From VOA Learning English, this is the Agriculture Report.
Aquaponics is a new agricultural method that combines growing vegetables and within fish. The word aquaponics is also new, it comes from aquaculture and hydroponics. Aquaculture means fish farming, and hydroponics means growing plants without soil.
Supporters of aquaponics say it is an efficient way to produce high-quality healthful food. However, it is yet unknown if the method is an environmental or financial improvement to traditional farming.
240 fish swimming in a container or tank at Cylburn Aquaponics farm in Baltimore, Maryland. Farm manager Laura Genello feeds them breakfast. "Hey, guys."
The tank water is rich with fish waste, it flows through a system that removes what is not wanted, the water then flows into vegetable crops nearby.
The floating farm grows about five to ten kilograms of produce a week. Ms Genello expects to raise about 250 kilograms of fish a year.
Environmentalist like aquaponics because fishing is threatening the exists of many wild species. At least half of the world's food fish are raised in farms, waste from all those fish causes pollution.
Dave Love is a researcher at Johns Hopkins University.
"There are fewer and fewer fish in the ocean and more and more fish will be raised on farms. The trick is, how do we do that responsibly, sustainably and in ways that make fish farmers money?"
Ellen Perlman is an aquaponics farmer also near Baltimore. She is growing lettuces and other vegetables she says are hard to find in winter.
"They grow well in greenhouses in the winter, and where also you gonna get a fresh red romaine, and this is grown locally in a greenhouse in the middle of the winter. "
However, the fish tanks need to be heated when the temperatures fall, that costs money. It is one reason Ms Perlman has not made a profit yet.
Back at Cylburn, Laura Genell notes that aquaponics still move. She says parts of the system still need improvement.

参考译文
这里是美国之音慢速英语农业报道。
养耕共生是一种将种植蔬菜和养育相结合的新农业方法。Aquaponics这个词也很新，来自水产业和水耕栽培。水产业意味着养鱼业，水耕栽培意味着无土种植。
养耕共生的支持者说这是产出高质量健康食物的有效办法，然而，尚不清楚这种方法是否环保或能给传统农业带来经济改善。
240条鱼在马里兰州巴尔的摩Cylburn养耕共生农场里的水箱里游泳，农场经理Laura Genello在给鱼喂食，“嗨，伙计们！”
水箱里的水富含鱼的粪便，通过一个系统流出不需要的东西，这些水然后流到附近的蔬菜作物中。
这个水上农场每周产出5到10公斤的农产品，Genello希望每年养殖250公斤鱼。
环保主义者喜欢养耕共生，因为养鱼威胁到很多野生物种的生存。全世界至少一半的食用鱼是在农场养殖的，这些鱼产生的粪便导致了污染。
Dave Love是美国约翰霍普金斯大学研究员。
“海洋中的鱼越来越少，将有越来越多的鱼在农场养殖。关键是，怎样才能负责、可持续地养殖并让养鱼农场主赚钱？”
Ellen Perlman也是巴尔的摩附近一家养耕共生的农场主，她种植冬天难以获得的莴笋和其他蔬菜。
“这些蔬菜冬天在温室里生长很好，同时还能得到新鲜的红莴笋，这些都是在严冬季节在温室里长出的。”
然而，这些鱼箱需要在气温下降时加温，这就要花钱。这就是Perlman目前尚未赚钱的原因。
在Cylburn养殖场，Laura Genell指出养耕共生仍在发展，她说部分系统需要改善。
