.在北方亚得里亚海的潮滩上研究了海中虾类Upogebia pusilla的种群。生物统计学分析表明，性别二型，特别是在propodus大小。大小的频率分布揭示了在所有季节的大型动物的存在，招聘青少年发生在秋季。换羽间隔和换羽增量在实验室中测定，并用于生成生长曲线，与从大小频率分布计算的生长曲线进行比较。该虫的寿命在5年以上。产卵的女性发生在3月和9月之间。产卵量春季高，夏季低，并随体型增大而增加。胚胎的孵化时间为35天;在繁殖季节，一只雌性会产生大约三批卵。对于100头动物的理论种群，估计每年的总产量为994 kJ; 13.5%用于体细胞生长，31%用于雌性产卵，55.2%作为蜕皮损失。本文还讨论了乌鳢科和丽鱼科的种群结构、生长和繁殖模式以及胚胎和幼虫发育。
. Populations of the thalassinidean shrimp Upogebia pusilla were studied on tidal flats in the Northern Adriatic Sea. Biometric analysis showed a sexual dimorphism, especially in propodus size. Size frequency distributions revealed the presence of large animals during all seasons; recruitment by juveniles occurred in autumn. Moult intervals and moult increments were determined in the laboratory and used to generate growth curves which were compared with those calculated from size frequency distributions. The life span of U, pusilla is over 5 years. Ovigerous females occurred between March and September. Egg numbers were high in spring, lower in summer and increased with body size. The incubation time of embryos was 35 days; a female produces an estimated number of three egg batches during the breeding season. A total annual production of 994 kJ was estimated for a theoretical population of 100 animals; 13.5 % is spent for somatic growth, 31 % for egg production of females, and 55.2% is lost as exuviae. The population structures, growth and breeding patterns, as well as embryonic and larval development within the Upogebiidae and Callianassidae are discussed.
