The reading and the lecture both discusses about the importance of current for the salmons. The author of the reading feels that the devastating effects of the development can be restored by taking some measures. The lecturer challenges the claims made by the author. He is of the opinion that the measures are harmful and partial solution for the salmons.
To begin with, the author argues that the damming of the river has severely affected the salmons. The article mentions that by building dams stream of the river of the river had slowed down making difficult for the smolts and adult salmons to travel. The lecturer further elaborates on the claim made by the lecturer. he claims that before building dams salmons took 6-20 days to travel and now it has been increased to 60 days. Additionally, he says this slowdown had made less smolts to reach oceans and obviously, then few adults will come back for breeding.
Secondly, the writer mentions if such condition persists there could be a complete eradication of the salmons. The lecturer elaborates more on this topic. He provides that the speed of the stream of the river is really important for the survival of the salmons as their body while travelling goes through various physiological changes to adapt to the salt water. Since, now the salmons are taking a prolonged time to reach their destination their body is adapted to salt water while they being still in fresh water.
Finally, the author posits that various artificial measures can help restoring their population like barge can be used to increase the water stream, which will make them travel at a faster rate. Moreover, in the article it is stated that by decreasing the water level during salmons breeding period can make the water current increase and will help in restoring their population. In contrast the lecturer position is that above mentioned methods are not successful. He notes that barge has actually involved in killing salmons rather than improving the situation and increasing the water stream in spring is a partial solution. In addition, such methods have faced criticism from the electricity producing companies.
