螃蟹可以放在冰箱保存吗？
01
虽然说鲜活的螃蟹可以直接放在冰箱的冷冻室给冷冻起来，但是这种做法感觉太粗暴了，而且螃蟹是一种水产品，我们在吃的时候最主要的就是为了吃海鲜的鲜味，如果放进冷冻室之后再烹饪的话那么口感就会大大降低，而且还会使肉质发柴，并且可能更认出来的螃蟹腥味会更重一些，所以说这样就反而失去了海鲜的鲜味，大家最好不要这样做。
02
但是可以放在冷藏室。选活力旺盛的螃蟹， 把螃蟹的脚和钳子捆起来，以减少螃蟹体力消耗，然后放在冰箱的冷藏室，盖上湿毛巾保存即可。每天吃的时候先挑选活力不足的，活力足的螃蟹可继续保存。

螃蟹保存方法
01
放盒子或盆子里定时喷水
大闸蟹的生命力很强，室温只要在15~25℃之间，就玩全可以室内存放，将大闸蟹用较宽敞的盒子或盆子放好，注意定时给它们喷洒一些水，保证它们环境的湿度，这种可以保存存活3~5天。

02
放浴缸中加水活养
如果购买的大闸蟹太多，也可直接放在浴缸中活养，浴缸四面光滑，可以保证大闸蟹不会越狱逃跑，在浴缸内放适量的水（差不过1~3cm厚），保证了大闸蟹的湿度，再投放一些小鱼、泥鳅、活虾等作为其食物，能养5~10天，随时都能抓上来吃。
tips：室温活养的大闸蟹千万不能提前刷洗，刷洗对大闸蟹有很大的伤害，会导致大量死亡。
03
塑料桶/盆加水活养
准备一个30-50公分高的塑料桶/盆，塑料桶/盆内壁光滑不易逃跑。把大闸蟹放入其中，不要层叠;然后加水至大闸蟹身体的一半高便于保湿，切忌把大闸蟹全部埋住，如果水太深螃蟹会因为缺氧窒息而死。桶/盆不要加盖，每天检查大闸蟹，把活力不足大闸蟹及时吃掉，采用这种方法保存大闸蟹，气温不高的时候大闸蟹保存可超过5天。
04
注意：不管哪种方式，建议最好能把螃蟹的脚捆起来,这样能减少螃蟹的体力消耗，螃蟹也没那么容易把自己累死。还有，如果大闸蟹太瘦或想储养一下,可以给大闸蟹喂些芝麻或打碎的鸡蛋并加些黄酒,可以催肥。
大闸蟹活养需要水分，但不能泡在水中。大闸蟹在家里活养需要一定的水分保证环境的湿度和降低温度，但大闸蟹不能泡在水中，尤其是深水，大闸蟹需要进行呼吸，泡在水中时间长了反而会窒息而亡的。

如果是活的螃蟹，首先要用皮筋等绳子捆扎好，防止螃蟹到处爬，然后把螃蟹放进一个通气的容器里，比如一个盒子里，再放入冰箱冷藏室即可。
