(Digestive system), Liver: Largest organ in the salmon’s body, it synthesizes and secretes the essential nutrients (amino acids i.e. The spinal cord is a skeletal structure that connects nerves from the brain to the rest of the body. Ventral: The bottom of the fish or the belly of a human. They extract oxygen from the water using gills. Brain: This organ coordinates the messages received about the environment from the sensory organs i.e. Each fin has a different purpose. This shape allows them to make their way up rapidly flowing rivers against strong current. Humans and salmon have body parts in common: Write down external and internal body parts that we have in common with salmon. The midbrain controls vision, learning and responses to stimuli. For example, the female uses the Caudal fin (also known as the tail) to dig its redd. Water is pumped in through the mouth and sent over the gills. As the water flows over the gills oxygen diffuses in to the blood and CO2 diffuses out of the blood. Sign in|Recent Site Activity|Report Abuse|Print Page|Powered By Google Sites, Key external features of the salmon include eyes, mouth, fins, lateral line,  gill cover and nostril (nares). Brain: This organ coordinates the messages received about the environment from the sensory organs i.e. Swallowing FoodMost salmon use their small teeth to aid them in capturing and swallowing prey (herring, anchovy, sand lance). ALSO, WE ARE CREATING A SALMON DISSECTION VIDEO. Hypophysiotrophic systems in the brain of the Atlantic salmon. Just like humans expel carbon dioxide when we breathe, salmon expel carbon dioxide when the water flows out through the gill vents. It is responsible for filters dead cells from the blood stream (EXPLAIN). Compare a human eye (the size of a golf ball) to the size of our brain. Share your list with the class. Salmons breathe through their gills so the gill cover (operculum) protects the gills. The anal fin provides balance. Operculum (Gill Cover): Protects the gills, similar to how a human’s rib cage protects the lungs. Ovary (in the female)The ovary produces eggs in the female. Eyes: Fish eyes can see both to the left and right at the same time, and each eye can move independently. Swim bladderWhile salmon control their upright position in the water using their paired fins, salmon maintain their buoyancy (their floating depth in the water) by controlling their gas-filled swim bladder. protects the gills. Five interesting ways in which humans and salmon are anatomically different: Then list five interesting ways that humans and salmon are anatomically different. The Life Story of Fish. UBC Press University of British Columbia. (Nervous system), Gills: Salmon breath oxygen. The hindbrain coordinates movement, muscles and balance. However, hatcheries use it by _____ to distinguish hatchery from naturally spawned salmon. • Fins: Salmon have two sets of paired fins (pelvic and pectoral) and four single fins (dorsal, caudal, anal, and adipose). It gives them flexibility. The forebrain controls smell, the midbrain vision, and learning responses to stimuli, and the hindbrain coordinates movement, muscles, and balance. (Digestive system), Pyloric Caeca: A special intestinal pouch where most of the fish’s digestion and food absorption. 2002. It passes waste along to the vent. Their ______ helps salmon control buoyancy (how they float) in the water column. (Consider how a rower maneuvers a row boat.). HeartThis two-chambered organ is the pump that moves blood around in the fish, much as in humans, for two important purposes: LiverThe liver is a large organ in salmon. (Circulatory system), Gallbladder: Stores the green bile secreted by the liver. Go straight (using your ___). (QUICK DESCRIPTION OF THE NATURE OF THE WASTE PRODUCT.). Sockeye are almost exclusively filter feeders, and have developed more-and-smaller gill rakers to efficiently filter food. The Kidney is the main excretory organ that removes waste from the body. The University of Washington Press 25-28, © 2020 South Puget Sound Salmon Enhancement Group. 231-309, Wydoski Richard S. and Whitney Richard R. 2003. Females use their caudal fin to dig their redd (nest). Draw a full-page diagram of the external anatomy of a salmon. They don’t chew their food — they swallow it whole. Kidney’s help maintain the body’s fluid and chemical balance. Compare this to other fish, such as a flounder, whose flat shape allows it to hide on a sandy or muddy bottom. The fins are the key to a fish’s life because that is what helps them move through the water. Five interesting ways in which humans and salmon are anatomically different, Labelling and Coloring for Young Learners, Students will be able to describe how salmon use their, A salmon propels itself forward using its, The food that a salmon consumes passes down its, Waste is excreted as feces and urine through the. DHA is important for brain function. 1. The blood then goes to the second chamber the atrium, which regulates the flow into the third chamber, the ventricle. In addition it secretes green bile that is used to break down fats in food. Compare the size of the salmon’s eye to the size of their brain. The brain is quite small, about the same size as their eyes. VentUrine, feces and reproductive products (eggs or milt) all exit the body via this opening in back of the anal fin. Salmon, The Illustrated Handbook for Commercial Users. Print out our salmon diagram. Membranes carry messages from the Lateral Line. These filaments have many small blood vessels. You have lungs that remove oxygen from the air. 287, Goodman et al. Color the salmon and label the exterior anatomy parts. Salmon have gills (located under the gill cover pictured here) that remove oxygen from the water. Enzymes in the stomach begin the digestive process. (Nervous system) Gills: Salmon breath oxygen. Adults in the sea are white on the bottom, so to a predator looking up from below (such as a shark or orca), a salmon will blend in with the light of the sky. Pectoral Fins: Aids in stabilization, maneuvering, and braking. The blood is then sent away from the heart to the gills where it releases carbon dioxide and becomes oxygenated. Testes (in the male)The testes produce milt (sperm and suspending fluids) which they excrete through the vent. 3. Click on the thumbnail images below for an enlarged view of the drawings. There are many tiny bones attached to the spine. 1998. Trout and Salmon of North America. (LARRY SAYS: THIS SHOULD BE “BACKBONE”. THE SPINAL CORD IS THE NERVE BUNDLE INSIDE THE VERTEBRAE, AND NOT EASILY VISIBLE.). WE NEED A GOOD QUALITY PHOTO THAT SHOWS THE GILL RAKERS AND GILL FILAMENT. Humans, when fully grown, have 206 bones. The forebrain controls smell, the midbrain vision, and learning responses to stimuli, and the hindbrain coordinates movement, muscles, and balance. Wet your hands before handling the fish (this reduces the friction of your hands across the fish’s body, preserving the slime). light in the water column. A female salmon has ______ and a male salmon has ______. The salmon brain. Does it? Scales overlap one another to form armor like plating around the fish.
