試驗一比較池中(100 m2水泥池)育成與桶中(20 m2 FRP桶)育成草蝦雌種蝦的生殖力，在眼柄切除後二個月內的結果如下：每尾平均產卵次數分別為3.0與3.6次，每尾平均總產卵數分別為108.6與118.9萬粒，每尾每次平均產卵數分別為36.2與33.1萬粒，單尾最高產卵次數分別為9與10次，單尾最高產卵總數分別為403與434萬粒，單尾單次最高產卵數分別為83.2與77.7萬粒。以上結果顯示：FRP桶中育成與水泥池中育成草蝦雌種蝦具有相同的生殖力。試驗二比較桶中育成草蝦雌種蝦是否與石班魚混養的生殖力。在眼柄切除後二個月內的結果如下：每尾平均產卵次數分別為4.3與2.8次，每尾平均總產卵數分別為134與102萬粒，每尾每次平均產卵數分別為34.1與36.9萬粒，單尾最高產卵次數分別為10與5次，單尾最高產卵總數分別為434與272萬粒，單尾單次最高產卵數分別為66.9與77.7萬粒。試驗三比較桶中育成草蝦雌種蝦是否與沙蠶混養的生殖力。在眼柄切除後一個月內的結果如下：每尾平均產卵次數分別為1.8與0次，每尾平均總產卵數分別為45.4與0萬粒，每尾每次平均產卵數分別為24.7與0萬粒，單尾最高產卵次數分別為4與0次，單尾最高產卵總數分別為163與0萬粒，單尾單次最高產卵數分別為33.0與0萬粒。以上結果顯示：與石班魚或沙蠶混養的草蝦雌種蝦具有較高的生殖力。

In experiment 1, the reproductive performances of pond (100 m2 concrete pond) cultured and tank (20 m2 FRP tank) cultured female broodstock of Penaeus monodon were compared over two months period after eyestalk ablation. The results were as following: number of spawning per female was 3.0 and 3.6, total eggs per female was 1.09 and 1.19 million, eggs per spawning was 362 and 331 thousand, highest number of spawning among females was 9 and 10, highest total number of eggs produced by a single female was 4.03 and 4.35 million, highest number of eggs produced by a single spawning was 832 and 777 thousand, respectively. The above results indicate that pond cultured female broodstock of Penaeus monodon had the same reproductive performances as pond cultured ones. In experiment 2, the reproductive performances of tank cultured female broodstock of Penaeus monodon co-cultured with grouper or not were compared over two months period after eyestalk ablation. The results were as following: number of spawning per female was 4.3 and 2.8, total eggs per female was 1.34 and 1.02 million, eggs per spawning was 341 and 369 thousand, highest number of spawning among females was 10 and 5, highest total number of eggs produced by a single female was 4.34 and 2.72 million, highest number of eggs produced by a single spawning was 669 and 777 thousand, respectively. In experiment 3, the reproductive performances of tank cultured female broodstock of Penaeus monodon co-cultured with Perinereis mictodonta or not were compared over one month period after eyestalk ablation. The results were as following: number of spawning per female was 1.8 and 0, total eggs per female was 454 and 0 thousand eggs per spawning was 247 and 0 thousand, highest number of spawning among females was 4 and 0, highest total number of eggs produced by a single female was 1.63 and 0 million, highest number of eggs produced by a single spawning was 330 and 0 thousand, respectively. The above results indicate that pond cultured female broodstock of Penaeus monodon co-cultured with either grouper or Perinereis mictodonta had higher reproductive performances.
