The normal weight of M. salmoides is one kilogram; however, certain largemouth basses have gotten weights of over ten kilograms. Males usually do not surpass 40 cm, while females can reach up to 56 cm in length. The largemouth bass has a large, slightly sloping mouth. Its body is slender to robust, slightly compressed laterally, and oval in cross section. The corner of the mouth extends past the eye, hence its common name. (Bailey, et al., 2004; Boschung, et al., 2004) Immature Micropterus salmoides feed on zooplankton and marine insects. As they grow their diet shifts to crayfish

and other fish species. Sunfish are the food of choice for most adult largemouth bass. (Olsen and Young, 2003) Largemouth bass females reach sexual maturity at four to five months of age, and males reach sexual maturity at three to four months of age. (Becker, 1983; Dewoody, et al., 2000) The largemouth bass sister species is the smallmouth bass and they all are a part of the black basses. (Hodge, Johnson, and Magee, 2001.) In 1802, Bernard Germain de Lacépède discovered that a smallmouth’s jaw does not extend backward to a point posterior to the eye, whereas the largemouth’s does. He gave it the scientific name Labrus salmoides. Finally in 1884, Forbes described the fish as belonging to Micropterus salmoides, which is currently the valid scientific name. (Brewer and Orth, 2014) Ecology The longest known lifespan of a wild largemouth bass was 23 years. The expected lifespan in the wild, though, is around 15 years. In captivity the longest lifespan recorded was 11 years. (Boschung, et al., 2004) They desire shallow water that is usually no deeper than 2.5 to 3 meters, but they sometimes live in deeper regions. Abundant vegetation is important because it allows bass to hide from their prey and provides protection against predators. Their environment is also made up of regions of clear waters where the bass' vision can be used to detect prey. The range size is 0 to 3 meters. (Hannon, 1996; Iguchi and Matsuura, 2004) The largemouth bass is dioeciously, meaning they have separate sexes. Micropterus salmoides breeds in the spring. This time is determined by the temperature of the water, which usually ends up being around 60 degrees Fahrenheit. Females lay their eggs in the nests of males, and males then watch the eggs until they hatch. On average there are about 3,000 fry per nest, but as many as 6,000 have been observed (Becker, 1983). Behavior Female largemouth bass do not invest anything more than their gametes to their offspring.
Males begin their investment by making nests as well as protecting these nests from invaders. Once the eggs hatch, males remain with their young and defend them against all predators. This continues usually for about a month. (Becker, 1983; Cooke, et al., 2001) In the morning, largemouth bass tend to be very mobile and remain in deep waters. During the afternoon, largemouth bass are mostly sedentary and are usually found near a larger structure in deep water. As the sun goes down largemouth bass become very mobile and move into shallow water. They remain lively throughout the night with a minor decline in movement. Movement of bass usually correlates to movement of prey species. The home ranges of largemouth bass are relatively small and overlap with each other. Despite this, there is very little agonistic behavior between individuals and most interaction occurs during spawning. (Demers and McKinley, 1996; Sammons and Maceina, 2005) Largemouth bass mating system is polyandrous, meaning the female mates with several males during one breeding season. During the breeding season, each male makes and builds a nest in shallow water. Nests are usually very basic in design. Once the nest is created a female swims near, and following an act of courtship, she lay her eggs in the nest. (Becker, 1983; Dewoody, et al.,

