Lion Fish

 

The Life of Animals | Lion Fish | Pterois range in size from 6.2 to 42.4 cm, with a typical adult measuring 38 cm and weighing an average of 480 g. Youth Lionfish have a tentacle above single sockets of his eyes, ranging in phenotype among species. According to a study of the decomposition of more than 1,400 lionfish stomachs from Bahamas to the waters of North Carolina involved, Pterois prey mainly on small fish, invertebrates and shellfish in large quantities, with a number of copies of the stomach of more than six different prey types. The amount of Lionfish prey in stomachs during the day suggest that the most active feeding lionfish 7:00 to 23:00, with reduced power during the afternoon.

The lionfish, then spread their large pectoral fins and swallows its prey in a move singe researchers also noted that the jets blowing lionfish, while the prey approaching, apparently next to disorient the subject case of larger lionfish engaged in cannibalism in smaller individuals, identified adult lionfish have few natural enemies. Morays (family Muraenidae) Bluespotted horn fish (Fistularia commersonii) and large groupers, such as tiger grouper (Mycteroperca tigris) and Nassau grouper (Epinephelus striatus) were observed preying on lionfish. It remains unknown, but the question of how often these predators prey on lionfish. Sharks are also believed trapped in lionfish, without damaging their spines.

Park officials Marine Park Roatan in Honduras attempted to train sharks to feed on Lionfish in 2011 in an attempt to weed populations in the Caribbean, the arrival. Predators of larvae and juvenile lionfish remains unknown, but may be the main factor limiting the lionfish population in its own range. Lionfish parasites are rarely seen and is believed to have been frequent. They include isopods and leeches Lionfish are known for their venomous spines, a feature that is unusual among marine fish on the reefs of the east coast. The lionfish is a predator of the Indo-Pacific. The aggressive prey, small fish and invertebrates. Lionfish usually have a hostile attitude and are territorial to other reef fish.

 Two of the nine species of Pterois, the red lionfish (P. volitans) and the common lionfish (P. miles) have established themselves as a major invasive species on the east coast of the United States and the Caribbean. Approximately 93% of the population is invasive P. volitans. The red lionfish is found on the east coast of the United States and the Caribbean Sea, and was likely first introduced off the Florida coast in the early and mid 1990. It is also believed that lionfish were purposely discarded by aquarists displeased. The first documented capture of Lionfish in the Atlantic occurred in Dania Beach, Florida. In 2001, NOAA documented sightings of lionfish off the coast of Florida, Georgia, South Carolina, North Carolina and Bermuda and the Bahamas were discovered in 2004.

Pterois volitans and Pterois miles are tropical and subtropical regions of southern Japan and South Korea to the east coast of Australia, Indonesia, Micronesia, Polynesia and the South Pacific. Pterois are known to devour many other aquarium fish. Pterois are unusual in that they are among the few species that successfully established populations in open marine systems. Extreme temperatures have limited geographic distribution of aquatic species, indicating that the temperature tolerance plays a role in the reproductive survival lionfish, range and distribution.

Pterois extended along the entire east coast of the United States occupied and suitable thermal zones within ten years, although the timing of observations points to the east coast of Florida, as the original source of the invasion of the western Atlantic, the relationship of the United States East Coast and Bahamas lionfish invasion is uncertain

The population of the invasive lionfish is growing very rapidly, and efforts are underway in several areas of control. However, the lionfish completely eradicate their new habitat seems unlikely. A study in 2010 with the population models used data collected on the known life history of the lionfish inhabit the coral reefs of the Caribbean to determine the best means to eradicate. The study showed that the most effective way to even maintain current lion population at least 27% of adults should be killed invasive monthly. In November 2010, the Florida Keys National Marine Sanctuary began issuing licenses for divers to kill lionfish in the sanctuary.

Serious and repeated removal of water penetrating the lionfish will need to gain control of exponentially growing populations of conservation in many eastern U.S. are organizing hunts for Pterois. Community organizations formed around the country hoping to stop the growing population lionfish. Based on average kills per dive, a diver can easily kill Lionfish 3000-4000 per year (3 dives per day, six days a week, averaging 4 + kills per dive). Many people are wary of the idea of eating a poisonous fish, fish fillets properly but is perfectly healthy to eat. Encourage the consumption of lionfish not only help maintain a reasonable population density, but also provide an alternative source for other fish stocks overexploited, like grouper and snapper.

NOAA calls the lionfish a delicious flavor, delicate fish "texture for grouper. Many recipes for lionfish can be found in cookbooks from the coast, including some fried lionfish, lionfish ceviche, grilled jerky lionfish and lionfish. NOAA is also planning to continue his "Fish as Food Lion" campaign, as human hunting, fish is the only known form of the current control. NOAA also encourages people to report lionfish sightings to help spread a better record keeping Lionfish have successfully completed the coastal waters of the Atlantic, pioneered in less than ten years and are a major threat to ecological systems reefs in these areas. An environmental impact caused by Pterois could their impact on population numbers of prey by directly affecting the relations of the food chain. Studies show that the lionfish's Atlantic reef diversity may decrease to 80%. In July 2011 Lionfish were first reported in Garden Banks National Marine Sanctuary off the coast of Louisiana Flower.

