Fish

mesh sizes used in fishing nets have decreased, allowing smaller and smaller fish to be caught. Many of these are too small to be used as food, so they are crushed to be made into either animal food or fertiliser. Fishing using nets is indiscriminate. Any fish which get in the way of the net will be caught in it if they are too big to get through the mesh. For every one tonne of prawns caught, three tonnes of other fish are killed and thrown away. 20,000 porpoises die each year in the nets of…

how the old man loves to fish. He does not want to think of baseball, but he wants to fish. However, he goes out to fish another day. His line went into to the water a mile deep. The sun is very hot, and the old man feels the sun on its neck and feels sweat trickling down his back. He drifts off to sleep after a while, and he is suddenly awoken. He feels a fish on his line which makes him happy. The marlin that he caught is gently pulling the boat. The old man and the fish are tousling. After…

making it harder for aquatic life to survive. This means, colder waters can hold more dissolved oxygen than warmer waters. But fish thrive in different temperatures. While some start to reproduce in the colder waters other start to in warmer waters. Warmer waters make the fish body “soft”, making them more susceptible to injuries and leads to more bacteria growth. Many bait fish can only thrive and live in much cooler temperatures,…

species of fish selected in this experiment was Nemipterus spp (ikan kerisi). Nemipterus spp or Threadfin Bream is major used in the production of surimi as it is known to exhibit good gel-forming ability (Park, 2014). Table 1 above shows the raw data of the fish. The weight of fresh fish is 12.000 kg but after deboning the weight of minced fish meat process was only left 4.970 kg. At the end of the experiment, after all the washing and pressing process, the weight of the minced fish meat…

The Inner Fish Final Assignment Sierra Dashner Biology I Ms. Burchette December 12, 2015 PART 1: Discussion Questions Chapter 1- Finding your Inner Fish The author chose to use 375 million year old rocks because anything older than that would be considered fish, or fish like. However, rocks 365 million years of age would be considered dissimilar to fish. Therefore, the author chose a median of the two in the hope that the “missing link” between fish and land animal would be found.…

Every time I go to visit my grandparents in Florida we go fishing. We take their little boat out onto the salty sea and sit for a while. One of my best memories was when it was getting late and we were going to start heading home. But I hadn’t caught a fish yet, so I asked “Papa just one more minute”, he laughed and gave me that one more minute. Almost in an instant my bouy went underwater and I reeled in a giant silverfish. I have never seen him so proud. This day will forever stick in my head…

Sound is a means of communication by animals. Many fishes are capable of producing sounds with the help of specialized structures. Fish have evolved the largest diversity of sound-producing mechanisms among vertebrates, and sounds are emitted in numerous contexts: e.g. disturbance situations, during courtship, competitive feeding and territorial encounters. Sounds are also produced unintentionally including those made as a by-product of feeding or swimming. The majority of sounds produced by…

examples of domestic kind. All fish share 2 properties one being their habitat, and second being they have backbones.Which is also known as vertebrates. Fish are cold blooded,water-dwelling, vertebrates. The combo of gills, fins, and factor of living in water differentiates them from other creatures. Researchers believe that there are more than 24,000 types of fish. Researchers have grouped about 22,000 breeds of these cold blooded vertebrates. I will be discussing 5 types of fish out of tons.…

can affect the LDH levels in a species could be where the animals live. Lizard-fish, which had the highest mean LDH activity, tend to live in shallow and deep waters all around. They like to burry themselves in sand or mud on the bottom and not move until prey comes along. My group’s hypothesis was incorrect, croaker fish did not have the highest LDH activity. Lizard-fish and croaker’s have similar habitats, but lizard-fish are more commonly found in deep water which has less oxygen available. A…
