The frog in culture is faced with many problems:(1)predation by mammals,birds,reptiles and small aquatic insects;(2) cannibalism;(3) diseases;(4) inadequate food supply;(5) poor water quality;(6) sporadic egg production;(7) fluctuating temperatures;(8) poor sanitation;and(9) inadequate nutrition. In the semi-natural systems several of the above problems are magnified because the frogs cannot be easily observed to detect conditions of health,diseased frogs controlled laboratory culture systems or in commercial facilities using a building or partially protected concrete ponds,the same problems exist but are not as acute.

Although there are many edible frogs (Culley,1984) the bullfrog has dominated the production for human consumption. Despite significant knowledge of bullfrog culture,serious efforts toward scaling-up production have not been successful. A significant growth in commercial systems will be slow because of the technological complexity,and not due to the widely held myth of the slow growth rate. With adequate food and optimum environmental conditions bullfrogs grow rapidly.

    在文化裡的蛙面臨很多問題︰ (1)透過哺乳動物,鳥,爬蟲和小的水產的昆蟲的捕食; (2)同類殘食; (3)疾病; (4)不適當的食品供應; (5)貧窮的水質; (6)零星的蛋生產; (7)波動溫度; (8)貧窮的衛生; 以及(9)不適當的營養。 在半自然體系裡 一些上述問題被放大,因為蛙不能容易被觀察發現健康狀況, 或者在使用一座大樓的商業設施有病的蛙控制實驗室文化系統或者部分保護具體的池塘, 相同的問題存在但是不那麼厲害。

    雖然有很多食用的蛙(卡利,1984),但是牛蛙已經對于人消耗支配生產。 儘管牛蛙文化的重要的知識,為向上攀登生產的嚴肅的努力不成功。 因為技術上的複雜性,在商業制度方面的顯著的發展將是慢的,而不由於廣泛拿的慢的成長率的神話。 用足夠的食品和最佳環境狀況牛蛙迅速增長。
