12.2. Problems in Habitat
Management
Offshore Problems:
offshore oil and gas developments, bottom debris, closure of
fishing areas, over fishing, pollution from ships, oil tanker
disasters, ocean dumping, and ocean contaminants over fishing,
harvesting methodology. |
| Coastal
and Estuary Problems: shipping disasters (such as the
Kurdistan), contamination of oyster beds, lobster grounds, and
other fish in general, by sewage, mine tailings, contaminants
(e.g. cadmium) and other industrial wastes; destruction of nursery
and fish rearing areas caused by causeway construction, tidal
power, thermal plumes from electrical generating stations, port
dredging and dumping, and shipping activities. |
Each
part of Nova Scotia has unique problems determined by the
types and locations of fish in relation to pollutant sources,
and competing uses of the ocean fishing grounds, coastal zones,
estuaries, rivers and lakes. |
| River
and Stream Problems: industrial pollution, stream alterations
(1500 per year), acid rain, chemical spraying, agricultural
and forestry practices, hydroelectric installations, watershed
development projects, silt and sand input and high peak flows
from poor land use, and gravel removal. These problems are covered
in more detail in earlier sections of the manual. |
