On top of that, leaking fuel has repeatedly threatened the spawning areas of the shrimp.
此外,煤油的泄露会危及虾的产卵区。
Technologies like fish ladders help salmon go up over dams and enter upstream spawning areas, but the presence of hydroelectric dams changes their migration patterns and hurts fish populations.
Marine areas considered as vulnerable include: critical habitats, including coral reefs, wetlands, seagrass beds, coastal lagoons and mangrove forests; habitats of endangered species; ecosystem components, including spawning areas, nursery areas, feeding grounds and adult areas; shorelines; coastal watersheds; and estuaries.
Well, based on our work in the United States and elsewhere, we know that there are three key things we have to do to bring fisheries back, and they are: We need to set quotas or limits on how much we take; we need to reduce bycatch, which is the accidental catching and killing of fish that we're not targeting, and it's very wasteful; and three, we need to protect habitats, the nursery areas, the spawning areas that these fish need to grow and reproduce successfully so that they can rebuild their populations.
In the best spawning areas, there are thousands of salmon in every mile of river.
在最适宜的产卵区域 每英里水域能有上千只马哈鱼
Fish stocks have a geographical closure of their life cycles, in which spawning migration to defined spawning areas, drift of fish larvae to suitable nursery areas and feeding migrations of juvenile and adult fish are major components.
The criteria include areas with habitats of endemic, rare or threatened species and communities of fauna and flora; habitats of migratory species; nursery and spawning areas; and rare, unique or representative geological or geomorphological structure processes.
New Zealand proposed the establishment of a marine protected area in CCAMLR, in the Ross Sea region, aimed at protecting the full range of marine habitats, including juvenile habitats and spawning areas of the Antarctic toothfish.
