Abalone Fish Research Paper

On this image, we see the external dorsal side of a preserved crayfish. As part of the largest animal phylum the Arthropoda, the body of the crayfish is segmented, with jointed appendages and exoskeleton. The paired antennae (1) are long appendages located the front of the mouth and modified for help the animal to sense touch and taste. The antennules (2) are shorter, also paired with the same function but they also help to maintain balance. The chelipeds (3) are located on the front of the thorax, and they are responsible for defence and grasping food. On the at ventral part of the thorax, we found four pairs of walking legs (4), with these legs the crayfish changes locations on the bottom of freshwater lakes, streams and also on land. They

It’s a beautiful day at the beach, the sun is shining down on you as you float and drift on top of the waves. As you lay there without a care in the world, you are suddenly interrupted by a massive swarm of jellyfish; also known as a bloom. Not only does this send you into sudden terror, it also causes a much bigger threat to the ecosystem below you. The excessive growth of jellyfish swarm drastically lowers the population of fish eggs in the ecosystem. Because of this, fishermen lose millions of dollars. People in local communities are figuring out ways to solve this mass production.

It was about 10 feet long and weighed about 1000 pounds, making it smaller yet heavier than its previous ancestor the Ambulocetus. Similar to its previous ancestor the Rodhocetus was able to drag its body along the ground for short periods of time, however it mainly resided in water. Its nose had evolved to a snout which aided in the hunting of squids and fish, the primary sources of energy in its

They are known to be voracious predators with a varied diet, essentially eating any type of animal that they encounter.

Invasive species have caused losses in biodiversity and shifts in ecosystem function (Lovell et al. 2006). Under the Executive Order 13112, species are considered invasive if they are “an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health.” Aquatic invasive species have been intentionally and unintentionally introduced to other parts of the world through the transportation and release of ballast water, pet trade and aquaculture (Keller et al. 2011, Rahel and Olden 2008). Examples of aquatic invaders throughout the world include the Topmouth Gudgeon (Pseudorasbora parva) in the United Kingdom and the Eastern Gambusia (Gambusia holbrooki) in Australia. The Topmouth

Now here comes the best part...how we look! We have a narrow head and a sharp beak with a brown face. Our carapace is amber colored and has spots of red black, yellow, and brown. Our plaston is mostly amber colored. We have dark flippers. Wow! I’ve talked so much about us that we’ve made it to the jellies already.

Pterophyllum scalare, also known as freshwater angelfish, are a species of cichlid that many aquarists enjoy. Typically, these fish need very specific water conditions in order to ensure survival and are therefore not recommended for beginners. Along with that, breeding angelfish is difficult as well.

One of the markers that separate this fish from others is that it prefers turbulent waters. This can be simulated when you have a credible tank that is well worked to give the right effects. Also, due to the fact that this fish does not easily blend with those that are of the same specie; it is ideal to keep a single fish

The white abalone is an invertebrate in the phylum Mollusca and the class Gastropoda. It is a member of the family Haliotidae and its scientific name is Haliotis sorenseni ("White Abalone - Haliotis sorenseni"). Abalone are large sea snails prized for their beautiful iridescent shells and have been sought out as food and jewelry since pre-colonial times. Though abalone have existed since the Precambrian era, the earliest harvesters of abalone were Native Americans who lived along the intertidal zone in California. Shell pieces found in Indian middens, or old waste piles, along the coast of California show that it was a common food item for hundreds of years. However, the Natives likely had a minimal impact on the population of abalone. In the

I stared down at the small yellow bag in my hand, the chatter and laughter of the students behind me began to fade out of my mind as my brain began to focus only on what I was about to do. Just the thought of biting into one of those small, delectable bright red fish made my mouth overflow with saliva. But I had to control myself. I had to savor this moment. Wiping a small amount of drool off my lips, I began to feel the tiny package. It was smooth, yet the edges were rough and serrated. The soft crinkling noise was music to my ears and I almost wanted to just keep feeling it and feeling it forever. I stopped myself. I shook the bag and could hear the small “plunk, plunk” of the fish jumping around in the bag. My mind and body itched to open

The Barramundi has many other names they can be identified by such as, Cock Up, Giant Pearch, Palmer and Asian Bass. The Barramundi will just about eat anything that lives in or around water including insects, spiders,

Adaptable to a variety of conditions, they do not wander around the aquarium. A basic diet for a red rock anemone is meaty foods like mussels, or chopped fish meat and high quality frozen foods.

There are many different species of oysters. Some of these include but are not limited to: Pacific Oysters, Kumamoto Oysters, Atlantic Oysters, European Flats, and Olympia Oysters. Pacific Oysters (Crassostrea gigas) are small and sweet. These oysters are the world’s most cultivated oysters. They have more of a sharply pointed shell than the Atlantics or European Flats. Today’s Pacific Oysters are generally named after where they are harvested. Kumamoto Oysters (Crassostrea sikamea) have been described as small, sweet, and almost nutty. They are characterized by their deep bowl like shell. Kumamoto Oysters spawn later in the season and in warmer

Reproduction and life history: This species becomes sexually mature at the age from 4-6 years, and they spawn throughout the year with a peak period. The sexes of this abalone are separate. The gonads of the females are green and those of the male, yellowish. During spawning, abalone broodstock broadcast their eggs and sperm into the ocean. Males eject sperm and females eject eggs. Fecundity as measured in the number of gametes produced is directly related to female size; a large female may have over 12 million ripe oocytes whereas smaller/younger females will produce less number of eggs.

There are at least six different families in the suborder Gobioidei with close to three hundred genera and over 2,000 species described to date. Most are tropical marine fish, live on the bottom and are very small (one of the world's smallest fish, Trimmatom nanus, is from the family Gobiidae, although the smallest described species in from the family Schindleriidae). Gobies are personable and interesting to watch, especially those species that live in symbiotic relationships with invertebrates. Most are territorial, although keeping pairs or small groupings in an aquarium are appropriate for some species. Generally they are elongate with blunt heads and high-set eyes-somewhat blenny-like. Gobies can readily be differentiated from blennies, however, by their dorsal fin-many gobies have two, blennies only have one. Also gobies have pelvic fins that are fused to create a sort of suction cup apparatus. One note of caution when choosing a goby, beware that there are many fish sold as gobies that are not gobies at all. Most notably, the dragonets are often sold under the common
