摘要
本实验首次用移植的方法在虾池内栽培大叶藻。结果表明,大叶藻可以净化虾池水质,改善虾池底质条件,丰富了饵料生物,促进了对虾的生长,提高了产量,每亩虾池的产量提高26.6％,纯利润提高190.5％。文章讨论了提高产量的原因。
There are no other economic algae that are able to live in shrimp ponds during summer time. Eelgrasses are easy to survive when transplanted to shrimp ponds and grow normally when the temperature of seawater is over 27℃. They discharge oxygen during the process of photosynthesis and purify the water quality of 'the ponds. Which is very important to the growth of Penaeus chinensis O'sbeck in culture ponds.The eelgrasses are different from other algae by having 'well-developed anchoring systems, rhizomes and roots to anchor themselves on substratum to form algaeforests in shrimp ponds. The shrimps are able to swim and graze freely in the algae-forests and get rest under forests at noon, which is an essential environmental condition for shrimps to grow in culture ponds. The quality of shrimps grown in eelgrasses ponds, is superior than that of the control. The products and benefits of shrimps can be raised to 26.6% and 190.5 % respectively.
