Integrated Practice
Purpose
To wave our project into Taiwanese society, the most important thing is to contact potential consumers. Our product is designed and modified in laboratory and adjusted to maximize its best performance. However, we needed the advice from the potential consumers to meet the real-world demands. Thus, in the second part of dialogue, we went to visit an aquaculture farmer. Our ideal interviewee was an aquaculture farmer of Tainan. Fortunately, we contacted Mr. Tsai and have two interviews with him.
Dialogue
Overview
This September 15, we visit the ''Tainan-Tsai'' milk fish restaurant. There were six team members attended and Mr.Tsai treated us a table of dishes in his restaurant. We introduced our project to Mr. Tsai and his friend Mr. Lin, a doctor of aquaculture. Since Mr.Lin have worked as advisor of aquaculture companies, he was quite understanding of our project and he proposed we focus on some part to get our design more fit to the market. Mr. Tsai also told us how they put these theories into practice.
Feedbacks & Integration
They gave us useful advice below
- After our introduction,they told us that our device suits in fresh-water
- Fresh-water fishes are easier to keep and are also more profitable.Further more, fresh-water is more stable than sea water.
- The best environment for aquaculture is an aquaculture farm near to the sea.Because we could drain water from the sea without burying kilometers-long pipeline.
- Aquaculture farmers are searching for a convenient way to detect water quality and it's very important for administration.The difficulty of conventional device is hard to wash,no matter using the solar energy plate to send the data or the detecting device.So if our device could upgrade to clean-up by itself or design to ‘’ walk back ’’ after screen the water quality, it would help a lot.
These advices were brilliant ! Also,they recommended us to find a farm to the our efficiency.We put our little boat in the lake of National Cheng-Kung University now, but if we want to sale our product to the market,definitely we have to test it in the real aquaculture farm.
Aquaculture farm interview
Aquaculture farmer Mr.Tsai
The second part of interview,we went to the aquaculture farm of Mr. Tsai. We needed to know the aquaculture environment where our device would be put in.We rode to the remote part of Tainan,where we could see farm everywhere. The farm was for hatching the fry to certain sizes and sell to another farmers.To have good source of water, Mr.Tsai buried pipelines to sea,filtered water and kept it in the reservoir.
Mr. Tsai’s farm could be divided to two parts:The first one was “Greenhouse aquaculture ”.Mr. Tsai built aquaculture farm himself,which was inside the door and used the idea of greenhouse."Greenhouse aquaculture"was the latest technique that it was not that popular in Taiwan.The farm would be cool in summer and warm in winter. The second part was the water reservoir.It was the out-door device which kept a lot of water and a motor kept pumping oxigen into the water.
Feedbacks & Integration
What we saw
- The employee showed us his daily routine: Feeding the fishes
- The aquaculture farm have to test the water quality every week: the government department will set up a stand, and the aquaculture farmer need to put their water in the tube and send to the stand,testing for several index,including pH value, nitrate,oxigen concentraction and temperature AND OUR DEVICE CAN TEST THREE OF THEM( pH value, nitrate and temperature)
- They can also test their nitrate concentration by themselves to supervise---they use a tiny tube and drop water into it and observe the color change of tube.But they seldom use it.
- The experienced employee can tell if the water quality is good or not by just using their eyes.They observe the color of water and the activity of fishes to judge.
All in all,our device is useful in some way, but still has space to improve. We can test the water quality and put that data online, it may be easy for the government to supervise and The aquaculture farmer won’t need to go so far.,but we still have to consider a lot of things.
Public engagement
Questionnaire
Besides the dialogue with aquaculture farmer, we did the public engagement to understand the thought of consumer. We designed a questionnaire which target on people’s habit of buying seafood.We delivered this questionnaire person by person and through the way of street interview instead of giving the questionnaire form to write.In the end of interview,we also introduced our project to them.
According to the questionnaires, we want to know whether the consumer's purchase intention will be enhanced by water quality data provided from aquaculture industry. Accordingly, we use sign test to test it.
- H0: Less than or equal to 50% people’s purchase intention will be enhanced by water quality data provided from aquaculture industry.
- H1: more than50% people’s purchase intention will be enhanced by water quality data provided from aquaculture industry.
- N=37,α=0.01
- T=33
- p-value= 0.0000005 0.01
Feedbacks & Integration
We reject null hypothesis and conclude that the consumer's purchase intention will be enhanced by water quality data provided from aquaculture industry at a significant level = 0.01.
Thus, our device is useful to keep providing water quality data of aquaculture industry.If we put this data online, the consumers can check the water quality of food they buy, and enhance their purchase intention.In this perspective,our design of detecting nitrates concentration and put this online seems to be a very good part that closely relates to our daily life.
