摘要

A method is described for artificially breeding neon tetras (Paracheirodon innesi) that can be adapted to domestic commercial production. From 1993 to 1994 (961 spawns), pairs of tetras were kept in acidified soft water at 25deg C (pH 5.5-6.5, adjustedwith phosphoric acid; total alkalinity, 3.2 mg/litre; total hardness, 6.0 mg/litre, as CaCO3). The water was also conditioned with humic acids (0.04%). A spawning substrate (nylon brush) was available for egg deposition. Fish reared in the laboratory had a significantly higher number of larvae (82 larvae/female) than broodstock collected from the wild or cultured abroad (28 larvae/female). The laboratory-reared population reached sexual maturity at 5-6 months of age, and broodfish pairs produced an average of 82 larvae every 2 weeks. Larvae were first fed rotifers and boiled egg yolk. Thereafter, fish were fed nauplii of brine shrimp (Artemia sp.), shaved cattle liver and formulated diets. At approximately 1 month of age, larvae obtained their adult body coloration.
