Hawaiian red shrimp - Halocaridina rubra (order Decapoda; family Atyidae) is an endemic species originated from Hawaii Islands. It is adapted to a specific environment of underground systems and anchialine pools. Halocaridina rubra has a great potential for aquarium shrimps breeders as well as for researchers. The aim of this work was to: (1) document the reproduction of shrimp Halocaridina rubra and (2) determine the influence of selected chronobiological factors and presence/absence of a shelter for its reproduction. The experiment was realized in the aquarium room and chronobiological laboratory at the department of Biological disciplines at the Faculty of Agriculture, University of South Bohemia in České Budějovice. The experiment took three months (i.e. from 3 rd November 2014 to 3 rd February 2015). This experiment had 4 treatments each with two repetitions: on the light with and without a shelter, in the dark with and without a shelter. Experimental shrimps were put into the aquaria in the breeding groups: 10: 16 (female: male). The frequency of mating was evaluated. Neither the light conditions (12 h (light): 12 h (dark) or permanent dark) nor the presence of shelter had impact on the reproduction of Halocaridina rubra. The reproduction of shrimp Halocaridina rubra was documented. Spermatophore transfer, eggs, four larval stages of zoea type, megalopal stage and two juvenil stages are monitored. Recommendations for breeding have been developed. Anesthesia was tested by using eugenol (clove oil) in shrimps.
