摘要
观察总结了唐鱼的几种繁殖行为,即占区行为、张鳍行为、对峙行为、撞击行为、攻击行为、求偶行为以及交配行为。同时,在控温条件下,用解剖镜和显微镜观察了不同温度条件下唐鱼的胚胎发育,将唐鱼的胚胎发育过程划分为29期。分析了水温变化对唐鱼胚胎发育速度的影响,唐鱼胚胎发育的最适温度范围为24～27℃。对唐鱼的保护提出了建议。
Reproductive behaviors of T. albonubes were observed and summaried in this paper,including range behavior, stretching fins, confronting, collision, attacking, courtship and mating. Also, We studied its embryonic development through microscope, divided and illustrated it into 29 developmental stages. The fertilized egg of T. albonubes was transparent, adhesive and spherical in Shape, measuring 0.86 - 0.89mm in diameter. Under the water temperature of 27℃（ ＋0.5℃ ）, it took 34 hours and 8 minutes to complete embryonic development. Time for incub - ation showed a negative correlation to the water temperature. The optimum incubation temperature for T. albonubes embryos was between 24℃ and 27℃. In addition, we gave some conservative suggestions of T. albonubes.
