Females typically lay 300 eggs at a time The adults typically die after breeding, but with the larger females laying 300 eggs in a clutch, they are survived by a lot of young. In a stable stickleback population, only two of those young must survive to maturity.

Where do sticklebacks lay eggs?
In the spring, the male develops a bright red throat and belly and performs a courtship dance to attract a mate. He builds a sheltered nest out of vegetation, under which the female will lay up to 400 eggs. The male then defends the nest from other fish until the young hatch up to four weeks later.
How do stickleback fish reproduce?
After building a nest of plant materials glued together by threadlike, mucous secretions from his kidneys, the male coaxes and drives a female into the nest to lay her eggs. He then follows her into the nest to fertilize the eggs. More than one female may be chosen, and each female may lay up to 200 eggs.
How long do sticklebacks live for?
Life-span: about three years. Food: mainly small water invertebrates; also fish eggs and young fish.
Do sticklebacks eat their young?
Outside the breeding season, sticklebacks may be found in loose shoals. 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 stickleback eggs take to hatch?
Each female lays her eggs in the nest and the male fertilises them. He then guards the eggs, fighting off possible predators, until they hatch, which may take anything from one week to a month.
What are the stickleback predators?
As the threespine stickleback is small, abundant, and a slow swimmer, it serves as a suitable prey for a wide variety of species. Natural predators include fish in the families Percidae, Esocidae, and Salmonidae, as well as avian piscivores such as loons, herons, and kingfishers.
What is the habitat of a stickleback?
The present and previous studies suggest that most sticklebacks live in intertidal areas such as estuaries, salt marshes and tidal pools, and could be estuarine residents that complete their entire lives in seawater and/or brackish water environments without any freshwater life.
Can sticklebacks eat fish food?
They have also been known to take usual fish flake food but like all fish it is important to provide a diverse diet. Aquarium Care: As long as they are in clean, non polluted water, with some element of oxygenation (be that with pond weed such as Elodea Crispa or water movement from a pump) these fish will do well.
Can sticklebacks live with goldfish?
Avoid mixing native fish such as sticklebacks with more exotic types like goldfish and carp. Sticklebacks in particular are aggressive and territorial and will harass, damage and even kill bigger fish. ... Always acclimatise the fish before putting them in the pond.
Do sticklebacks eat each other?
Summary. The threespine stickleback, Gasterosteus aculeatus is a voracious cannibal of both its own eggs and those of conspecific neighbours. Females, but not males, can distinguish their progeny from those of other fish and attacked alien eggs more frequently.
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.
Do sticklebacks eat algae?
FEEDING: Sticklebacks eat mainly benthic insects but feed on a variety of food including algae, snails, and small crustaceans and worms. Males sometimes eat stickleback eggs. Because they are visual feeders, they require relatively clear water in order to see their food source.
Can sticklebacks live with minnows?
The Three-spined stickleback
Characteristics: Flexible but very aggressive during breeding season; Well suited for small ponds. Can be kept with other small fish (bitterling, minnow, roach) but only in very large ponds.
Are sticklebacks protected?
Conservation of spineless sticklebacks
Common forms of stickleback have received no conservation status. Only fish that display some degree of ecological or genetic divergence – e.g. the spineless morphotypes – are considered to be of any conservation value.
Can fish and newts live together?
Companions. While newts can be kept with some fish, they must be species that are small, non-aggressive, and adaptable to cool water. The number of fish should also be low enough to allow the newts to compete easily for food, as they are much slower to feed than most fish.
