Question
You receive animal care and use committee approval to catch a fish, prop open its
operculum (gill cover), tie a string around its tail, and tow it backwards through the
water for experimental purposes. The fish is then released unharmed. This action
forces water to flow backwards over the gill filaments and in between the gill
lamellae. What effect would this backwards water flow have on respiration?
It would reduce efficiency of gas exchange between water and blood
The only effect would be due to the fish's discomfort from this treatment.
O It would improve efficiency of gas exchange between water and blood
