目前想變化一下魚的食物,所以開始餵一些無添加的燒海苔;除了火焰吃一點外,大多是沒魚吃的。

是可以放在缸中四、五個小時以上,還是一個小時內沒吃完就拿出來呢?

另外,常餵的話算是高污染源嗎?
 
海苔喔~同常丟下去就被秒殺了~無法存活那麼久....
多多少少還是會有污染只是沒比顆粒來的大
自己抓個時間吃不完就拿出來吧~~
 
了解,那我就上班前放,下班回家收好了,大約12個小時。

想說每天餵一次,中間空檔用這個補。
謝謝。
 
昨天放了12個小時,回家海苔都沒了。
想問大家是溶解、散掉的可能性高,還是魚吃光的可能性高?

謝謝。

請參考表格三
Nori( 海苔) 蛋白質290(mg/g) 磷酸鹽6.4(mg/g) 0.022(磷酸/蛋白質) 資料來源:Shimek

比起其他許多的食物 海苔含的磷酸鹽比例是非常高的

也許會覺得吃掉就會被吸收

但是下段顯示: 食物裡大部分的磷酸鹽會再被排廢出來

A study of a fish farm with rapidly growing rainbow trout in the ocean showed that 78-82% of the phosphorus feed to the fish was lost to the environment. A second aquaculture study using normal fish foods showed that 62% of the fed phosphate was released to the environment, with 35% being released as soluble phosphate available directly to algae, and 27% as phosphorus in fecal pellets (which if not removed, will break down in an aquarium releasing the phosphate again). Another study showed that 81.5% of commercial diet phosphate was released to the environment, but that with a "special" diet with low phosphate and low fish meal this could be reduced to 64% lost. A fourth study showed that growing fish fed slightly less phosphate than they need (to optimize theoretical uptake) take up and retain different phosphate sources differently. Using a purified protein diet, they observed retention of 72% of the phosphorus, 51% retention of phosphorus from added fish bone meal, and higher levels of uptake and retention for inorganic phosphate supplements (such as sodium phosphate).
