Netting Fish at TPU pond UPM

Salam,,,

Long time no see, mybe i'm busy asissted Ph.D student (Mr Lawali Alkali Argungu) in the lab doing fish hormonal profile lab work, then have no time to update my blog. mmmm...the story is not today but last week, my master friend call and asked me to help her in a pond. She said they need men power to netting fish in one of TPU pond UPM. She want to select black Tilapia from the pond as her master project experiment which is about polyculture with snakehead. So at the day in the morning around 10 am we start gathered and discussed how to conduct the task. There was only 4 men and 5 females that will hold the net to trap the fishes in the pond. 

The pond that we netting the fish, very big right??

Make sure the fish not escape from the bushes

Because of the pond really large we need to make it into 4-5 round to cover, Fuhh....

Remove all the rubbish such as branch tree, leaves etc.

Got big Grass carp, kita bbq la ape lg,,haha

Got a lots of Black Tilapia still not enough need to make 4 more round..

Got "Ikan Patin" or Pangasius hypophthalmus big one.

 Passionate netting team :)

Move the fish from TPU pond to Puchong tanks by truck

Wonder team, other two men power not here..Happy work with u guys.. ;)

Please Call me again if u need help.. Don't Hesitate, my pleasure to help and have fun :)

Sexing Goldfish (Ikan ni Jantan ke Betina??)

Salam & Morning,,,

Many not know how to sexing goldfish. Even ornamental shop staffs and owner confuse to differentiate male or female of the fish when i asked them. Sexing goldfish is very difficult before they reach maturity. Sometimes people can tell by looking at the shape of the Vent. Females may have rounder convex vents while males have thinner concave vents. The pectoral fin of males may be rather thick and stiff (compared to those of female goldfish) and with a more pronounced outer ray. Some people also believe that male goldfish have longer pectoral fins than do female goldfish.

First, we should know about Internal and external features of Goldfish:

The following pictures will help you determine the sex of your mature goldfish.

Breeding Stars or Breeding Turbercles

Male goldfish with breeding stars/ tubercles on their gill cover (Operculum) and along the first ray of their pectoral fins when they reach sexual maturity.

Male Goldfish

This picture of my Mykroll's red capped orandas shows the stars and thickening of the pectoral fin of the male (Compared with the female). The female's body is also more rounded than the male's.

Vent

(Male)

When goldfish are ready to breed you can observe changes to their vent area. Below are pictures showing the vents of two mature male. The vent is longer and is indented (concave). This is a lot easier to observe on a mature fish who is ready to spawn.

(Female)

Below are pictures showing the vents of two mature female goldfish. The female vent is not as long but it is protruded (Convex).

Behavioral Changes

It is the female that really "controls" the breeding. A female goldfish (not ready to breed yet) will send out pheromones (a types of steroid) which will encourage males to produce the milt. When the female is ready to breed she will release another type of pheromone that stimulates sexual behavior in the male. The male will react by checking out the females, nudging them in the vent area as you can see on this picture. Males may exhibit this behavior before the females are ready well, but it will be fair intense once the female is prepared to prepared to spawn. Once spawning starts the males will chase and bump the female until she release her eggs.

The Result

The female should release eggs that will look like these.

The Goldfish in tanks will eat the eggs, so if you want to raise fry you will either have to remove the eggs or the parents. Here is picture of a 19 days old goldfish fry.

Happy sexing and breeding Goldfish..

Pulau Ketam Cage culture & Xian Leng Aquarium Trips

Fuhhh,,,what a nice trips..Really enjoy the moments and knowledgeable.

U also want to know where i went today (30/05/2012) right??...Today i have an opportunity to follow a trip to Pulau Ketam together with undergraduate students taking Live Feed subject with Mr. Abdullah (Lecturer). We not actually went to Pulau Ketam but we went to Marine Cage Culture under a company KS Aquaculture Sdn. Bhd.. To go there we must rent a boat and departed nearest KTM Pelabuhan Klang (Jeti Penumpang Pulau Ketam) to the Cage Culture. The time to go there taken about 30 mins to arrived.

We take 2 boat that can fit 13 person each. At the Jetty we are welcomed by QA KS Aquaculture Sdn. Bhd. staff Miss Laura. She is really nice person and explain all the thing that the cage culture work on. we got a lots of knowledge from her explanation about Marine cage culture industry.

After introduction with the staff that handle this cages, we were brought to the site where they going to feed the fish. There were several species and fish they cultured here such as Tiger grouper, Giant grouper, Red Grouper, Bawal, Sniper etc. They also have several feed that they going to feed. For the small fish they gave small grouper pellet (43% protein, Taiwan), medium size gave more bigger pellet (43% protein, Taiwan) and for the big one they gave Scad fish/frozen fish (ikan baja). They said the fish gave faster growth rate compared to the pellet.

Grouper sinking pellet (43% protein)

Quarters for workers 

Memorable Moment :)

 After finish, we going back to the jetty for another trip. After this we planned to go to the biggest aquarium that sell several types and species of ornamental fish. The place called Xian Leng Aquarium.

Before we continue, we went to Masjid Shah Alam for Praying

The place not far from the mosque, then we continue.....

Good Bye..Sleep with big smile...:)

Javanese Carp ( Lampam Jawa) Breeding

Salam,, Selamat Tengahari..

This morning i have opportunity again to demonstrated how to breed Javanese Carp (Lampam Jawa) to undergraduate student that taken Aquaculture Principe under a lecturer Mr. Rozihan. This type of species i never try it before, then i have no experience to handle it. But i try my best to help the students how to conducted artificial propagation of Javanese Carp. Below is the detail :

1) Broodstock selection

The female will ready to inject when they have these criteria: having protruding papillae, big & smooth stomach. We can confirm the matured male when we applied slightly pressure on the fish stomach and the male will release sperm when they ready. 

2) Hormone Injection

Ovaprim is the right and effective hormone in induce ovulation and spermiation in this species. For female, we can use 0.5 ml/kg of Ovaprim and for male we used half of the dose 0.25 ml/kg Ovaprim. The injection will be 6 -7 hours interval from the injection time to the stripping (ovulation). This morning at 5 am. we already administered the hormone and will be stripped at 11 am. After injection, the male and female breeders will be separated until stripped.

3) Check for readiness

Before we conduct the artificial propagation, we need to check either the fish already ready or not. That mean we need to check the stage of the female eggs. We no need to worry much about the male bcoz they always ready. Applied slightly pressure on the stomach until the small batch of the eggs comes out. They not ready when blood comes out or attached eggs out. The good eggs when they were smooth release and give white or green in colour.

4) Artificial propagation

Now the time to do artificial propagation. The matured female was taken out first and stripped out the eggs into a dry bowl. Please take note: avoid more pressure when the blood out bcoz this blood will disturb the fertilization rate for the eggs. After that take out male and stripped out the milt into the bowl. Mix the eggs and milt using chicken feather for 2-3 mins (Dry method fertilization), then add fresh water (2/3 of the eggs volume) into the bowl then stirred it slowly for 2-3 mins. After finish, to avoid the water in incubator tanks got contaminated, make sure you rinsed the mixture with fresh water to removed debris comes from blood, sperm, protein particle, fat etc. 

5) Incubation

After totally cleaned, the fertilized eggs were transferred into incubator tanks. Make sure the incubator tanks equipped with aeration to give water movement and oxygen to the eggs. The egg take 24 hours to hatch..I taken some sample to my room to observed it closely.

Tomorrow we will see they hatch or not....
