How do sticklebacks care for their offspring?
When the nest is full, the male becomes its guard and caretaker; by fanning the eggs with his pectoral fins, he aerates them until they hatch, and he aggressively defends the eggs and any young from intruders. Parental care is given by the males in all but the white stickleback (Gasterosteus species).
What features allow sticklebacks to survive in ponds?
The estuarine variety has developed the 20 -30 bony plates on the body flanks as an adaptation to the salt. This allows them freedom to swim up saltmarsh creeks at high tide, out into seawater and back to freshwater without the problem of water concentrations.
What happens to sticklebacks in winter?
Marine three-spined sticklebacks migrate out to sea in the winter, returning to freshwater rivers in the spring to spawn. Freshwater three-spined sticklebacks tend to be more sedentary, staying in the same place for their whole lives.
How do sticklebacks mate?
He uses his mouth to glue the bits of plants together. When the nest is finished, the male tries to entice as many females as he can into his nest. Each female lays her eggs in the nest and the male fertilises them.
Why are male sticklebacks territorial?
Males defend nesting territories during the summer breeding season and do so exclusively for reproductive purposes.
How big do sticklebacks grow?
Sizes. The maximum size of the best-known species, the three-spined stickleback (Gasterosteus aculeatus), is about 4 inches, but few of them are more than 3 inches long. They mature sexually at a length of about 2 inches. Most other stickleback species are roughly similar in size or somewhat smaller.
What do baby sticklebacks eat?
They eat all sorts of invertebrates, such as worms, insect larvae, small snails, crustaceans and water fleas. They even eat young fish and fish eggs - sometimes searching out those of other sticklebacks!
Are sticklebacks good for garden ponds?
If you fancy introducing fish, sticklebacks are a good choice for small ponds with their fascinating behaviour, but can effect insect and amphibian populations. ... Grass carp have an 'all you can eat' approach when it comes to planted ponds; they will happily eat any aquatic vegetation.
How do sticklebacks survive?
Stickleback fish are able to adapt their vision to new environments in less than 10,000 years, a blink of the eye in evolutionary terms, according to new research. ... The fish adapted by altering the expression of their opsin genes, which encode the light-sensitive receptors on retinal rod and cone cells.
How long do sticklebacks live for?
Life-span: about three years. Food: mainly small water invertebrates; also fish eggs and young fish.
How do you get sticklebacks?
Once abundant, location is now key if you want to catch a stickleback. In shallow, weedy and clear water, careful observation will reveal this tiny fish. Your best chance will likely be with the use of a fine mesh landing net or children's dipping net.

Feeding: Can be fed very small pieces of fresh or frozen fish. Will readily eat commercial tropical fish flakes, and zooplankton. They will eat small caprellids off of clumps of hydroid placed in their tank. Tank Cleaning: Once a month, the fish should be removed from the tank and placed into a holding bucket.

Their costliness means that they are reliable indicators of a male's quality, since only the fittest males can afford to produce them. ... Second, sticklebacks are unusual in that males care for the developing eggs and fry. A female wants to know that her mate is healthy enough to perform these duties well.
Do sticklebacks have teeth?
Stickleback pharyngeal teeth resemble oral teeth morphologically in whole-mount and in histological sections, and molecularly by gene expression patterns.
How big do sticklebacks get?
Brook sticklebacks are minnow-sized fish. They usually do not grow much bigger than 60 mm (2.4 in). The biggest ones reach about 80 mm (a little over 3 in). The brook stickleback is like many of the smaller species in Minnesota in that it lives for only 1 to 2 years, occasionally for 3 years.
