The largemouth bass reproduces in the spring. To the largemouth basses spring time is typically when the gets to be around sixty degrees Fahrenheit. The females lay their eggs in the nest that the males have created and leave the males there to guard it. The females generally lay about 3,000 eggs per nest, but research shows that some of them have laid up to 6,000. (Becker,
The poison dart tree frog’s scientific name is Dendrobates Tinctorius and the family name is Dendrobatidae, these animals wear some of the most beautiful colors on Earth. They are amphibians who habitat freshwater and usually live 3 to 15 years. Individual habits extend from Costa Rica to Brazil,
Salmon are fish swim upstream to spawn: they are born in fresh water, migrate to the ocean, then return to fresh water to reproduce. “The salmon run” is the time when salmon have migrated from the ocean, swim to the upper reaches of rivers where they spawn on gravel beds. Salmon can make amazing journeys, sometimes they can move hundreds of miles upstream against strong currents. Most salmon species migrate during the fall (September through November). Salmon spend their early life in rivers, and then they swim out to sea where they live their adult lives.
Fish can reach marketable size of 3 kg in 12–15 months. California yellowtail, Seriola lalandi proved to be a suitable candidate for marine aquaculture. Because the juveniles of California yellowtail are not easily available from the wild, hatchery produced juveniles are produced for aquaculture projects whereas the largest operations do exist in Australia. Aquaculture initiatives have been attempted in cages and land-based systems in New Zealand supported by hatchery-produced fingerlings. Japan is the key importer and consumer of California yellowtail whereas the species is also cultured and consumed as
Main enemies of glass frogs are snakes, mammals and birds.” In the wild, Glass frogs usually live between 10-14 years. Glass frogs mate after rainy season, or during light showers. Female frogs lay between 10 and 30 eggs on the undersides of the leaves that hang above water, so the tadpoles can easily get to it. The tadpoles will hatch after two weeks and drop into the water. Some species of the frog will bury themselves in the ground, and go through metamorphosis underground, until they turn into adults.
As juveniles, loggerhead turtles reside in costal areas and migrate seasonally between summer and winter habitats (Lohmann and Lohmann 2003). In this stage, turtles spend 75% of their time at the top 5 meters of the water column and sometimes dive to depths greater than 200 meters. When they are near seamounts, oceanic banks, and ridges around oceanic islands, the turtles can spend more time at the bottom of the ocean for feeding.
The article explains the phenomena of sex change in clown fish by using an unlikely event as an example, three young clownfish survive their journey into adulthood and establish a population with an unsettled anemone. Rhodes explains that two of the three fish will become male and female, while the third remains unsexual. In the event that the one female dies, the male clownfish becomes the alpha female while the unsexual third fish will become male, a process which reorganizes the gonads of the clownfish, which usually takes about two weeks. It is also mentioned that sex change does affect the behavior of the fish, with the alpha male who will eventually become female takes on the aggressive behavior of an alpha female. The author does mention that not much is known what role the brain takes in the sex change, but that it might have something to do with the excretion of hormones form the pituitary gland.
Palumbi and Walsh et al. (2005) explain that the bigger fish are afraid of getting caught or eaten. Bigger fish don’t go out looking for as many meals as smaller fish do to their fear. Fish then realize that they need to mate with a smaller to have a better your chances are for survival. These articles I read both seem to corroborate that the bigger fish aren’t the best for mating disadvantage of being big fish.
There I was at the Republican River, GoPro on my head. It was the middle of July a hot, humid day. I felt kind of worried that what I wanted to happen wouldn 't happen wouldn 't happen. I had 6 banklines set and I stared at the east and worked to the west they were baited with large Blue Gills. I was halfway through them when I came upon my first moving line which happened to be a 5lb Blue Catfish I pulled him in then through him back.
By choosing theDasyatisAmericana as control specie, the experiment was able to control for factors such as size and the specie type. The results are intended to give insight into if color patterns act as a warning sign to the prey that the predator stingray is poisonous. Inside the aquarium, the Himantura leopardis not poisonous as a measure of protection to the other species in the fish tank.As the observer, I had no manipulation of the fish tank. There were variations that occurred during the experiment that could not be controlled as during the beginning of the observation, feeding was