China Shark fin with Bands of High

 

  

The Life of Animals | China Shark fin with Bands of High | Young Chinese gangs shark fin high usually have brown bodies which bears three dark bands tilted. Adult males are distinguished from adult females by their red color. Chinese shark fin high bands are also characterized by high dorsal fins triangular and extending upwardly to the rear of the anal fin. Lips thick and fleshy papillae small bear, with no chins. In adulthood, Chinese shark fin band becomes darker in appearance. In old age, it loses its characteristic white stripes. Chinese high fin shark bands are native to the Yangtze River basin of China in Asia. Chinese high fin banded shark can only thrive in cold water aquariums. Chinese shark fin high bands thrive in a tank with water temperature ranging from 65 ° to 75 ° F (24 ° C) and boiling water pH 6.0 to 7.5.

Chinese gangs shark fins are of high middle and bottom of the tank inhabitants. We know that change color depending on your setup. They are compatible with rasboras, danios and Siamese algae eaters. Chinese high fin shark researchers bands are common foods. Males are known to acquire tubercles on the head and wings, once they reach sexual maturity

Knifefish Spirit Black

  

The Life of Animals | Knifefish Spirit Black | Fish knife requires a black ghost tank dimensioned 30-40 U.S. gallons (95-110 liters) a lower, but as they grow requires a much larger tank around 80-90 + U.S. gal. prefer a tank with low light because their vision is optimized for low light conditions. to help them to do, which is a weakly electric fish. eat small fish tank and are intolerant of their peers. like fish without scales, which are vulnerable to parasitic infections, such as ICH (Ichthyophthirius multifiliis). can reproduce in captivity, although there are few reports of Black ghost knife fish. The black ghost knifefish, Apteronotus albifrons, is a tropical fish belonging to the ghost knifefish family (Apteronotidae).

Grow to a maximum length of 20 inches (50 cm). The black ghost knifefish native lives in fast moving streams, the sandy bottom in a tropical climate. South American natives believe that the ghosts of dead fish of his residence, hence the name.

Boeseman The Rainbowfish

 

  

The Life of Animals | Boeseman The Rainbowfish | Boeseman Rainbowfish lives in the western part of West New Guinea (formerly Irian Jaya). Boeseman Rainbowfish is not only present in Ayamaru lake also found in Hain Aitinjo lake and pond, as well as the currents flowing into the lake Ayamaru. Both Hain and Lake Aitinjo lake is 20 km (12.5 miles) Lake Ayamaru. The Rainbowfish Boeseman typical habitat is shallow and marshy with clean water and abundant aquatic vegetation. Boeseman Rainbowfish is threatened by overexploitation, as it has become a popular aquarium fish. In late 1980, about 60,000 men specimens exported from the Great Lakes Region Ayamaru each month. Boeseman Rainbowfish is listed as "Endangered" in IUCN Red List of Threatened Species. Boeseman Rainbowfish is not difficult to maintain in the aquarium and is a popular aquarium fish, even outside Australia.

 

You can keep in a species of rainbowfish aquarium Boeseman or combined with peaceful species of similar size in a community created. Try to remember the natural habitat in the aquarium Rainbowfish Boeseman and include a large number of lush plants. Recommended Water temperature is 25-30 ° C (77-86 degrees F). The water should be alkaline, pH 7.2 to 8.0. Let the chlorine evaporates the water before using it for water changes, if you use chlorinated water. Keep your fish a varied diet containing foods alive. Rainbowfish Boeseman may well survive on dry food only, but will not thrive and they can lose their vibrant colors. The Aquarium L 50-75 (13-20 liters) is large enough to serve as breeding aquarium for a small group with a single male. Feeding large quantities of live fish meat food.

Males can be aggressive with females during the breeding season, so a well planted aquarium and proper sex ratio are important. A higher temperature water can accelerate the process. You can feed the fry infusoria, egg yolk and finely ground flake food until they are large enough to eat brine shrimp newborns and nibble flakes integrals.

Spotted Gar

 

  

The Life of Animals | Spotted Gar | Although the Great Lakes basin to understand the extent to Northern Spotted Gar in the United States, the basins are the southern basin of Lake Michigan, Lake Erie basin and southern basin of Lake Huron. The population is small gar in the north and Lake Erie is threatened by habitat destruction and pollution. The gar is most common in southern waters, such as the Mississippi River basin from southern Minnesota to Alabama and West Florida at the time. Historical records indicate the gar was spotted in the Thames River and Sydenham River, Ontario, Canada. Nesting habitat includes wetlands and swamps with an abundance of aquatic vegetation. Even surface water is preferable to estimate approximately 0-1 m water depth A female can have multiple mating partners and the female is usually larger than males mate with.

