Hi there, I'm not an engineer, but I am from the Netherlands, and I have studied at Aberdeen university (so I can tell you about Scotland experience). 
What I know, is that Delft has a darn good program. My cousin studies there too, and anything related to being technical people wanna study at Delft. It's got the best programs in that field. Dutch education is full on, and not easy, but you do learn a lot. 
From what I know, the master's in Edinburgh and Scotland/England in general is because the BSc degree are four years instead of the normal three years. Also it's a master's degree, which includes a semester of classes and a semester of writing your thesis/research. But many universities (in Europe) or now more going towards an applies master's degree, meaning two year master's. Which include a year of classes, and internship and finally your thesis. 
I loved living in Scotland, Edinburgh is one of my favourite cities and it certainly is a great place to study. The university is well known around the world, because, common, it's Edinburgh. 
I feel like KUL's is not for you, especially when you said the subject aren't really what you wanna learn/work in. Sure it's cheaper, but you shouldn't choose just because of the money. 
I'min the same predicament atm, and struggling to make a decision too. But in the end we gotta go for what feels right, do you wanna live in that country/city and does the program fit to what you wanna expand yourself in. Not sure if that helps, but I'm sure you'll figure it out. In the end there's no wrong decision, cause they're all fine universities. 
 
Good luck!
 

Hey!
I'm currently close to finishing a related bachelor's degree at Wageningen University and I can't recommend the place enough. It's been an inspiring academic environment to me and a great place to live. It's definitely one of the best universities for conservation, (marine) ecology, environmental sciences and fisheries, in Europe and worldwide. I'm considering similar MSc. degrees myself so I'll share what I think Sorry for the length...
I don't think the program MSc. Aquaculture and Marine Resource Management is mostly focused on aquaculture but it definitely is on the applied side of things (as is the whole university). It sounds to me like a good fit if you want to focus on fisheries and marine habitat restauration and conservation, although you might want to look at the marine resources and ecology track as an option instead of marine governance if you want to go in that direction.
There is a lot of freedom within all MSc. programs at Wageningen University, especially in the second year when you do your internship and thesis, both of which you could use to focus on your interest areas. You should know that, although the support system is fine, Wageningen University does give its students a lot independence and responsibility to keep up and go after opportunies, which has to suit you. I was an MSc. intro mentor last year and noticed the pace can feel quite high for incoming master's students. If you ask me, the 6 month internship is a big advantage of this degree compared to the shorter IMBRSea one. I know plenty master's students from Wageningen University who used the professional experience of their internship to land their first job.
If you're interested in going international, Wageningen has many (usually 1 semester to 1 year) exchange agreements with high quality universities all over the world, but it will usually cost you extra time to go abroad during your master's degree because it is not part of the standard program, so keep that in mind.
I'm less familiar with theIMBRSea degree but it looks very well-designed. An advantage of the IMBRSea program is probably its EU support, which could be an advantage if you know you're interested in an EU focused career. It might also be the best option if you're interested in working in Italy/Portugal(/Spain). It looks like you can keep your coursework a bit broader, which could suit you more or not.
You're right about the advantages of Wageningen University's quality and reputation though, which are mostly important if you know you want to continue in academia, and probably if you want to work in Western/Central Europe after your MSc. I'm not sure how well-known either is outside of Europe. If a career academia is your goal, it is usually also possible to write two theses instead of doing an internship in Wageningen, which can be great when you know you want to apply for a PhD position. PhD positions in the Netherlands are generally paid employee positions (which is great ofc.).

Getting uni funding for an MSc. degree is very uncommon in the Netherlands btw, because fees are not very high, almost all academic BSc. students progress to an MSc. and there is government funding for students from low-income families. If you are from a developing country or have refugee status I believe there are some options you could look into though.
