Flounder can usually be found in Canada as well as on the eastern coast lines of America. They are known to feed on mussels, insects, and fish spawn, which they usually be found along the span of the ocean floor, on docks, on foundations of bridges that span across water forms, and along bass grounds.

There are, right now, three common types of flounder. These are the left eye flounder, the right eye flounder, and the Southern flounder.

The Uses of Flounder

Flounder is best used as food as well as for hobby fishing. The best season for catching flounder for food is during the spring or fall seasons, because these are the seasons when the flounder is typically at their best. When one catches flounder during the summer season, one may notice that the meat does not taste as well and is irritatingly soft.

The best way for cooking flounder is by pan searing or frying. Flounder is also great when baked, as well as when it is stuffed and then cooked.

On the other hand, when fishing for flounder, it is advisable to make use of a small fishing hook, preferably a number 8. If the shores have plenty of flounder in it, catching should basically not be a problem, since this type of fish will bite on to almost any bait a fisherman uses. The best places to fish for flounder is on the inlets of New Jersey, as well as in Boston and along the New York Bay and Long Island.

Wonderful Elongated Fishes

The Elongated Fishes

Believe it or not, according to taxonomy or animal classification or categorization, though they look like snakes, eels are fishes as well. Based on scientific studies, there are more or less, 800 species, 110 genera, 19 families and four suborders that identify eels. In terms of the eels' practical usages for humans, eels are favorite food in some cultures. Japanese, Korean and Chinese traditions consider eels as a popular cuisine (like Unajuu and Unadon) that is in a way very expensive. In Hong Kong, a kilogram of eels could have a tag price reaching a 1000 HKD. Eels had been considered an aphrodisiac and stamina booster in some cultures and traditions and that had been one of the reasons why they are fondly consumed by humans. Freshwater eels like the European eels are also a delicacy in United States and some European countries and regions. Jellied eels have been a desired traditional east London food before the Second World War. The 'angulas' is a Basque dish that contains deep-fried young eels or elver. A taste for these deep-fried eels would definitely cost a fortune: a kilogram of elver would cost up to 1000 euro. The Maori is a New Zealand dish that has New Zealand longfin eels. According to research, the blood of eels is lethal for some mammals and humans as well. Nonetheless, due to digestive and food preparation processes, the toxin protein is being destroyed as well.

How Long is This Elongated Fish?

In terms of sizes, measurements or dimensions; eels are gauged in terms of their length. In average, eels' length is ranging from two inches (or five centimeters) up to 12.3 feet (or 3.75 meters). In terms of their average heaviness, an adult eel could weigh from thirty grams to more or less 25 kilograms. Though, in a way or two, they are considered as fishes; eels have some distinct characteristics from the fishes. Unlike fishes, eels do not possess pelvic fins and some types lack pectoral fins. Eels' anal and dorsal fins are amalgamated with the tail or the caudal fin that form a single strip running along the majority of the eels' length. Sea holes, the bottom layer of the ocean and shallow waters are the preferred dwelling places of the eels. These sea creatures are really fond of swimming.

Some Recent Facts and Concerns

The American eel, the European eel and the Japanese eel are categorized at the seafood red list by the Greenpeace International in 2010. The seafood red list of Greenpeace international is a record of fishes that are regularly sold in supermarkets all over the world and that have a very high danger of being supplied by untenable fisheries.

Detail Information about Turbot Sizes

When it comes to big creatures that can be found at seas, many people will include turbot sizes on their search. This species can be found at the waters on the North Atlantic, the Baltic Sea, Black Sea and Mediterranean Sea. This can also be seen at marine and brackish waters. The name was derived from the Swedish word torn but, which means stump. It has gotten into the English and French language around the 13th century. Historians say that various turbot sizes were consumed by the Romans. This was due to the poem by Juvenal that was written around the early 2nd century AD or around the latter part of the first century. The poem mentioned this species, which has become the evidence of historians.

How to Maintain Pond And Controlling Algae

You have taken great time and expense to build your Koi pond. You have taken even more time in selecting and stocking your Koi fish. All of these great efforts will be in vain if you do not adhere to proper Koi pond maintenance. Such maintenance involves all aspects of your pond's condition; from controlling algae in ponds to oxygen levels and water changes.

Your Koi pond maintenance should start with controlling algae in ponds. This is achieved by ensuring that at least 60% of the surface area of your pond is covered in shade. Algae need sun to propagate. Deny them direct sunlight and you will have a stronger hand in controlling algae in ponds. Of course, providing weekly routine maintenance to your pond's filtration system will also go a long way in this regard. Checking the filter, ensuring that the pumps are working properly and checking UV bulbs will not only keep algae under control, but also keep water chemistry within acceptable parameters.

Purchasing a siphon pump for your pond is another way to facilitate Koi pond maintenance. Using the siphon pump monthly to drain 10% of the water and debris which has accumulated in the bottom of the pond will lighten the load on your filtration system and keep your water chemistry in check. During this time, you can also use pond scrubbers to clean rocks, substrate surfaces and other areas that display algae outbreaks. When replenishing the water that was removed, make certain to do so only with dechlorinated water. Chlorine can be hazardous, even deadly, to your Koi.

There are also special seasonal chores associated with Koi pond maintenance. During the fall, leaves will have a tendency to fall into your pond. These should be removed as soon as possible. Otherwise you run the risk of having them decompose and contaminate your Koi's habitat.

Just before the first chill of winter hits, make certain that you have properly completed your weekly and monthly maintenance routines for that time period. Before your Koi enter their dormant/hibernation period over winter, it is imperative that water conditions in your pond be at optimum levels. Check pH, oxygen, nitrate and other chemical levels right before this period.

During winter, monitor severely low temperatures carefully. Koi are hearty fish and by nature will enter a dormant stage when the temperatures drop. Even so, if water temperatures drop below 45 degrees Fahrenheit, especially if they as such for multiple days, you may want to consider using a water heater or else relocate the Koi indoors. The latter option should be done only as a last resort.

Spring is a good time to conduct a full systems check of your filtration system. This will be around the same time that your Koi will begin to exit their dormant stage.

As the summer months roll in, especially in hotter climates, water evaporation is something hat must be kept an eye on. If water levels drop, this can lower the amount of oxygen available to your fish and also concentrate a buildup of dangerous chemical imbalances in the water. During the hotter months water replenishment may be done as often as on a weekly basis.

Keeping up with weekly, monthly and seasonal Koi pond maintenance is the best way to keep your pond and your fish at their peak. Besides, most of the maintenance routines can actually be done in such a way that they become an enjoyable way of interacting with your Koi and pond. This is very similar to the pleasure and relaxation that gardeners feel when they work on their gardens.
