00:00 In Laguna, there is a small island that rests beneath the sea.
00:04 It is considered a treasure for fishermen who rely on it for their livelihood.
00:11 But what they don't know is that these islands are not only treasures,
00:17 but also a thorn in the life of the sea that they rely on.
00:23 Find out the details in this video.
00:25 Are you running out of ideas for your UOTD or Ulam of the Day?
00:32 Some of us probably have a favorite fish.
00:36 To those fish lovers out there, have you tried the golden fish?
00:42 But this is not the goldfish that is in your aquarium because this fish is like this.
00:48 It is caught in the City of Seven Lakes in Laguna.
00:55 In this vast area here in Laguna,
01:03 there are many places where you can see the fish swimming in the water.
01:09 According to the residents here, the fish we are looking for is spread in this area.
01:15 This is one of the livelihoods of the residents here.
01:19 And it is not just a fish or a medal, but a fish.
01:26 And to help us find it, we will be joined this morning by one of the fishermen here, Brother Jeffrey.
01:32 Good morning, Brother Jeffrey. Where is the goldfish?
01:35 It's in the water.
01:37 Let's find it.
01:42 To find it, I need to ride a boat first.
01:46 It's in the water.
01:51 Are there really a lot of goldfish here?
01:56 There are a lot.
01:58 Is this it?
02:01 Yes, that's it.
02:02 This is it.
02:10 It really looks like a goldfish.
02:12 Because of the abundance of fish in this area, their colorful goldfish is getting scarce.
02:19 And in this floating cottage, there are more goldfish.
02:30 They are called mydacyclids or flowerhorns by the residents here.
02:38 Their name is inspired by the Greek god, Mydas, because of their color.
02:43 Aside from the abundance of goldfish, there are also some gays that are around here.
02:54 Are you really breeding mydacyclids here?
02:57 Why are they here with tilapia, bones, and koi fish?
03:01 Sir, they are caught outside.
03:04 I'm just making a memory.
03:07 A memory for?
03:09 In case one or two of them are gone, I'll just keep my fish cage.
03:16 So you're really mixing them with tilapia?
03:20 Yes, so that it looks good.
03:23 It also has flowerhorn, a type of fish that is usually kept in aquariums.
03:29 I'm with one of the biologists who noticed these mydacyclids.
03:35 Sir Greg, what's special about it is that it has a ball-shaped head.
03:41 For aquarium fish hobbyists, they like fish like this because the local hump or ball on the head is to make the fish prominent.
03:54 So the bigger the ball on the head, the more the aquarium hobbyists like it.
03:58 And the color is so vibrant. It's orange.
04:01 It looks like goldfish at first glance.
04:05 In 2013, this fish started to be seen in the bay of San Pablo, Laguna.
04:10 When the Glenda Flood happened, we noticed that.
04:14 That flowerhorn.
04:16 They said that someone was breeding here, but when the Glenda Flood happened, it disappeared.
04:21 But this mydacyclid is not easily noticed by people.
04:26 In fact, a piece of mydacyclid is only worth 5 to 10 pesos.
04:32 I bought it, but it's not like the tilapia that you can buy in the market.
04:37 Because?
04:38 Maybe people don't know it yet. They don't know the fish.
04:41 Who buys it? And where do they bring it? What do they do?
04:44 They eat it.
04:45 How much do you sell a flowerhorn?
04:47 I bought 60 to 50 per kilo.
04:52 All sizes, small or big.
04:55 Is it for sale?
04:56 No.
04:57 The bright color of this fish is very attractive.
05:04 But its presence smells fishy.
05:09 These mydacyclids are considered an invasive species.
05:15 It means that it is a threat to the population of native fish that have lived here in the bay.
05:21 So this is what they call a mydacyclid.
05:26 Because if you look at it from below, you can see that the color is very distinct.
05:31 It looks like a mydacyclid.
05:33 The problem is, this mydacyclid, Sir Greg, is an invasive species.
05:38 Invasive? That's not good.
05:40 In this bay.
05:41 Because invasive species can displace and completely destroy our native and endemic fish.
05:51 So if we don't catch them now, there may come a time when our lakes and rivers will be full of these.
05:59 First of all, the fish that are far away.
06:02 It is dangerous for the economy and ecology of this bay.
06:10 Yes, because this bay's true inhabitants are the native Philippine fish.
06:17 And the size of their heads also has a connection to their resilience in nature.
06:23 The size of its head is big and you said it is one of the smartest.
06:29 Mydacyclids are really smart.
