Common carp\u003Cbr>Diet: They can eat water plants, but prefer to scavenge the bottom for insects, zooplankton , crayfish, and shrimp.\u003Cbr>Other Information: This is a very destructive freshwater invasive species and can survive in polluted waters with low levels of oxygen.\u003Cbr>| 9. Smallmouth bass\u003Cbr>Diet: Carnivorous, its diet includes crayfish , shrimp, insects , snails and smaller fish like yellow perch. The young also feed on zooplankton.\u003Cbr>Other Information: This is a popular game fish sought by anglers. Smallmouth bass only thrive in cool water with higher oxygen levels and cannot tolerate polluted\u003Cbr>waters. The males guard the nest of eggs until hatching occurs.\u003Cbr>|\n| --- | --- |\n| 10. New Zealand mud snail\u003Cbr>Diet: This snail is a nocturnal grazer-scraper, feeding on plant and animal detritus or dead material. It also\u003Cbr>eats many types of algae and diatoms (see extra cards) .\u003Cbr>Other Information: This small freshwater snail breathes through a gill. They are very small so can be overlooked by anglers cleaning gear to prevent transferring invasive species.\u003Cbr>| 11. Zebra Mussels\u003Cbr>Diet: They filter about 1 liter of water every day removing detritus and phytoplankton.\u003Cbr>Other Information: Their feces is a food source for filter feeders. They outcompete and\u003Cbr>suffocate native clams and mussels. Since zebra mussels arrived in the Great Lakes the clarity of the water has increased greatly. This increased populations of smallmouth bass and yellow perch.\u003Cbr>|\n\n\n| 12. Rusty crayfish\u003Cbr>Diet: Young and adults eat algae, larvae, worms , fleasand beetles. Adults like to eat snails.\u003Cbr>Other Information: The young grow\u003Cbr>faster and they are larger and more aggressive than other similar species. The males molt or shed their skin twice a year. Eggs stay attached to the female abdomen until hatching and she cares for the hatchlings for about 2 weeks.\u003Cbr>| 13. White perch\u003Cbr>Diet: The eggs of other fish are their favourite food. They will also eat any small fish fry, shrimp, clams, and worms.\u003Cbr>Other Information: Common names can be misleading and these are really a type of bass. They are native to North America. Often considered a\u003Cbr>threat to fishing because eating fish eggs can decrease the populations of species like walleye.\u003Cbr>|\n| --- | --- |\n| 14. Sea lamprey\u003Cbr>Diet: This parasite attaches to fish with its suction cup-like mouth.\u003Cbr>Then it digs a hole through the skin with its sharp tongue and teeth. The lamprey then slowly sucks out blood so the host fish can survive for quite awhile.\u003Cbr>Other Information: Sea lampreys\u003Cbr>have destroyed the population of Lake Superior trout which was a top level predator. Biologists are trying to control the lamprey populations with chemicals and electric “zaps”.\u003Cbr>| 15. Chinook salmon Diet: Young salmon feed on diatoms, algae, plants, insects, amphipods and crustaceans like crayfish. Adults\u003Cbr>are carnivores , eating smaller fish.\u003Cbr>Other Information: Salmon are a favourite food for many humans because they have healthy fish oils. Salmon must have very clean water with high oxygen levels for spawning.\u003Cbr>|\n\n\n| 16. Walleye\u003Cbr>Diet: The young walleye eats leeches, larva and zooplankton. When grown they are carnivores and eat other fish especially yellow perch, minnows, crayfish , shrimp and leeches.\u003Cbr>Other Information: Anglers can catch these fish in deeper water in lakes. Walleyes can live up to 30 years old. It is the official fish of Saskatchewan.\u003Cbr>| 17. Deep water sculpin\u003Cbr>Diet: They eat small shrimp, crayfish, amphipods, and insects like fleas.\u003Cbr>Other Information: Because they are bottom feeders in a lake their diet has more pollutants. Sculpin are designated as a species at-risk of extinction and are protected under Canada’s Species at Risk Act. Sculpin are found in the depths of the\u003Cbr>Lake Baikal, the deepest lake on Earth at 1642 m.\u003Cbr>|\n| --- | --- |\n| 18. Round goby\u003Cbr>Diet: Gobies eat clams, snails, crayfish, fish eggs, shrimps, and larvae of insects like fleas.","cbCaih0ENoEIun1l","https://ap.wps.com/l/cbCaih0ENoEIun1l","pdf",450897,6,"English","# Species diet and feeding role\n## Common carp\n## Smallmouth bass\n## New Zealand mud snail\n## Zebra mussels\n## Rusty crayfish\n## White perch\n## Sea lamprey\n## Chinook salmon\n## Walleye\n## Deep water sculpin\n## Round goby\n## Banded mystery snail\n## Yellow perch\n## Daphnia or water fleas\n## Amphipod or fresh water shrimp\n## Invasive amphipod or fresh water shrimp\n## Fishhook water flea","[{\"question\":\"What do the cards mainly describe for each species?\",\"answer\":\"Each card provides the species’ diet and additional ecological information, such as habitat needs, behavior, and environmental impact in the Great Lakes food web.\"},{\"question\":\"Why are invasive species like zebra mussels and round gobies important in the cards?\",\"answer\":\"The cards explain how these species outcompete native organisms, affect water clarity or native populations, and can alter predator-prey relationships.\"},{\"question\":\"How do filter feeders fit into the Great Lakes food web in these cards?\",\"answer\":\"Species such as zebra mussels and certain snails are described as filtering water to remove detritus and phytoplankton, with downstream effects on other organisms that depend on water quality and available food.\"}]","Great Lakes Food Web Cards - No Insects | PDF"]
