Here are some general guidelines for baking salmon. 1  A good rule of thumb is that at 350 degrees the salmon will bake about ten minutes per one inch thickness of your fillet. 2  A two-inch thick fillet will bake for 20 minutes. 3  A 1-1/2 filet will take 15 minutes and so on.
In the United States, there are over 230 amphibians, over 280 reptiles and approximately 800 species of fish. Each of these categories has species represented on the US Endangered Species List. Together, more than 170 amphibian, reptile and fish species are threatened or endangered.
The greatest species diversity exists among insects, which account for about one million of the earth's species known to science. Mammals make up one of the smallest groups, with just 5,513 members. Altogether the earth's oceans, lakes, continents and islands support over 66,000 identified species of vertebrate animals and more than 307,000 species of plants. The species totals do not include domestic animals such as sheep, goats and camels. Nor do they include single-celled organisms such as bacteria.
