Fisheries management requires understanding oceanographic factors such as currents, sediment transport, and seasonal productivity patterns, as demonstrated by the North Kenya Banks where the Tana River deposits 7 million tons of nutrient-rich sediments that create productive fishing grounds during the southeast monsoon, attracting tuna and other fish species.

Added:the livelihood of the people that are depending on these.
>> So this also guides us with our licensing regime.
>> Mhm.
>> Who do we need to license? What species?
>> What are the quarters looking like?
>> So it's of great use to the government making decisions. All the information we're collecting is passed on to country and the scientists are informing the fisheries management of the >> and the collection of the data is done both by the researchers from the different countries right?
>> Yes. And of course the data being analyzed by the researcher but all our instrumentation tools that we are using sensors for example are collecting in real time data that are being all provided to the countries the owners of the government you are ensuring [laughter] Norway and in that aspect it's the initute of marination how to use it. We are just in case in the future. [clears throat] Yeah.
Heat.
[laughter] Heat. Heat.
inside.
It's very important for me to know where the floor is.
You can see the shape of the of the floor how it looks but not everything is optional. There's nothing but time of course, 500 m.
range of professor we don't have a range we can do whatever you want but here we deployed those are you deployed at maximum 900 try to save them but uh we don't have to because Great. How what is the collaboration with our people the port management team here?
Yeah, we have a aent at store marina assist us in everything when we take the provision and doctors supplies and so it's very good protected nose.
was kio.
Yes, I have engaged in a lot of blue carbon.
>> Yes. [laughter] >> You know, we focused on that space.
>> We we did our M's program together. We did undergraduate together and then uh we did our M's program together. But I did master's program in something else.
You did in marine college.
>> Getting back to you. Yes.
So in here you can see on the screen essentially There's no We areing uh as I said earlier it cannot do that only by fish we cannot understand their environment their shifts in distribution their abundance without taking into account environmental parities especially indicating local parents are very strong factor >> because they reduce productivity by >> uh and then of course we have instruments that goes down to 4,000 m and we're collecting [laughter] temperature stability We're having the motivated water both in 2025 and 2026. We want the North Kenyan banks.
So now extremely detailed map [laughter] organized polarity. organizational photographs and uh we are here when we're collecting the data we are having software that allows us to produce maps and understand the resources of the distribution. So uh here you can see how the sharks that we caught on this last survey were distributed on on Kenyan waters. The small pelagic fish that we caught where they were distributed and the the abundance that we have estimated for the two years. This year we had the possibility of conduct conducting more tense surround allows us to reduce the uncertainty of the viruses that we have.
>> Correct. The data is much more accurate.
Yes.
>> Mhm. and we have obviously if you have any questions [music] we have a small main compiling uh and I would like to ask whether >> wherever you outside. It's almost ready.
>> Yeah.
>> So, how do you do this, baby?
What do you think?
>> Uhhuh.
So how how long I started to ask that 3 weeks that [clears throat] I don't know you got a scholarship.
Yeah. So we did together. Yeah. So where is he?
>> The last time I told you he was in Yes.
I know.
Okay.
Uh we have already done two last year and this year and this year the last year we made the northeast no succ the the aspect of doing it within the other the two seasons is that our productivity and fishery is different is determined by the productivity in different seasons. So the sound is consumed and that is the kind of information because we don't have very good information.
>> Uh because each vessel is state of the earth >> it has some sounders they they can release sounds and tell you the kind of waves that are happening the currents beneath at different levels. So these ones enable us to understand the productivity system within our north Kenya banks because that's where we have our tutors and the tuna normally come during these seasons >> in July.
>> So they they they have to be drawn by something and because they have to come and feed >> so what is causing these fish to be there during this season >> you need to understand and it's very key for management. So what we we we apart from everything that was key information that we were able to derive that uh the currents are very strong.
>> Yes.
>> During the southeast monsoon >> yes >> in fact you quantify the speed in north they flow at 4.5 knots which is very very high speed. M.
>> So what happens is that they meet with this the bank that we call North Kenya banks is a mountain >> in the sea >> and that mountain traps sediments from Tana River.
>> Okay.
>> Which are rich in nutrients and these sediments comes the Tana river brings in about 7 million tons of sediments.
>> Yes. So what happens is that these currents as they flow they come and they they heat on the mountain during the southeast monsoon and then they cause this tabulas >> the nutrients are both to the water column >> and then it becomes very productive during that time.
>> So that is the season that our waters are very productive but the downside is that at that time the seas are very [clears throat] rough.
So what happens is the tuners come they feed on our waters and the drug we cannot get the locals don't go catching >> and it's within our territorial waters the locals don't come catching so what happens is they come and feed and do their things and then they go to the e if you look at the VMS >> you find international vessels just on the borders of our waters waiting for tuners to So I think having the best [laughter] the information that can be done is to enable fishermen especially during the southeast monsoon you have vessels that can at least go for 3 days to 4 days uh and can be able [clears throat] to withstand the waves withstand the waves because they don't go they don't go out they come during the northeast monsoon the northeast monsoon the tuners have already gone There are fish there but they are not as much as you already developing [clears throat] characters. Yes.
And by the way tuna tuna is the most comfortable catch. Yes. And uh yellow feet. Yellow feet. Okay.
Okay.
So this is where [music] this is where we have already species. Yes. Yes. So some of them are going to to verify so that we can come or variables of what already exist. Yes.
Maybe sometimes because of geography where slightly different [clears throat] for the visits that we But I already have been present already.
This is only a very small yellow selection of the 399 species in green, you know, on the on the Yes.
the same.
Yes, we are going back because this one is supposed to be human.
This this is the one that expands when it is removed.
>> [clears throat] >> Uh this fish is actually a very very idle fish [clears throat] of the water. So so that's why not in deep water. [laughter] That's why that's why you have a myth that if you take this fish you will be sleepy like this fish.
from this year.
So the human error is minimized and the reason why we are selecting space information management essentially.
Yes.
Yes.
[laughter] Then information collected analysis everybody and Scientists do not be able to do it on their own.
Heat.
Heat.
Thank you.
