| 摘 要： | 分析了沿海滩地３种框围养鱼方式（即精料、种草、化肥养鱼）的能量转换效率及种草养鱼的经济效益。初步得出：在沿海滩地低投入框围养鱼中应重视对太阳能的利用；种草养鱼在３种养鱼方式中能量转换效率最高，经济效益较佳，应推广种草养鱼技术，提高资源利用率。

| Abstract: | The energy conversion efficiencies of three em-banked fish pond ecosystems ,namely,fine fodder,grass and fertilizer for fish culture,were analyzed in the seashore,and the economic efficiency of grass-fed system was anlalyzed .The results showed that attention should be paid to solar ener-gy utilization in low input's embanked fish pond ecosystem a-long the coastal areas .The encrgy conversion efficiency of thegrass- fed system was the highest among three fish culture models,and the economic efficiency was better.The technique of planting grass for fish culture shoud be popularized in or-der to raise the utilization efficiency of natural resources along the coastal area. |