The humuhumu are a very independent and aggressive fish therefore they breed externally,but still heterosexualy.. Once they reach the age of maturity, the female will lay her eggs in the wedges of a coral which will then be fertilized by a male soon after. Then once they are fertilized the female will come back and guard the ...
The main idea of this story Fish Cheeks was understanding and appreciation and having pride in one own unique culture. Tan mother invites the minsters family who happens to be her crush at the time who is Robert the minister’s son. Tan felt despaired during the entire evening, feeling ashamed of her family and non- American ways at dinner. At the end of the evening Tan’s mother tells her that she understands that she wants to like all the other American girls and handed a gift. Tan’s mother points out to her that she must not be ashamed of her difference, however, embrace these differences that she has found shame in. Overall the main idea was the differences that we are often ashamed of are the differences we should take pride in, because
It is believed that these darkly colored baits encourage a bass to make a clean strike that helps to easily set your hook in the fish. So the next time you are out fishing in a clear lake or stream, consider using a dark bait or lure if you are seeking to catch bass.
Its size averages 6 pounds or 2.7 kilograms in weight and 18 inches or 45 centimetres in length. The Pacific Sea basses, on the other hand, are giant fishes with bulky characteristics that reach a weight of 600 pounds or 270 kilograms and a length of 7 feet or 2.1 metres.
Just as in any other sport, understanding gives rise to advantage and success. As serious fishermen, we had dedicated much thought to understanding the fish, hypothesizing their behavior. One understanding we had already gained through previous experiences was that fish readily eat the prey that is normally available. This, we concluded, was a sort of defense against fishermen and their foreign lures and was acquired through the fishes’ own previous experience of eating a lure. In applying this understanding to our fishing, we performed a routine food chain analysis to find out what our lures needed to imitate. The results were that the part of the food chain just beneath our quarry consisted mostly of small fish such as anchovies and young yellowtail, smaller than those shad and bluegill normally eaten in freshwater ponds. To compensate for this difference we would have to use lures smaller than those we were used to using. Luckily we had some.

Spring is the season of spawning and population growth. When the water temperature is high enough, usually around or above 60°, the male bass will move closer inland and scope out a spot to build a nest or bed. “The most active spawning occurs when the water for the first time reaches 65-degree mark” (The Behavior and Habits of Largemouth Bass). This pre-spawn period is the easiest time to catch a fish, and it is best to fish near structure such as wood...
The experiment measured the survival rate, the growth rate, and the size of the brine shrimp at the time harvested in various environments. To obtain these measurements, three environments were created: sea water, brackish water, and freshwater. For this experiment the scientists used 5 liter plastic buckets. Every two days, half of the water from each bucket was discarded and new water, of each respective salinity, was added into each bucket...
Not only are they a critical part of the bays ecosystem, but they serve as a primary food source for humans living near the bay. Some examples of fish from the Chesapeake Bay Program website include: Striped bass, Atlantic Croaker, Atlantic Sturgeon, and even Sandbar Sharks. Fish are at the top of the food chain in the chesapeake bay and they take a large responsibility in keep the ecosystem in check. Some fish feed on almost any living organism they can find while others search the bottom for smaller nutrients. Fish even serve as a food source for scavengers such as birds living along the
A poem without any complications can force an author to say more with much less. Although that may sound quite cliché, it rings true when one examines “The Fish” by Elizabeth Bishop. Elizabeth’s Bishop’s poem is on an exceedingly straightforward topic about the act of catching a fish. However, her ability to utilize thematic elements such as figurative language, imagery and tone allows for “The Fish” to be about something greater. These three elements weave themselves together to create a work of art that goes beyond its simple subject.
We cognized that majority of the behavior types for Tank B were much lower in comparison to Tank A. In only one behavior type Tank B surpassed exceedingly with Tank A, which was patrol. For nest prep the minnows performed nest prep an average of 6 times in Tank A, whilst in Tank B the minnows only performed an average of 3. In Tank A, hover had an average of 12 hovers per 5 minutes, but hovering only consisted of 8 times in Tank B. Spawn was accepted as a very rare occurrence, since none of the minnows in any tank performed spawning. In the class average Tanks A had a mean spawn of 1 and Tank B had none. For our group, number of chasing performed by male minnows in Tank A edged Tank B by a quarter. The class data was very similar in which tank produced the most behaviors per mating behavior
2013) requiring it to be an opportunistic fish when searching for prey (Stagoni et al. 2013). They feed primarily on fish, crustaceans and cephalopods (Stagoni et al. 2013). The strategy used for the Lophius budegassa to get their food by waiting patiently on the seafloor for the prey to swim close enough to them and using their first dorsal fin ray as a lure to attract the prey to a dangerously close distance and within seconds the Lophius budegassa sucks in its prey with their large mouths (Institute of Marine Research). In a research study performed to observe the feeding habits of Lophius budegassa in the Adriatic sea and north-eastern Mediterranean seas, a total of 59 species were found in a typical stomach contents of 283 Lophius budegassa that were observed (Stagoni et al. 2013). Finding on average that there were 59 different species in the stomach contents of Lophius budegassa, can be concluded that the Lophius budegassa is an opportunistic fish and will eat whatever organism comes their way. In a few cases researches have discovered the presence of birds and sea otters in the stomach contents of Lophius budegassa as well (Institute of Marine
