Thanks sir. Can I use antibiotics again, cos I've used it once when I stocked, but didn't use after I changed the water.

Dear farmers, I started reading this thread from the beginning. Feels like I have attended a fish farm seminar with all the lectures, challenges an solution proffered. I want to appreciate all (Rob, Ab1x, Excelsoir Ayosat just to mention a few) who have been their brother's keeper God will surely bless you all. AMEN

Please house I will be stocking my earthen pond o Friday with juveniles. I limed it and net it last week and pumped out the water yesterday. After pumping I discovered there were 2 or 3 averagely grow frogs and tapoles. wte killed the frogs but left the tadpole. My concerns:

1. Will the tadpoles serve as food for the juveniles?
2. It appears the liming was not as effective due to the presence of the tadpoles. Though on the very day of application alot died. I don't know how they got in again. Should I be worried?
3.What should I give them to reduce the stress of transportation?
4. As prevention is better than cure. What best practices in terms of medication can one adopt to prevent diseases.

Thanks

Why not ask here so long its related to fish farming, so others can learn..

excelsiorfarm:
Amen to your prayers in Jesus Name,Amen.

let me answer your questions, the tadpoles would serve as food provided your juveniles in question are well develop in size, because their numbers are usually much and they grow fast into frog,better they are small or your suppose juvenile could be consume if they outgrow them quickly.
the lime was effective, but when you lime and there is water, effectiveness could reduce, in such cases you re-lime. the unhatched eggs during application are what you are seeing now as tadpoles. I would even say, your one week isn't enough time for development of the effectiveness for bloom of plankton in ponds. hence in all, make sure your juvenile is really juveniles or you could loss all(writing with experience).

for transportation, from where to where? whichever distance? ask your breeder to starve them for a day or two(duration depends on how far the distance), but i expect a good or experience breeder to have ask all this taken precaution on the behalf of the buyer. Add a few drops of palm oil to their water so the water doesn't foam and for better transportation medium.

A good fish will not need any medication immediately

Hello house please I need your help on this. My husband wants to invest in catfish business. He has never done it before and we have no idea the cost involved. We are thinking of starting with 1500 juveniles and breeding them for 4 months. Please what feed do we have to give them at every stage- from the 1st 2 weeks to the 4th month?..what is the cost of the feed and how long does a bag usually last for the quantity of fish we intend to rear? We are just trying to get a rough estimate of the money we will put into feeding them. Thanks for your response

fullman:
Am just buying a 8ft by 18ft by 4ft tarpaulin.
Please guru can it take up to 1200fishes for 5month as the seller claims.
Also what should I do to the tarpaulin before putting the juveniles.

Thanks

excelsiorfarm:
@igchuks, i dont know the timing from tadpole to frog,but i know before you know it they are all grown up. If the picture i saw is exact size,i think the tadpole should be 2-2.5 inches. A standard or reasonable juvenile should not be less than 4.5 inches in size. Evaluating this,it might be a challenge for the juvenile to feast on them,moreover tadpoles normally in most cases would have higher number on their side. About transportation for just 2-4 hours? let him feed them today,no challenge,but should not feed them on the day you intend to pick them. That distance time not much. I believe the breeder knows that. Ensure you add few drops of palm oil into your water in the jerry can with the fishes to avoid foaming,reduce stress.
About the two feeds,they both have good report.

igchuks:


Excelsoir thanks again.
Finally took delivery of 5000 post Juveniles and juveniles. I had 6 50lts jerricans. I put 1000 in 4 of them then 500 in the remaining 2 jerricans.I recorded some mortality in the 50ltr with 1000 and none in the 500. It took about 4hrs to get to my farm. Guess the number was too many. I learnt my lesson. The juveniles chased after the tadpoles to eat them and alot of them ran out of the pond. Feeding will commence tomorrow. I really appreciate your advise

excelsiorfarm:
Thank God. did you count the cost before taking 5000 or are you targeting melange,also what is your pond size? What is mortality figure & how big were the juveniles? lets see your pond & give us the state of your fishes & how you transported them? water volume etc. to have suffer mortality

Gurus In the house, does anybody know the quantity of poultry manure (weight in kg) to apply to a pond on 11 feet by 7 feet with a water depth of 50cm to fertilize my concrete pond for transfer of fish fries.
I do not want to over fertilize it.

igchuks:


The target is melange. I have 3 earthen ponds measuring 40x24x3, 40x20x3 and 40x18x3. All in ft. I know it will gulp alot I have planned for it. Mortality could be btw 50-100 though I couldn't count as they are yet to surface and float. Unless a miracle happened and they are alive. Generally they are doing fine and I moved feeding to tomorrow morning. The transporting medium was a 50L jerrican filled with water a little above the middle mark. I did add a lil red oil as advise. I believe the mortality was as a result of overcrowding because there was no mortality in the jerrican with 500 juveniles. Attached are pics of the juveniles and pond

igchuks:


Apply inorganic fertilizer at a rate of 2g/m² or 2g/10.76ft²
Apply organic fertilizer at a rate of 50g/m² or 50g/10.76ft²

For your pond multiply 11x7 then divide by 10.76 = 7.2
So you should be applying 50x7.2g of organic fertilizer

Good morning esteemed entrepreneurs,
I am humbly coming to you because i am having an issue when trying to calculate the cost of raising 1000 fingerlings to table size, so that i can plan my entry into this business properly. I have this calculation as of now based on my research but it seems pricey. My per unit cost of raising one fish to table-size comes out to 572 naira per and that is not enticing at all. Please can anyone pick apart my calculations and enlighten me as to the error of my ways. All constructive criticism is welcomed.

Thanks, I intend to put the poultry manure in a tied bagco bag and lower it into the pond and leave it in for 10 days before I stock my fries. From the calculation above I will be adding 360g of dried poultry manure into the bag and lower it into a pondOf approximately 50cm to 70cm depth of water.

Do you think this quantity is enough to adequately fertilze my pond and give it the fresh greenish colour within 10 days? Or should I increase the quality to 2kg since it is not thrown directly into the water?

Because some farmers I know just throw the poultry manure directly into the pond without putting it into a bag, but I think this method will easily polute the water faster.

Also another question is, if I fertilize the pond how often do I need to change the water in the concrete pond to siphon out dirt or do I not need to change the water at all.

Please advice.

igchuks:


Sure it will. It is the recommended quantity. However, a little above will not harm. It is meant to add microorganisms to the pond that your fries will feed on. You can either broadcast it like the other farmers are doing or put it in a bag. You will need to change your water every 3 days.

igchuks:
@Excelsoir sure he did. Thanks

excelsiorfarm:
seen,your seller should have given you 2-3% of the stock bought. Its well.

All the best
