Concern over the well-being of marine mammals at sea has focused on intentional harvests, both in terms of individual welfare and population sustainability. Unintentional mortalities from fishing gear entanglement are primarily seen as a risk to population viability. Additionally, larger whales breaking free of, and subsequently carrying, fixed trap and net gear are subject to a very slow demise, averaging 6 months in the case of the North Atlantic right whale (Eubalaena glacialis). Chronic cases can involve impaired foraging, increased drag, infection, hemorrhage, and severe tissue damage. The individual suffering of these cases appears to be extreme. Thus management measures should go beyond legally mandated conservation measures to include avoidance of such scenarios. Seafood consumers could succeed, where laws have failed, to demand fishing practices that do not kill whales in this manner. The effective absence of such demands would seem to reflect the cryptic nature of these cases to most consumers.

Zinc Deposits

Small iron-formations in Grenville metasediments have been examined as possible lateral stratigraphic equivalents of stratiform zinc deposits located along the western margin of the Mount Laurier Basin in the Maniwaki–Gracefleld area, Quebec. Similarities in carbonate and amphibolite units hosting the iron and zinc deposits tend to confirm this concept. Sphalerite sparsely disseminated along a dolomitic bed adjacent to the iron-formations, and the iron-formations themselves, are interpreted as the distal extremities of the massive sphalerite lenses found in the proximity of thick amphibolitic strata close to the (fault-bounded?) basin margin. A submarine exhalative model generating proximal zinc and distal iron deposits is proposed to explain this metal zoning. Originally the iron-formations probably consisted of sedimentary siderite that has been transformed under intense metamorphism to the present magnetite–graphite assemblage.
