The U.S. Fish and Wildlife Service and other federal and state agencies also have recovery responsibilities. The largest of the Pacific salmon, chinook (Oncorhynchus tshawytscha) average about 24 pounds when they return to their natal river to spawn, most after 2 or 3 years at sea.
· Orcas are found in all oceans of the world and favor coastal temperate or cool waters. However, they also range into polar areas. Some orca populations remain local and travel along predictable routes and others are transient and move over great distances. · Mating and birth take place mainly in autumn and winter. Gestation lasts over 12 months and at birth orcas are about 6-7 ft long and weigh almost 400lbs.
Rhincodon typus are oviparous giving birth to live young and have been documented to carry up to 300 embryos at one time. Female whale shark’s will give birth to numerous batches of pups in short succession and may rest up to a year after giving birth before mating again. The large size of the litter and rate of birth suggests a very high rate of neonatal mortality. Young pups will stay with their mother for an undetermined amount of time until they are
Finally, the adult T. palmi will break out of the pupa stage, start its feeding and subsequently, reproduction (Cannon et al., 2006). An adult T. palmi tend to live for 17 days on average (Seal, 2004). b. Geographical distribution and pest status T. palmi was originated from Sumatra, Indonesia but it has now spread to many parts of the world. Below is the list of countries T. palmi are found: Asia: Bangladesh, Brunei, China, India, Indonesia, North & South Korea, Malaysia, Myanmar, Pakistan, Philippines, Singapore, Sri Lanka, Taiwan, Thailand Africa: Mauritius, Nigeria, Reunion, Sudan Caribbean:

People who fish these endangered fish will have their jobs saved. This will also produce more fish for the individuals who have fish as their main source of food in their diet. The definition of overfishing is to fish so heavily that you wear out the supply of edible fish. The amount of fish that are fit for human consumption in our waters is decreasing because of our world’s overfishing problem. In a study done by international team of scientists, by 2048 almost all edible fish in the ocean will be gone (“Go Fish”).
The average person consumes approximately two dozen eggs per month ("The 2013 Russell Research Egg Board Advertising Tracking Study Executive Summary" 2016). The current average family size is 3.1 people ("Changes in Household Size" 2015). With information known about egg consumption and average household size, we can assume the average family will consume approximately six dozen eggs per month. The King family would like to produce sixty dozen eggs per month, which would include amount consumed by their family and enough to provide eight other families with eggs. The average chicken lays approximately 325 eggs per year, which is 6.25 eggs per week ("Purdue Food Animal Education Network" 2016) .
Zebra Mussels are a threat to ecosystems. They damage the natural habitat of lakes and rivers and cause negative effects to the native aquatic life. They multiply in vast majority casing a lake of food and space for other animals. And also the U.S. has spent millions on the removal of these pests from our water (“Zebra Mussels,” 2014, para. 8).
The dorsal spine normally is held erect when the fish is excited and a tennis shoe or even a leather-soled shoe offers little protection. Adults may reach two pounds or more, but the average is about 10 inches and half a pound.

Their population has been very low statewide since 1983 It got to the point where the fishery crashed and the top four producing areas were closed to red king crab fishing. After this had happened, fisherman had attacked or targeted the golden king crab.
