excelsiorfarm: i dont think anyone is avoiding your question. I guess u are interested in weight gain, u need a drug that would aid FCR,aquapro & livestovit will assist,note no magic about it,if yr fishes are 600gram & u expect to hit 1kg in 17 days,u could have starter earlier, clean water will aid better eating rate in fishes,use of aerators too

lansha2006: Please advise on how to enrol for the training in Benin republic.

TOPAI7: I want to appreciate the contribution of everyone on this forum. Am an ardent follower of this thread. Recently I engaged the services of an expert to spawn for me. The broodstock (female 4kg), male (3.2kg). The egg and sperm were good by what the expert said.

The irony of the spawning was that, no fry survived. My question is this:
(1) What should be the pH, temperature and other key parameters for spawning?
(2) The spawning was done in an open tarpaulin pond. Could this be a result for the mortality?

Thanks in advance for your ever constructive comments.

TOPAI7: They did last the spawning period. Few eggs hatch. More than 95% of the eggs were white by the second day. I suspect that the pH was low (6.00).

The pond was washed with salt as earlier advised in this thread.

The pond is directly under a coconut tree (I was thinking that low temperature might have affected)

There was flow through but it was not constant.

cachiskky: hello house, still on the subject of wounds. i discovered that the tail end of my fish are almost gone like u could practically see the bone of some. somebody suggested pottassium permanganate to treat the fish. please what are the gains and the dangers of this method of treatment because the fish are dying. i use earthern pond. please help

mozek24: On the contrary, I kinow a farmer that usually overstocks his pond, uses his formulated local feed but hits an average of 2kg within 6months before sale. Where a normal farmer stocks like 1000 pieces, this man would stock between 3 to 4000. How does he do it?........... Simply clean water. He does flow through. His bore hole is on 24/7. Has a standby sound proof gen.

He uses a limited space but produce more. Though this is not advisable to begginers because of d associated risks and cost. But am looking towards that approach. It saves cost in the long run.

What do you guys think??

Space do less or jampack and apply technology?

mickyfish: Oga robonski, excelsoirfarm n others I want 2 use this medium 2 say more pawers 2 ur elbows 4 all u guys r doing, thousands of nigerians r benefiting 4rm dis tread including mysef n anyone who wants 2 cuz confusion here God 'll expose their evil act, thank u all n God bless u all.

mickyfish: ur fishes r suffering 4rm tail n fin rot(PENDUNCLE DISEASE). The causes of this kind of disease r 1. Protracted low temperature, dirty living conndition n damages and weakness caused by other diseases. The treatment 4 dis kind of disease is ANTI-BIOTICS n improve water condition(water quality) no amount of salt'll work @ dis stage, mind u too much of salt can kill ur whole fishes. Just treat dem wit d recomended dosage of anti-biotics u r to use thank u.

It is not advisable to make use of PG in earthen pond. I've posted ways by which you can treat your fish in earthen pond in my previous post on this thread. You need to get the following items; salt, NCO and Ashes(eeru).


The amount of salt to get depends on the size of your pond eg in a 30 by 40 meter pond, I use 20 to 30KG of salt.
A sachet of NCO is between N900 to N1000
Ashes, that you can get freely from any local bakery around or people that make use of charcoal to cook or make boli(roasted banana)


Here is the application of the above stuff:



1) Drain the water in the pond with the use of your water pumping machine.
2) Leave little water in the pond in such a way that it will cover the fish
3) Then, mix the three items together ie salt, ashes and nco.
4) Sprinkle it all over the pond, do make sure it covers everywhere
5) Leave them for like 30 to 40 mins, after which you allow fresh water into the pond


Before I tell you what next to do, let me know how old the fish are.

thanks for getting back to me. the fish are 8weeks old


Cheers,

excelsiorfarm: op how old are your fishes(fries) & at what age do u sell for fingerlings & juveniles?

mozek24: Topa17. I will advise you try again. I had a similar issue in July this year that is my first hatch. I paid this professional 30k (workmanship) to hatch for me. He provided every other material which cost me an extra 40k.he brought 3 females and 2 males each not less than 4kg. Day 2 after spawning everything disappeared, water turned milky. I lost almost 100k. I contracted another pro who introduced local re circulatory system. I told him my past experience. He advised we use a re circulatory system I said ok as long as it works. Construction alone gulped almost 150k, 50k labour, 8 brood stocks of 4kg each @ 2000. (Y 8? 3 of d males don't hav sperm sac and the biggest died before daybreak). I spent about 220k yet they lasted only day 2 after spawning. I was so angry I told the guy to return my money. Did I see ten kobo?
He blamed it on water cos every other material thing was in place.

I nearly gave up on hatching. My wife encouraged me try again this time on my own. I was so scared that I used a male and a female of about 1.5kd each. Guess what ? It came out very well, my wife and I were jumping up and giving testimonies. I did the same thing I saw those pros do! We got about 3000 post fingerlings. And it gets even better since then using the same water undiluted/reguated.
Now it costs me less than 10k to hatch while expecting a minimum of 6000 fingerlings.

I will advise you visit a farm or attend another training then try it on your own. No big deal.
I am not again testing your water ph, just that sometimes your ph will be ok yet they die like in my case.

robonski15:

My fries are 4 weeks and two days old.. I sell my fingerlings at 8 weeks and juvenile at 12 weeks.. It also depends on how fast they grow!!!

TOPAI7:

@ mozek24
Thanks so much I will not give up as you advised.

@robonski
I will checked the pH again. And try spawning again. (In your words, if one has not started hatching, one has not started fish farming).
