HOW IMPORTANT FISHES ARE?
Fish is any various cold-blooded or ectothermic, aquatic vertebrate, having gills, commonly fins and typically an elongated body covered with scales. Fishes are abundant in most bodies of water. They can be found in nearly all aquatic environments, from high mountain streams to the abyssal and even hadal depths of the deepest oceans. According the definition above, all mammals, including Cetaceans like Whales and Dolphins, are not fish. In some contexts, especially in aquaculture, the true fish are referred to as finfish (or fin fish) to distinguish them from these other animals.
Fish is very important in terms of food, the flesh or fishes used as food. Fish is a low-fat food, a great source of omega-3 that is good for the hearth, protein, vitamins and minerals. The oils of the fish are also important for unborn and newborn babies.
Fish are the power house of an aquatic system, they provide the nutrients for the plants and if your growing edible fish, then they also provide protein for yourself.
Many types of aquatic animals commonly referred to as "fish" are not fish in the sense given above; examples include shellfish, cuttlefish, starfish, crayfish and jellyfish. In earlier times, even biologists did not make a distinction – sixteenth century natural historians classified also seals, whales, amphibians, crocodiles, even hippopotamuses, as well as a host of aquatic invertebrates, as fish.
In this modern times, it is shockingly clear that many of our own fish species that are once found in incredible numbers in the oceans are now vanishing. Habitat destruction, pollution, competition from other species/introduction of exotic species in new environments, overexploitation and over fishing are the main reasons why there are endangered fish species.
These are some of the endangered fish species in the Philippines:

| SAILFISH |
1. SAILFISH is a large tropical and subtropical marine fish. (Istiophorus Platypterus) of the family Istiophoridae, distinguished by along high dorsal fin long pelvic fins, and a double keel on each side of the tail. Its another name is basking shark. Sailfish are highly prized game fish and are known for their incredible jumps. They can appear in a startling array of colors, from subdued browns and grays to vibrant purples and even silver. Their body colors are often highlighted by stripes of iridescent blue and silver dots. Sailfish can change their colors almost instantly; a change controlled by their nervous system. The sailfish can rapidly turn its body light blue with yellowish stripes when excited, confusing its prey and making capture easier, while signalling its intentions to fellow sailfish.
2. CHILEAN SEA BASS (Dissostichus Eleginoides) is a large food fish, found in the cold deep waters of the southern Atlantic and Indian oceans. It is also called as patagonian toothfish. The Chilean sea bass is listed by the Monterey Bay Aquarium on its Seafood Watch list and pocket guides as a fish to avoid due to overfishing and high levels of mercury. Patagonian toothfish feed largely on squid, fish, and prawns and, in turn, constitute a large part of the diets of sperm whales, southern elephant seals, and colossal squid.
3. SWORD FISH ( Xiphias Gladius) is a large scrombroid fish, having the upper jaw elongated into a sword-like structure. Valued as a food and game fish. Another name of sword fish is broadbill in some countries, are large, highly migratory, predatory fish characterized by a long, flat bill. These fish can live close to shore.
4. BLUE FIN TUNA (Thunnus Thynnus) is a large tuna commonly located in temperate seas. Due to overfishing the genus has been significantly reduced, being effectively removed from some countries. Metallic blue on top and shimmering silver-white on the bottom is their color. They can swim up to 50 miles per hour when pursuing prey. They can grow up to 15 feet long and weight over 1,000 pounds. Atlantic bluefins are warm-blooded, which is a rare trait among fish, and are comfortable in the cold waters.
5. BLACK MARLINS (Makaira Indica) is one of the largest marlins and bony fish in the Pacific ocean. With a maximum published weight of 1700 pounds, but greater weights than this have been recorded. This kind of marlin is one of the fastest fish reaching the speed up to 80 mph. This kind of fish is too expensive if caught.
6. BLUE MARLINS (Makaira Nigricans) are frequently compared and confused with black marlin, especially when the fish are under 100 kilos in weight. The biggest marlins are mostly females as males only grow to around 170kilos. Blue marlins roam the tropical ad sub-tropical waters of the Indian and Pacific oceans. They are mostly found in water deeper than 100 meters and although they prefer water temperature of 24 degrees or more they can tolerate temperatures down to 21 degrees.
7. WHITE MARLINS (Tetrapturus Albidus) inhabiting the western Atlantic ocean. Pale blue above and silvery below. White marlins are elongated fish with a large upper jaw that forms a spear which is round in cross-section. Some of white marlins are large and some are small. Their average size is 20-30 kilos, same as the size of an Indo-Pacific sailfish. As of with females, they reach relatively larger size.
Three-fourths of the world's surface is surrounded by water, and this water is the home of almost 200,000 fishes. Let us not abuse God's blessing! Start conserving and protecting fishes in some little ways. Stop pollution and overfishing. Bad karma might be an outcome of our actions, because
