Marine fish can produce high numbers of eggs which are often released into the open water column. The eggs have an average diameter of 1 millimetre (0.039 in). The eggs are generally surrounded by the extraembryonic membranes but do not develop a shell, hard or soft, around these membranes. Some fish have thick, leathery coats, especially if ...
A pregnant Southern platyfish. Pregnancy has been traditionally defined as the period of time eggs are incubated in the body after the egg-sperm union. [1] Although the term often refers to placental mammals, it has also been used in the titles of many international, peer-reviewed, scientific articles on fish.
In many cases, the eggs are dependent on the male for oxygen and nutrition so these fish can be further defined as viviparous livebearers. [citation needed] Many cichlids are mouthbrooders, with the female (or more rarely the male) incubating the eggs in the mouth. Compared with other cichlids, these species produce fewer but bigger eggs, and ...
The spawning fish select sandy or pebbly shallows and deposit their eggs primarily between sundown and midnight. Females release eggs in batches of about 30,000 eggs, though very large fish deposit an estimated as many as 156,000 eggs. Total annual egg production is 200,000–600,000 eggs per female, with larger fish producing more.
Large females can carry more eggs than small females, and between 1 million and 29 million eggs have been recorded. [3] The pelagic eggs measure 1.6–1.8 mm ( 1 ⁄ 16 – 5 ⁄ 64 in) in diameter and 2 + 1 ⁄ 2 days after fertilization, the embryonic development occurs.
On average, 300 eggs can be expected from each spawn in a mature broodstock population, although the number of eggs released will increase with the maturity and size of the fish. Spawned eggs are adhesive, negatively buoyant in freshwater and average 1.18 ± 0.05 mm in diameter.
Fish eggs and larvae are eaten by many marine organisms. [13] For example, they may be fed upon by marine invertebrates, such as copepods, arrow worms, jellyfish, amphipods, marine snails and krill. [14] [15] Because they are so abundant, marine invertebrates inflict high overall mortality rates. [16] Adult fish also prey on fish eggs and larvae.
The convict cichlid (Amatitlania nigrofasciata) is a fish species from the family Cichlidae, native to Central America, [3] also known as the zebra cichlid. [4] Convict cichlids are popular aquarium fish [3] and have also been the subject of numerous studies on fish behaviour. [5]
