is belike due, to around extent, to the conservative administration of fish stocks over the end decade.
This halibut stocks map was created yesteryear Lis Fano. You tin grade the sack sentiment to a greater extent than of her maps on her online portfolio.
