Atlantic Bluefin Tuna The Atlantic bluefin tuna, Thunnus thynnus is a sleek, fast-moving giant that once lived efficiently in the world's oceans for millions of years. This marvel of evolution has endured countless hardships of climate change, predators, and shifts in prey populations, however, nothing compares to the pressures placed on the bluefin by the fishery today. It is a species in dire need of preservation. The Atlantic Bluefin tuna cruise the coasts of the Northern Atlantic and migrate
January 2009, a 440 lb Bluefin tuna sold for $173,000 (Keim, 2009). The average weight and size of a bluefin tuna is 770 lbs and 2-2.5 m.

However, these consumers may not know that they are eating endangered species. Do consumers put too much trust in the government and fisheries?

The responsible parties are national governments, fisheries, and consumers
events that starts with a simple trip to a local sushi restaurant. Eating tuna causes destruction of the ocean because of the elimination of species and it’s effects on the food chain. Eating tuna causes demand for tuna to go up. Demand for a product is defined by Reem Heakal as “ how much (quantity) of a product or service is desired by buyers” (N.D., pgh. 1).

For example, northern Bluefin tuna (Thunnus thynnus) has been documented in ocean waters ranging from 2.8to 30.6°C, while maintaining relatively constant internal body temperatures (~25°C)- up to 21°C above ambient temperatures (Block et al., 2001). In addition to water temperature
Introduction More and more species are becoming endangered every day and around 6000 are already endangered. Species endangerment is causing major issues, in our ecosystems and biosphere, as well as many other big problems that not many people realize and/or do anything to change. Even though there are many causes for extinction, the impact of habitat loss is the major reason that animals are becoming endangered and it is all our fault, the habitats being harvested for human consumption. Why Does
productivity of the land. The alarming rate of population growth and ever increasing pressure on the land have initiated an expansion of desert-like conditions into the Sahel - a process called desertification. Traditionally, the people of the drier, northern Sahel followed a nomadic lifestyle, constantly moving their herds of cattle, sheep and goats over large areas in the search for suitable grazing land. These movements prevented overgrazing and lessened the likelihood of land degradation. With increasing

INTRODUCTION The endocrine system of animals is a main source of bioregulatory compounds. Hormonal actions regulate all aspects of animal life: reproduction and development, digestion, metabolism, behavioural responses etc. (Hertenstein 2006, Norris 2007). Hormones and glands of vertebrate and invertebrate endocrine system differ in structure and function, but their main regulatory role remains conserved. However, the balance among the environmental clues, hormonal signals and organisms’ responses
