In one sentence, describe what the following article is about: Bass are very active and swim most of the day and night. They will often start to follow you along the tank once they get to know the feeding routine. Bass do grow very quickly, so try to catch or buy a smaller one, close to 3 to 4 inches (7.6 to 10.2 cm) so you can enjoy watching it grow.  Bass enjoy small insects, algae, shrimp, and bloodworms, and they also can be taught to eat flakes or pellets. Bass will generally eat about 2/3 of their weight every day, which means you’ll need to keep an eye out on your filter to make sure it keeps working properly. You can easily catch sunfish in the wild, and there are about 30 separate species. These are also great fish if you have a smaller aquarium. They’d do well in a 55 to 75 US gal (210 to 280 L) tank. Most sunfish eat insects, small fish, and crustaceans, and they don’t grow as fast as bass. Large, adult sunfish can become territorial, so keep an eye on their behavior. If they get too aggressive, they may need to be moved into their own tank. If you love the look of tropical fish, the pumpkinseed would be a good choice for you as they’re the most similar in coloring. At the most, the pumpkinseed should only grow to be 9 inches (23 cm), which makes it a nice tank addition.  Pumpkinseed fish like to eat small insects, snails, and larvae. They’ll also eat shrimp, bloodworms, flakes, and pellets. Pumpkinseed fish can be very aggressive, so keep an eye out and remove them if they start attacking their neighbors. They eat algae, plankton, and small insects, but they will also eat flakes, shrimp, and bloodworms. At the most, add 2 minnows per 10 gallons (38 L) of water. These are fish that can withstand a lot of changes in their environment, which makes them a nice investment for your aquarium. If you’re buying these fish, they’re often called “rosy reds.” Trout need colder temperatures than most other gamefish, so they often can’t be combined with the general varieties, like bass and sunfish. Keep the temperature at 59 to 63 °F (15 to 17 °C). Trout also need a lot of strong currents, so make sure your tank is equipped to aerate the water a lot. For a 1,000 US gal (3,800 L) tank, at most you’d want to add 2 to 3 trout, so keep that in mind when choosing fish for your aquarium.  Trout like to eat leeches, bloodworms, and small insects, and they also can be taught to eat flakes and pellets. The brown trout and the rainbow trout are the ones most often kept in aquariums. Carp will grow to be up to 4 feet (48 in) and produce an excessive amount of waste. Alligator gar can exceed 6 feet (72 in), and sturgeon can also grow to 6 feet (72 in) and weigh over 200 pounds (91 kg). A lot of these fish would also eat their tank mates. When in doubt, do some research or ask someone who has an established gamefish aquarium for recommendations.
Summary: Keep bass in your aquarium for a lively, animated fish. Choose freshwater sunfish for a colorful fish that’ll thrive in a tank. Add the colorful pumpkinseed to your tank for an iridescent addition. Pick the fathead minnow for a durable addition to your tank. Select trout for your tank if you can keep the temperature cooler. Avoid buying or catching fish that will grow to be too large.

A forward contract is an agreement between a buyer and a seller to deliver a commodity on a future date for a specified price. The value of the commodity on that future date is calculated using rational assumptions about rates of exchange. Farmers use forward contracts to eliminate risk for falling grain prices.  Forward contracts are also used in transactions using foreign exchange in an effort to reduce the risk of losses due to changes in the exchange rates. A derivative is a security with a price that is based upon, or derived, from something else. Forward contracts are considered derivative financial instruments because the future value of the commodity is derived from other information about the commodity. The future value of the commodity for the forward contract is derived from the current market value, or spot price, and the risk-free rate of return. In investing, hedging means minimizing risk. In forward contracts, buyers and sellers attempt to minimize risk of losses by locking in prices for commodities in advance. Buyers lock in a price in hopes that they will end up paying less than the current market value of a commodity. Sellers hedge their risks with forward contracts in an attempt to protect themselves from falling prices.

Q: Balancing on one foot, especially while moving parts of your body at the same time, will helps you continually adjust to keep your body weight balanced. Stand with both feet together. Raise one foot a few inches off the ground. Stand like this for a few seconds with your eyes open. Then close your eyes and continue to hold the pose. Repeat on the other side. Do this set about 5 times every day. For this move, your arms will swing around like the hands of a clock while you balance on one leg. Stand on one leg and look straight ahead. Put your hands on your hips. Raise one arm up to the 12 o’clock position, then start to move your arm around to the 3, downward to the 6, and over to the 9. Repeat with the other leg and arm. Try to move as little as possible except for your arms. Breathe evenly and concentrate on keeping your body still. Your trunk is the core of your body, and practicing balance with a focus on your trunk will help you stabilize your body and improve your balance. To do trunk turns, stand with your feet just more than shoulder-width apart. Stand on a mini trampoline or other surface that is somewhat squishy or malleable. Hold a heavy item in your hands, such as an exercise ball, a weight, or something similar. Turn your body at your waist to one side and then the other about 10 times. Make the movement a smooth and deliberate motion, but don’t swing back and forth. You want your body to work for every twist of your trunk. Don’t use the momentum of the twist to propel you into another twist. This exercise requires your legs to be very strong and able to balance while you lift a weight upwards. To do this exercise, balance on your left foot and keep your left knee slightly bent. Bend forward at the hips and touch the ground with your right hand. Hold onto a 5-pound weight with that hand. Raise your right leg behind you. Move smoothly back to an upright position. Repeat with the other leg. Do up to 5 sets of this exercise a few times a week. Practice doing this movement in one clean, smooth motion. Try not to wobble around. Breathe evenly and focus on engaging your core and leg muscles to keep your movement deliberate.
A: Balance on one foot. Try the one-legged clock with arms. Do trunk turns. Do a single-leg dead lift.

Problem: Article: Using marble, granite, or any other solid surface is too hard and unyielding for a kitchen knife. This can dull your knife much more quickly. Choose a wooden cutting board instead of one made of plastic or any hard, solid material, such as glass. You should sharpen your knife annually. Honing is similar to sharpening, but it focuses more on removing nicks and recalibrating the angle of the blade. You should hone more often than you sharpen.  Some ways that you can sharpen your knife include: using an electric sharpener, sending it to a professional, or using a sharpening stone. You can find more specific instructions on how to sharpen your knife at this website: http://www.seriouseats.com/2010/04/knife-skills-how-to-sharpen-a-knife.html. While cutting, frequently rinse it off with hot water and wipe it clean to keep food from building up on the blade. This prevents the blade from dulling and working less efficiently.
Summary:
Always cut on a cutting board. Sharpen and hone your knife regularly. Keep your knife clean while you're using it.
