鱼虫 【求助】天渐渐转冷了，家里养的几条大红鲤鱼该如何过冬？

[郁郁枫华]

眼看着夏天在悄悄离去， 天气日渐转冷。 俺家院子里的鱼池养的九条大红鲤鱼， 不知如何过冬？

求教行家给出个主意： 要不要去买个大鱼池什么的放在室内？ 是否需要购买水泵及水循环系统等等？

谢谢！

没养过，不知道，不过这里以前有人讨论过，你可以查查。

不怕小猫下去捞鱼吃？

现在猫咪还小， 还没那么大本事， 等将来长大了， 就难说了。

Winter Care of Pond Fish

Outdoors

A portion of the pond must be a minimum of 30" deep, preferably 36"-48", to protect fish from long cold spells. But even more dangerous than cold water is the buildup of toxic gases in a pond that is completely iced over for an extended period of time. Therefore, a portion of the pond's surface should be kept open, to allow the pond to "breathe", disposing of toxic gases and adding oxygen. This may be accomplished in one of three ways:

Heater / De-Icer. We now stock several reasonably priced de-icers that are safe for use in concrete, liner or even preformed ponds. The classic version is powerful (typically 1250 watts or more) enough to keep a small pond ice-free, or to allow a "breather hole" in a larger pond, and have been tested at down to -10 o F.. They are preset to operate only when the water temperature approaches freezing to save electricity. Aquarium heaters are totally unsuitable for outdoor use; should they break due to harsh weather, live electrical wires are left lying in wet snow. In recent years, more energy efficient models of de-icers have appeared on the market. Please see Pond De-Icers for more details and our comparison guide.

Aerator. A large airstone operated by a standard aquarium air pump can also keep a small opening in the ice, at least during milder weather. Unfortunately, the precise placement of the aerator is hard to arrange and quite critical to its success: if it's placed too near the surface, it will simply freeze in place during colder weather; if it's placed too deep, it could actually chill the pond by bringing slightly warmer up from the bottom of the pond, and replacing it with the coldest water from the surface. The aerator should ideally be placed about halfway up from the deepest part of the pond and monitored frequently.

Water Pump. A water pump can also be used to provide an opening in the ice, but with the same limitations as an air pump. A submersible pump should be firmly mounted over the deepest part of the pond, far enough from the surface that it doesn't freeze solid, and far enough from the bottom that it doesn't circulate the lower layers of water. It also needs to be near enough to the surface to circulate the upper layers but not to allow pieces of ice into the intake. No filters other than possibly a coarse intake prefilter should be used (imagine cleaning a filter outdoors in February!), since any reduction in the flow rate will increase the likelihood of the pump freezing in place. Also, no fountain heads or waterfalls should be used; they create some attractive ice sculptures, but actually drain the pond in the process. Pumps should be inspected regularly; if they run dry or freeze solid, they will likely be destroyed.
Covering the pond. Covering the pond, or even a portion of it, can help protect it from extreme weather and drastically reduce the amount of electricity needed if a de-icer (heater) is used, but the cover must be raised above the surface of the pond to allow for gas exchange and an insulating layer of air. Ideally, a wooden frame would be built over the surface of the pond and covered with plywood, then insulating materials like Styrofoam, straw or even mulch. This could then be covered with a tarp or plastic sheet, to again trap in an insulating layer of air. They cover must of course be sturdy enough to withstand snow accumulation.

Feeding the Fish. The short answer to this is: Forget It, even if the fish look interested. In colder water, fishes' digestive systems are sluggish. The best option for the hobbyist is to feed easily digested foods, especially those made from wheat germ, when the pond temperature drops below 55o F.. Feeding should be stopped altogether when the pond temperature drops below 45o F.. Wheat germ foods should be again utilized in the Spring, when the water temperature is between 45o F. and 55o F., to provide an easily digested diet after the long cold winter.

如果室外温度低于18℃就要把鱼移到合适的地方了，要加水循环系统，这鱼吃得多拉的也多，看图片这鱼也就一个夏天的样子，还小哪。

谢谢小兔，CISCO，飞龙的指点。 俺现在要好好筹备筹备鱼儿过冬了。

有是有， 就是有反光， 照得不好。 瞧瞧：

好肥的靓鱼。

说说俺的经验，俺的鱼去年冬天（11月到4月）养在车房里，30G＋6条鱼，鱼缸用半寸的泡沫塑料包起来保温，加过滤。加热棒和灯用定时器控制。每天中午开3小时灯，晚上开加热，水温天冷时控制在水不结冰或少量结冰的状态。水温高过十度时，少量喂食，低于十度以下停止喂食。过滤器的作用主要是给水充氧。低温时其他生化过滤功能可能已经不起作用了。一个冬天没有换水，鱼没有损失。

谢谢Solaries的经验分享。

我的鱼儿们现在有了能遮风挡雪的小暖房，应该能安全过冬了。 稍候再上小鱼屋的片片。

[咖啡事点]

鲤鱼 冬天只要池水够深不完全冻结，及时在冰面打气眼，注意冲养，完全可以过冬，不需要额外加温，东北冬天过冬的鱼池都是这样的，冰层能有一尺多厚。

[树上想飞的鱼]

漂亮，有点园艺的感觉了，能否详细说说过冬的筹备工作，给大家留个经验

请问您是从哪里买的锦鲤？ 我也超级喜欢锦鲤。 前些日子去了 BIG AL 看到锦鲤超级贵。
不知道那里有有便宜一些的， 价格可以接受的锦鲤卖？

镜头前加偏光镜可以去除反光

說說我的辦法作大家參考：
我的池塘最深處大約4英尺，冬天把水泵停了，在水面上放一加熱器，保證水面上有一處沒結冰的，這樣有一個空氣交換的孔，然后就是放個加氧氣的在水里，一直打著不停，就行了。我的加熱器和加氧器是請人做的二和一，去sheridan nursery 問過，加熱器$200, 加氧氣大概$100 多，但原理是一樣的。

整個冬天不時查看加熱器，確保是一直在工作。我有兩天沒注意，結果加熱器電源因為雪化之后浸水跳斷，停止工作了兩天，等我讓加熱器重新工作起來，水面已經結冰了，結果今年四月池塘化開后發現有三條魚凍在冰里，心疼啊。

我院儿里的的池子是塑料的，只有1尺半深，现在的加热器只在冰层流了一个小气孔，不知冰层有多厚，也不知五条鲤鱼怎莫样了。不知咋办好。把鱼请回室内，不知有没有必要，行不行啊？为啥有人把鱼放车库里呢？有啥好处呢？

另外，室外的池子怎莫处理呢？会不会冻裂呢？请大家给个建议吧。
