Description
To assess their stock of sergestid shrimp Lucensosergia lucens, the spawning fraction (number of females spawning per day) should be estimated. Therefore, we studied the spawning rate of mature females using shipboard spawning experiments, and described the histological characteristics of ovaries after spawning. Spawning rates ranged from approximately 40% to 80% and were negatively affected by body size of females and sea water temperature. Histological examinations showed that mature oocytes were completely released or non-ovulated oocytes were present in the spawned ovaries. Based on these characteristics, we were able to determine spawning fraction.
