wind‚ creating a natural shield that helps to stop erosion. Mangroves are good breeding and nursery grounds for many fish and other animals. Many ocean fish raise their young in mangroves. Murky water in the mangroves can provide camouflage for young fish‚ making it difficult for predators to find them. Also‚ cavity between the roots of the Rhizophora tree can protect young fish from predators which are too large to enter through the roots of the tree. These ‘nurseries’ are very important for marine

total number of fish caught and landed by a fishery should be implemented. Making sure that all harvests aren’t overstepping the oceans’ replenishment speeds. Also‚ many ocean habitats must be protected. The key parts in ecosystems need full protection from destructive fisheries. Some examples could include spawning and nursing grounds of fish‚ delicate sea floor‚ unique unexplored habitats‚ and corals. These areas are vital to the constant growth and continued replenishment of fish in our oceans.

Introduction Sushi eat Tuna Introduction (let’s meet the fish) The overfishing is a common problem with some species across the sea world. The Bluefin Tuna is one of the hardest hit victim of this fishery. This specie of Tuna is located in the entire North Atlantic ocean but also in seas closed to it such as the Mediterranean sea‚ but also a strip from the equator until Norway‚ and from the Gulf of Mexico to the Black sea.

I found that the anatomy and physiology of a fish is very unique so that they can exist in the different underwater environments. In this paper we will cover their circulatory system‚ how fish sense their environment‚ and how they swim. The circulatory system of a fish is just like a humans in

We are finding that out through the catch-tag-release method (method that allows us to track the fish) that the past twelve months the population which started at 480 has dropped to 46. Three specific intervals were chosen because these intervals showed the most of how population changes throughout time. The intervals of (1‚ 472) and (5‚152) was the

just one example on how sharks keep everything in balance. Another example is coral reefs which serve as a home to thousands of fish in the ocean such as the parrot fish. Parrot fish eat coral reefs and if they don’t have a predator to control their population size it could be detrimental to the coral reefs. The parrot fish would become overpopulated and all these fish would eat away the coral reefs. (TEDxYouth). The ocean’s ecosystems would collapse without coral reefs. Many species are at risk