06:31 So that's why they can easily become an invasive species because mydacyclids are naturally brave.
06:39 So mydacyclids are really a fighter.
06:41 And they have a good trait in that they are good parents.
06:46 They are very good parents.
06:48 Mydacyclids' parents are closely monitored by their fingerlings.
06:53 So they can multiply faster in freshwater ecosystems.
06:57 Mydacyclids are sexually dimorphic.
07:00 It means that the appearance of the male is different from the female.
07:03 The nuchal hump is bigger or the head of the male is bigger than the female.
07:08 Wow, look at this. It's big.
07:11 It's bigger than my hand.
07:13 It's like the size of tilapia.
07:16 Although they are called goldfish, their behavior is different.
07:20 Because goldfish are calmer than mydacyclids.
07:24 They have an aggressive behavior.
07:27 They fight other fish that live in this bay.
07:30 In fact, there is a study that found a dozen species of fish that can be found in this bay.
07:39 Out of all of this, only three are native or are considered to be found here.
07:46 They are the ayungin and the two species of biya or bottom-dwelling gobies.
07:52 Everything else we see in this lake, from the golden mydacyclids to the tilapia to the bighead carp, jaguar guapote, koi, and many others have been introduced from other countries.
08:08 So for the best alternatives, instead of concentrating on foreign fish like mydacyclids,
08:17 let's study the true value of our native fish.
08:23 By learning to value what we have, we can protect our rivers and lakes from foreign invaders.
08:31 Mydacyclids came from Central America or from countries like Nicaragua and Costa Rica.
08:44 Only a few native fish are caught here.
08:48 There's an ayungin here.
08:51 This is an example of a fish that lives here.
08:54 It's so small.
08:56 Look, sir.
08:58 There!
08:59 It's a piece of ayungin.
09:00 It's a piece of ayungin.
09:02 This is not called ayungin.
09:03 This is a fish that lives here.
09:06 It's really small, sir Greg.
09:07 The ayungin is getting bigger.
09:09 But if we can see, Jonathan, this batiang is just a small piece of native fish.
09:17 And it's not good.
09:18 It's not good because before we fully appreciate the use of our native and endemic species,
09:25 many of them are disappearing.
09:28 They are becoming extinct before we can talk to them and understand them well.
09:36 One way to catch and eat them is...
09:40 ...edible.
09:49 What does it taste like?
09:51 So, this is the Mydacyclids, also known as flowerhorn.
09:55 It's fried.
09:57 Let's try it.
10:04 It's like tilapia.
10:06 And the meat is really juicy.
10:10 It's more juicy than tilapia.
10:13 And I don't know if it's just because it's fried but the meat is really juicy.
10:19 It's delicious.
10:21 Mydacyclids are from Central America or countries like Nicaragua and Costa Rica.
10:28 Mydacyclids.
10:29 It's just a small number of native fish that can be caught here.
10:38 There's an ayungin here.
10:41 This is an example of a fish that lives here in La Jolla.
10:44 It's so small.
10:45 No, sir.
10:48 There!
10:49 It's just a piece of ayungin.
10:50 It's just a piece of ayungin here.
10:52 This is what we call ayungin.
10:53 This is the fish that really lives here.
10:56 It's really small like this, sir Greg.
10:57 The ayungin is getting bigger.
10:59 But if we can see, Jonathan, this batyang is just a small piece of native fish.
11:07 And it's not good.
11:08 It's not good because before we can fully appreciate the use of our native and endemic species,
11:15 many of them are disappearing.
11:20 The reports that come to BPAR show sightings in other freshwater areas.
11:27 So our proactive response to that is to have an ongoing profiling in Calabarzon
11:35 to see the extent of proliferation of mydas.
11:41 In the partial results of the analysis, we saw that there is almost no proliferation of mydas.
11:50 Hopefully, our profiling will be completed so that we can see the correct data.
11:55 What is the status?
11:57 But basically, our partial result is that there is no market value for mydas.
12:04 This program and its effective implementation is what is needed in the issue of the proliferation of golden fish in San Pablo, Laguna.
12:13 If it is not caught, more can be produced.
12:17 Hopefully, the ginto of our natural wealth will not be a waste.
12:22 The ginto that spreads here in the seven lakes of Laguna is not really considered ginto but tanso.
12:29 Because of the conservation of the environment, native species or the Filipino fish that really live here are considered endangered.
12:38 So, fellow brigade, be careful in the care of the animals that are not really seen here in our country.
12:45 I am Jonathan Andal, with the IISang Brigada.