The females have lower mortality rates of up to an annual gar is 18 years. Men today are having an impact on this species of fish, destroying habitat, aquatic vegetation, and the creation of sedimentation in the waters of North America. Waste and drainage chemistry in lakes and rivers causes the accumulation of chemicals and water contamination. Spotted gar or pools of clean water, and human factors can reduce their survival. the Canadian waters of the spotted gar is protected by the Endangered Species Act and the Federal Fisheries Act. The Program Management of species at risk habitat works to protect the spotted gar and their habitat. Current management plans for spotted gar include: increased water quality, minimize or prevent pollution, the analysis of samples contaminated with the decline of the most important biological species is habitat destruction. Firstly, without the need for gar habitats can not grow and reproduce normally consequent reduction of the population.

Electroshocking would be held in the shallow areas of lakes and rivers where gar habitat. The sampling for the monitoring of the species would be to monitor visually. The fishermen can fill out surveys for spotted gars many who have taken or bow fishermen spotted gars tell you how many shots all the time. Technology as an underwater camera can be used to search for spotted gar. Some shallow areas may be prohibited for fishing and areas could be sampled to compare the population of fishing. Spotted gar have few predators threatening invasive species so that there are fish and should be removed. Port improvements, dredging filling, and destruction of coastal habitats affect fish and should be stopped. Water quality must have a certain level of quality and biologists should verify the frequency levels and to address whether the level is low quality.

Research in the main streams must be performed on tissue samples for testing gar contaminants. Spotted gar is not a popular game fish species for fishermen, but fishermen are a kind of value the bow to shoot. Promotion of a gar fish would help conserve the species.

Reedfish

  

The Life of Animals | Reedfish | Reedfish are curious, peaceful, and some have "personality". Once you have an other peaceful fish that can "intimidate" a Reedfish, despite its large size, especially if there is competition in the fish tank for food or space. An easy way to verify if the Reedfish have the need is to put a tank farm with a lid on the tank, which will soon make their nests on top if necessary. The fish are known escape artists and can jump a distance so great, the tank must have a well-fitting lid, without large holes; inexperienced aquarists have saved their drying Reedfish after finding her on the floor just Reedfish vivo. It is preferable to reduce the water level, if you can not completely seal the tank.

 

Reedfish in captivity more readily accept bloodworms and other frozen foods that go to the bottom of the tank. If kept with other fish to eat fast, you better put Reedfish food in a narrow tube that only he could get, or feed him bloodworms hand. Although there have been people who were adults in small tanks of 100 liters, which do best in large tanks. Water must not be very pure and clean as a Reedfish natural habitat is often low and well-nourished with oxygen, however, other fish in the tank may not be compatible with water slightly impure.

Sockeye salmon

  

The Life of Animals | Sockeye salmon | Sockeye salmon ranges as far south as the Columbia River in the eastern Pacific (though individuals have been spotted as far south as the 10 Mile River on the Mendocino Coast of California) and northern Hokkaidō Island in Japan in the western Pacific, and as far north as Bathurst Inlet in the Canadian Arctic in the east and the Anadyr River in Siberia in the west. Nantahala Lake is the only spot in North Carolina where Kokanee salmon are found. Sockeye spawn mostly in streams having lakes in their watershed. The young fish, known as fry, spend up to three years in the freshwater lake before migrating to the ocean.

Some fish spend as long as four years in fresh water lakes before migrating. In rivers without lakes, many of the young move to the ocean soon after Hatching. The return Abundance (population) of Fraser River sockeye in 2009 was estimated at a very low 1,370,000, 13% of the pre-season forecast of 10,488,000. The Reasons for this (former) decline REMAIN speculative. The evidence indicated this reduced productivity Occurred after the juvenile fish began Their migration to the ocean.

Astonishingly, the number of sockeye returning to British Columbia was around 30 million in 2010, the largest sockeye run in 97 years, in bizarre contrast to the low Unexpectedly run in 2009. The Abundance of sockeye stocks in 2010 are estimated to be over 260% higher than the predicted 11.4 million salmon.  Sockeye is an exception to 2010's forecast Oregonian Resurgence of fish stocks. The sockeye population peaked at over 200.000 in 2008 and were forecast to decline to just over 100 000 in 2010. As an early indication of the Unexpectedly high sockeye run in 2010, on July 2, 2010, the United States Army Corps of Engineers reported over 300 000 That sockeye had passed over Bonneville Dam on the Columbia river. Lower temperatures in 2008 in North Pacific waters Brought fatter plankton which, along with the Greater outflows of Columbia River water, feeding the resurgent Populations

Proposed Legislative Efforts Such as the Northern Rockies Ecosystem Protection Act are Attempting to protect the Headwaters of the sockeye salmon by Preventing industrial development in roadless areas. U.S. sockeye salmon Populations are currently listed under the U.S. Endangered Species Act by the National Marine Fisheries Service as an endangered species in the Snake River (Idaho, Oregon and Washington area) and as a Threatened species in Lake Ozette, Washington. Other sockeye Populations in the upper Columbia River and in Puget Sound (Washington) are not listed under the Act.
