采用不同抛秧密度和不同投鱼尾数的稻田养鱼试验表明：水稻产量以每667m2抛秧密度为8000钵的最好，投鱼尾数800尾的最高。投鱼尾数至少在400尾/667m2水平以上，使鱼粪有机肥对水稻产生影响。鱼产量随尾数的增加而增加，而以每667m2投鱼尾数800尾效果最佳。经济效益以每667m2抛栽8000钵、投鱼800尾的产投比（3.21∶1）最好。投鱼比不投鱼（B1）增加产值17.37%以上。
採用不同拋秧密度和不同投魚尾數的稻田養魚試驗錶明：水稻產量以每667m2拋秧密度為8000缽的最好，投魚尾數800尾的最高。投魚尾數至少在400尾/667m2水平以上，使魚糞有機肥對水稻產生影響。魚產量隨尾數的增加而增加，而以每667m2投魚尾數800尾效果最佳。經濟效益以每667m2拋栽8000缽、投魚800尾的產投比（3.21∶1）最好。投魚比不投魚（B1）增加產值17.37%以上。

The results of experiments on different densities of riceseedling broadcasting and different norm of putting types in paddy fields show that the highest rice yield is gotten from the broadcasting density of 8 000 banches of rice seedlings, and the norm of putting 800-frys per 667m2 in the rice field. When putting norm over 400 frys per 667m2, the organic fertilizer produced by fish can have significant effect on rice yield. The fish output increases with the increasement of putting frys number. The best input-output ratio is 1∶3.21 when 8 000 bunches of seedlings and 800 frys per 667 m2 are put in the rice field. The rice yield with putting frys increases over 17% than the yield without frys putting.
