Open Question: Can you help me with this biology question?
Mission
Right around the time a barrel of oil was around $150 USD I stumbled upon an article from an "expert" saying that the solution to resolve hunger was to give more money to poor countries in order to buy more tractors and more agrochemicals! So wrong! Then a thought popped into mind: " Do something! No matter what! Anything is better than nothing! ". Mission: increasing awareness of hydroponics and aquaponics as key tools in fighting hunger around the world.

Hello everyone! How I got into hydroponics is a long story...let's just say that it involves a lot of tedious farm work as a child, unsuccessful 'dirt' gardens of my own and a near electrocution from a semi-submersible hydroponic pump. I've learned that hydroponic gardening is the only way to garden for me and I've been working at it for several years now. I've built ebb/flow, nft, Mittleider, wick and passive systems and I'm always on the lookout for the easiest and most efficient means of hydroponic gardening...If you have questions, I would be more than happy to answer them...
An aquaculture facility hatched salmon eggs and released young fish into a river leading to the ocean. The fish fed grew in the ocean, and in a few years they returned to the facility. Because the number of returning fish was low, a scientist suggested adding a chemical to the river that would ______:A.Decrease their agonistic behavior B.Enable them to imprint on the facilityC.Stimulate habituation in the fishD.Improve the search image of the solutionE.Promote optimal foraging
