Zebrafish facilities have employed widely different methods, e.g., water chemistry parameters, housing systems, and breeding methods without actually checking whether the employed methods were optimal for the particular zebrafish populations kept in the facility, or whether these conditions had an impact on the research studies conducted with fish of the … Because zebrafish are native to tropical conditions, they require relatively warm water but can adjust to variable temperatures between 70°F -90 °F (5, 6) with an accepted optimum temperature of 83°F (6). It is a complex process influenced by a number of factors. Protocol written by: Natasha Meyer. The fish are photoperiodic and breed at dawn. Mate choice and mating behavior depend, for example, on olfactory cues, visual stimuli, and social interactions. Keep feeding them 4-5 times a day with live food until they spawn.

For successful breeding: In the late afternoon of the day before eggs are wanted, cover the bottom of the tank with a single layer of marbles. Lewandowski V(1), Sary C(2), Casetta J(2), Seccatto Garcia AL(3), Lopes de Oliveira CA(2), Pereira Ribeiro R(2), Vargas Mendez LD(2). To breed zebrafish, the method that I employed yielded about 20 embryos per tank, and fish were only set up for breeding for less than 24 hours, meaning no accommodations had to be made for feeding or cleaning, which is convenient for smaller labs that may not have a huge starting colony or supplies to work with. found that incubation of zebrafish embryos at 32.5°C and above from 2.5 to 96 hpf causes malformations as early as 24 hpf. firstname.lastname@example.org.
