It is a fact that the ocean covers 95% of the Earth. So, it is understandable that people believe we could never have marine fish in the list of endangered species. But in reality, things are far more out of control than we think. And for that, we can blame overfishing, pollution, and habitat destruction as the main cause for entire fish populations being threatened of extinction. And all of these factors are due to the action of the human being, which is not only affecting the sea fish, but the whole ecosystem.
It has been determined that 70% of marine fish that are commercially relevant are being fished to its limit of repopulation or beyond that. Most of sea fish species are being overexploited. Due to high-tech harvesting, speed boats, and acoustic detection devices, they are being caught in a rate far beyond what is advisable. In 1996, over 100 species of marine fish were classified as in danger of becoming extinct. In this list, it was included some species of tuna, several species of grouper, the swordfish living in the North Atlantic, haddock and cod fish found in the Atlantic, sole, snapper, among others. As we can see, they are all fish we eat frequently. What if we suddenly cannot have such great sources of protein and omega 3 anymore?
Apart from overfishing, we also have to consider pollution as a big factor in the whole problem. The damage caused by fish and shrimp ponds, human sewage (which causes the growth of toxic microorganisms), chemical contaminations caused by mercury, DDT, etc, coral mining, urban development, polluted coral reefs, fish being stunned by dynamite and cyanide, bottom trawling, among others, are contributing for the destruction of the marine fish habitat. On top of that, we still need to consider the climate changes, which are responsible for making the temperature of the ocean higher, and that alone can cause an enormous destruction.
However, the situation is not entirely without hope. There are some steps that once taken would put a break on the collapse of the fish populations in the sea. We could have stricter fishing limits and areas at the sea permanently closed for fishing. We would have to do something about ships on high seas being unregulated by their countries and by international laws. Also, there should be a stop to the shocking waste due to spoilage and to "bycatch", which means all the fish that were not intended to be caught or that were not licensed to fishing. With some effort, the problem can be solved. Fish can recover in a short time if compared to other animals that are in the list of endangered species, we just need to give them a hand.
Marine fish include the Acanthurus leucosternon and Acanthurus lineadae. The first breed is the Powder Blue Surgeonfish. The Surgeonfish come from the family of Acanthuridae, which dwells in the tropical Indo-Pacific Oceans. This pressed oval shape fish has a small mouth and pectoral fins. The fins are long. In addition, the fish has low, shallow notches around his caudal fins. Powder Blue Surgeonfish have black masked face, sky blue body, and yellow stripes around the lower jaw and striped down the scalpel spine. White bars contrast the multi-colors. Powder Blue Surgeonfish grow up to 11 ? inches in size.
Powder Blue Surgeonfish Environmental Preferences Powder Blue Surgeonfish prefer water temperatures at 77 degrees to 84 degrees Fahrenheit. Powder Blue Surgeonfish prefer substrate environments, as well as a pH balance at 8.2 to 9.4. Water density should be around 1.020 at all times. The tank should have good lighting. As well, the tank should be large and have a sandy bottom. The Powder Blue Surgeonfish is a good tank fish, since it feeds of algae. The downside is the fish will eat smaller creatures. The fish will also eat the flesh of Enchytraea mussels. In addition, the fish will eat particular shrimps, such as the Mysis. Powder Blue Surgeonfish will also eat dried foodstuffs, as well as vegetables.
Powder Blue Surgeonfish has a biological nature. The fish is energized and always on the run. This fish prefers to roam on his own, therefore if you attempt to put this fish in a tank with other fish, beware.
Acanthurus lineatus The Clown Surgeonfish come from the family of Acanthuridae. The fish habitats in various areas of the Pacific Indian Oceans: The Clown Surgeonfish is somewhat ugly, yet his ugliness is appealing if that makes sense. The fish has electric or powdered blue, violet, or gray-blue colors. The fish has yellow-brownish pinstripes as well. The fish grows up to 8 inches and has a narrow caudal fin. Clown Surgeonfish prefer water temperatures between 75 degrees and 82 degrees Fahrenheit. Water density is expected to be at 1.023 and the pH balance level over eight. The fish expects good light, and demands sufficient hiding corners, as well as luxury tank furnishings. The fish prefers to eat zooplanktons, and you should vary the foodstuff, since this fish does not adapt easily to aquarium foods. NOTE: Zooplanktons consist of microscopic animals, which include protozoan.
Clown Surgeonfish does not acclimatize well in aquarium environments. The fish has a nervous nature, which includes an anti-social side. The fish should reside with his own kin. You should take care when handling the Clown Surgeonfish since its spiny tail will inflict painful wounds.
The Gold Rim Surgeonfish is a family to the Acanthuridae fish, and is found under Acanthurus Glaucopareius. The tropical Indo-Pacific Ocean fish has a violent and brown tinted shade that offsets blue/orange fins. The fins have white edging that offset wide white striped cheeks. The stripes also set off the mouth and eyes. This critter grows up to 13 ? inches in size. Gold Rim fish dwell in water temperatures set between 75 and 77 degrees Fahrenheit. The pH level should be set at eight and the density should be around 1.027. You want to arrange the bottom of the tank with sand and stones, as well provide these critter good lights. The fish also demands a surplus of furnishings, as well as substrate environments. The fish demands that you provide him a variety of foods, since he is finicky. In addition, the fish has a biological nature and is known for is activeness swimming.
