For several years Tunisia has opted to breed freshwater fish in reservoirs and artificial lakes, created for irrigation, as a strategy of providing high quality aquatic protein to the interior regions and providing work opportunities for local communities. The aim of this study was to summarize the main results accumulated by the last 20 year efforts made by the members of the National Institute for Marine Science and Technology (INSTM)-Aquaculture Laboratory to develop thicklip (Chelon labrosus) and flathead (Mugil cephalus) grey mullets fry production from captive broodstocks intended for stocking inland reservoirs (artificial lakes) and grow-out purposes Administration of human chorionic gonadotropin (hCG) at a priming dose of 10.000 IU kg⁻¹ female bw, followed by 10.000 IU hCG and (100 or 200 μg kg⁻¹ female bw of thicklip or flathead grey mullet respectively) as resolving dose resulted at the highest egg production for both species. Mean fecundity was 494.655 eggs kg^-1 bw for thicklip grey mullet and 418.945 eggs kg^-1 bw for flathead grey mullet. Fertilization rate of eggs produced was high (mean rate 83 % and 63 % for thicklip and flathead grey mullet respectively) and larvae hatched from those eggs at high rates (77 % and 88 %, respectively). The green method was more efficient than clear method to produce thicklip and flathead grey mullet fry, (i.e larvae had higher growth rate and better survival rates). The results of this study demonstrate the possibility to control reproduction and produce grey mullet fry in captivity. However, further research is needed to optimize the production protocol of eggs and fry of both grey mullet species.

突尼斯多年来一直选择在为灌溉而建的水库和人工湖中繁殖淡水鱼，这是向内陆地区提供高质量水生蛋白质并为当地社区提供工作机会的战略。这项研究的目的是总结国家海洋科学技术研究院（INSTM）-水产养殖实验室成员在过去20年中为开发厚唇（Chelon labrosus）和扁平头（Mugil cephalus）所做的努力所积累的主要结果。鲻鱼鱼苗从圈养亲鱼生产用于放养内陆水库（人工湖）和生长出目的人绒毛膜促性腺激素的管理（HCG）以10.000公斤IU激发剂量^-1雌性体重，随后10.000 IU的hCG和（100或200μg公斤分辨剂量分别为^-1雌性厚唇或扁平头乌鱼（bw），这两个物种的卵产量最高。厚lip鱼的平均产卵量为494.655卵kg ^-1体重，418.945卵kg ^-1bw为扁平头乌鱼。所产卵的受精率很高（厚唇and鱼和扁头gray鱼的平均率分别为83％和63％）和从这些卵中孵出的幼虫的比率很高（分别为77％和88％）。绿色方法比透明方法更有效地生产厚唇和扁平头灰head鱼苗（即，幼虫具有较高的生长率和较好的存活率）。这项研究的结果证明了在人工饲养下控制繁殖和生产gray鱼的可能性。然而，需要进一步研究来优化两种both鱼品种的卵和鱼苗的生产方案。
