Survey River: Along Suai River from Suai Coastal Bridge Up river.
The 13 Km boat track of Suai River and Display trees of Firefly survey.
Suria and me planned to go for freshwater prawn fishing at Suai river on the 26 of February. According to our fishing info the prawn are already feeding and they are huge one to be caught. The huge are called “Apek” or “Agang”. However, during this time the difficulty of renting boat is clear due to a lot of demand. Normally we would go as early as possible to get hold of the boat. Then we either sleep in a boat or some preferred fishing at night, while waiting for the day light.
We started our journey at 6:00pm and reached Niah at 7:00:pm. We need to borrow anchor from my uncle, we forgotten to bring ours. Then we go to Suai bridge and reach it at 8:00 pm.
We off our fishing gear and set to go up river. Due to salt water coming into the river, this time around we should going up to get fresher water, where those “Apek” resides.
Just before we turu up river a few feet from our berthing place there is a firefly display between the Nipah palm. We go there and scoop a single firefly. When I want to put the firefly into a sampling bottle, there were 2 fireflies in the net. Then we set off to do the fireflies survey going up river on the left side of the river. The Right side is already cut for oil palm plantation.
The first WPt is at 515 with some 30 individuals. We went along the river that recording the fireflies display trees. Along the river there are many people spearing prawn.
We finishes our survey at WPT573 at 22:54. We move on there is no more display tree. We stopped at WPT574 and set up anchor to do prawn fishing. Not within minutes we already caught one “Apek”. I was not keen to do night fishing and goes to sleep. Suria fished the whole night and keep awake to watch for crocodile. I sleep like a rock just to wake up when I heard hornbill calling.
Black horn bill close to where we fish.
Along the fishing trip we encounter 7 Black horn-bills, five emperor green pigeons.
Pwawn caught.
We fished the whole day and caught some 2 kg of prawn. The day is too hot that I have a heat stock.The air temperature is 34.8° C. Then we have to fish under a shade that is not very good fishing area. We set off to the jetty and along the way taking photographs of the display tree. We set to go home at 5:30 and marked the coordinate of last night firefly display tree.
These two hornbills woke me up.
We have a drink at the canteen and set off to Telong Lake. We want to do snakehead casting there. We reach Telong and do snakehead casting for half an hour. There are few motorcyclist just finished casting and caught a number of snakehead fish. We caught none and go back to Sepupok Niah to return the Anchor.

At Sepupok we have a dinner at the foodstall. The people there told us no today not good prawn fishing. We wait for the darkness because I plan to go to Kuala Sibuti feeder road/. I have noted an area of potential firefly display.
It was 7:47pm and the sky was still bright. There is a full moon shining.. We went all the way into Kuala Subuti Kampong and there is no fireflies display found. When we go back out of kuala Sibuti we started to see fireflies display. We saw a lot of fireflies but the moon light hide the. We stop just after the small bride and there are plenty of fireflies displays and they are considered the best I have ever seen. Nearly every foot of the area is lighted by fireflies. This area is about 100 meres long along the road.
We stay there for a while and set home at 9:30pm.

Remarks:
This area is a good CFZ but it been treatrned by oilpalm and human activities.
The fact that the fireflies display in Nipah palm is that they are trying to adapt to the changes. But soon or later it just goes extinct like the other area.
