What Is A Baby Fish Called

Fish life cycleLike all animals, fish need to survive and grow large enough to reproduce. Fish reaching adulthood and spawning time use a variety of strategies to ensure successful spawning. This lesson examines the factors that keep a fish alive while examining the life cycle of Great Lakes.Unit: Grades 4-8 Reading: what is the fry called Read more: March 2 belongs to which zodiac signPerformance Expectations:

Story

Many Great Lakes fish can be found in shallow water for part of their life cycle. Many species use the shallow waters of a lake or river as a breeding ground in the spring or fall. Some, such as the northern pike, prefer wetlands with aquatic vegetation. Others such as the lake whitefish prefer shallow reefs, which provide plenty of areas for food and rocky structures to protect eggs and later juveniles. The life cycle of fish varies between species. In general, however, fish progress through the following life cycle stages:

  • Eggs: Fertilized eggs develop into fish. Most eggs do not survive to maturity even under the best conditions. Threats to eggs include changes in water temperature and oxygen levels, flooding or sediment, predators, and disease.
  • Larvae: Larval fish live off the yolk sac attached to their body. When the yolk sac is completely absorbed, the fry are called fry.
  • Fry: Fry is ready to start feeding itself. Fry go through several other developmental stages, which vary by species, as they mature into adults. Juveniles are usually considered juveniles during their first few months (the first few months come to just under a year in some species).
  • Juvenile: The time it takes fish to develop from fry to reproductively mature fry varies between species. Most fish do not survive to become adults. Threats to existence include fluctuations in water temperature, changes in oxygen levels, habitat competition and predators.
  • Adult fish: When fish are fertile, they are considered adult fish. The time it takes to reach maturity varies between species and individuals. Fish with a shorter lifespan have a faster maturation time. For example, female gobies mature in about a year and live for two to three years. Lake sturgeon can live for 80-150 years, but females do not mature until they are about 25 years old.
  • Reproduction: Females drop eggs into the water (either into the water column or into the nest) and the males fertilize the eggs by releasing colostrum. Not all eggs are fertilized. Some fish lay eggs every year after reaching adulthood, others cyclically (e.g., every four years), while others lay eggs only once and then die.
