Skip to 0 minutes and 15 secondsSo. They are three type of fishery on management types. One is called investment management, so section on fishing efforts including a number of both fishing gear restriction such as fishing Nets, type of fishing hooks, quantity and specification. Limiting operating time such a fishing cut-off period limiting the operation of sea areas such as no fishing areas, Limiting the number of fishermen such as disabling of foreign migrant, so the investment management is actually we restrict the fishing effort. We say, OK, how many fishing boat can go out there? OK, if we just give you a rough number, we say OK, we only allow ten, one hundred. We give an exact number how many boats OK? And what kind of fishing gear restruction?
Skip to 1 minute and 25 secondsLet's use a normal daily word is that net has a big hole. Or a big eye or a small eye. It's really... This will really affect what kind of fish you will catch If the hole is bigger and you will let a small fish go and you will keep the larger one. So it depends. It's really the restriction on the gear itself OK and also we are limiting the operating time. Let's say it's more like... Well it depends. You can do it as a season, if you watch TV a lot you will see, oh, this is a fishing stuffon this point and fishing seasons at a certain point.
Skip to 2 minutes and 8 secondsSo limit operating time and will limit the operation Sea area So that, we say OK you can only do the fishing in this area. So Well I guess it is quite straightforward, so this is more like an investment management. OK. And we can also do output management Restriction on catches. including fish species restriction. OK, uh, production limits, body size restriction, gender restriction and mixed management. If you can exist certain percentage, you must start working stuff like that. abandon management such as shark fins do not leave So output measurement is OK, I told them. What kind of boat can go?
Skip to 2 minutes and 59 secondsHow many boats can go out there is like what kind of gear you can to use and what area, what time And now we talk about upper management. What kind of fish you can get? OK. the idea itself is pretty good right? So I restrict... What kind of fish you can get but the thing is... in old time, we don't really know, right? You get a rough idea. You say OK, in this area with this kind of gear I probably get what kind of fish? This is from experience. This is from data. This is not exact solution. This is sort of like OK. We will see. If not the one I want.
Skip to 3 minutes and 39 secondswe'll just put it back, so it's no feedback. It's nothing we can do about it. It's kind of like oh OK, we just keep something then we will see what happened, right? This is not cool This is not cool at all. Think about your fish. You just like the fish and do your thing, you lay bag, one day you got caught by the net, and you are pulled all the way to a boat and somebody said, "oh this is not the right one." And what they're going to do about you? they're going to put you back. I guess you have to do it, but what, you will say, "what?!"
Skip to 4 minutes and 16 secondsI'm just like a shrug in my backyard and I just had been caught on a boat so Output management is something we did right now. It is something we do right now. But. Without a technology, this is like oh OK, we do it first. We will shoot first and see what we'll get. The third part is quota management. The total amount of fish can be distributed to the fishery personnel who decided would decide the best working time as their own discretion. Management object is divided into the ship is the management object. The fishermen are management object such as fishing quota of offshore fishery even the tradeable quota such as Australia's black scorpion fishing quota or to protect vulnerable community quotas.
Skip to 5 minutes and 6 secondsSo this is kind of say. It's not. This is not you can so everything you catch is yours. There are allowed certain amount. OK, so now the idea again, this idea is pretty good, right? We kind of say we don't want you to over fish. so we say OK, you can only sell certain part of it, right? But, I already got a fish. If you don't allow me to sell it or what I'm going to do about it, I'm not going to eat it. It will be crazy, right? What if we can know or what if we can dynamic to. Or in real time we can know how many fish we can sell? Then we can get their direct feedback.
Skip to 6 minutes and 0 secondsOur decision. that's more like OK, if I know I can only sell 10 tons this high. There's no point I get 12 tons, right? So if I got notice before I go back to port I can just say Oh 10 tons it is. Let's go back, let's head to the bar. Let's have some good time. Let's make some money, right? But in old time we don't have this information. All we have is. We'll see after you go back to port and we' ll see or so it's. But again, this is good idea, but in realistic. Well, I don't know. I'm not so sure this is a good idea, right?
Fishery Management Types
Prof. Wu will talk about current methods of management of fisheries. There are three fishery management types: investment management, output management, and quota management. He will explain in detail of management method.
