excelsiorfarm: @all, the fact is recirculatory outweighs all system, no argument about that, lets focus on how people can do better in their respective pond system

I bet to disagree on that note. Flow through system is far better than any other system. Recirculatory system helps to manage water where water is not sufficient unlike flow through where there is constant water from time to time. It is a total mistake to conclude that a recirculatory system is better than a flow through system. It is less expensive to maintain perhaps it does not cost u a dine and ur fish will perform greatly.

I couldn't agree more.. We should learn how to be more productive irrespective of the pond system we use.. Some folks have failed in this two type of pond system.. We should endeavour to bring out the best in whatever system we use.

excelsiorfarm: i have no reason to question your judgment, but if indeed your conclusion is right,i guess the world over, that system will be the in thing,unfortunately it isnt. Learn from d major fishfarmers, none does flow thru, fishes in recirculatory ponds are healthy, the biofilter creates a great environ for growth and saves water.flow thru is a poor idea of recirculatory,from the v best in norway, to isreal , the world over, everyday they are improving on using less water to produce more fishes, durantee can be another eg which was once air on CNN

lagbaja:

A flow through system has to be recirculatoryto be ok unless u have a freely flowing stream to use. That was probably why the one Robonski reported failed.

One of the major factor to consider is your environment. We are Africans and not european countries where their way of life is different from ours, where earth quake, volcano, ocean surge happens although technologically they are ahead of us. It is no doubt too that Africa is more blessed in terms of natural endowment. Most of the method u highlighted is put in place as a result of cost they incurred in getting water, payment of electricity bills and so on. Whereas, all of the above can be gotten freely. Catfish performs fine in earthen pond where you can make use of free flowing water and it does not cost you a dime to maintain. In a situation where your fish weigh btw 2.5 to 4KG without spending any money on powering any thing, then u sure should know that the method is indeed a very good method. It is entirely wrong to conclude that recirculatory system is better than flow through. It is wat you know better that you will talk about not generalizing please. Moreso, d essence of any method is to reduce cost, maximise profit, reduce stress.

excelsiorfarm: my bro, it isnt a contest of which prove my facts is ok, i can suggest u visit good recirculatory farm and ask them if at the point of harvest if d cost of fueling tells on their ROI, eg ajanla,durante is in naija, i know one in bodija,on barely half a plot, another in lagos around oke afa, byond saving water, u have lesser land use, u need not damage d environ etc, so d tech applies to naija if one can establish one, eg aside environ northerners get better harvest because they use improve seeds and know- how(talking from experience). Whatever system any man choose to use,just get the best & make profit

lagbaja: It is obvious that you are refering to natural flow through systems. Either the ones with cages in rivers or streams. it is not every farmer that has access to free flowing streams. It is also not logistically conveneint to farm far away from where you live. You are also subjected to many security risks. It is diffcult to control predators in flow through systems. Recirculatory system is urban friendly. I have seen it done in a small room. Also, Yield is not measured in sizes of individual fishes, It is measured in total biomass over a given period of time. Recirculatory systems support high biomass density than natural flow thru systems. It is also difficult to control diseases in flow through systems unlike in RAS.

williams20: Good day farmers , ill like to appreciate Mr Robonski and others on this thread , pls ensure you research well about your fish source before you buy any fish from anyone - they might just be runts as I've been a victim and I've learnt in a hard way. I'm getting over it tho. And for those having problems with feed , I've been usingZeigler for about five weeks now and I must confess Its the Best , its.a perfect feed ivent recorded any deaths or casualties that is feed related . God bless Nairaland and everyone .

OLISASDEJI: @william and roboski,am in abuja.am a fish farmer.i av never set my eyes on ziegler feeds.wat am used to is coppens and multifeeds.

TOKUGAWA: The Minister of Agriculture and Rural Development, Dr. Akinwumi Adesina, said on Tuesday that the Federal Government would soon place a total ban on the importation of fish and other aquatic consumables.

Adesina said this in Ado-Ekiti during the inauguration of the Special Growth Enhancement Support scheme for fisheries and the aquaculture value chain, according to the News Agency of Nigeria.

He, however, said that the ban would be imposed only if arrangements being put in place by the government to that effect worked as planned.

The minister, represented by the Federal Director of Fisheries, Mrs. Foluke Areola, said the country had no business importing fish, given its huge natural and renewable resources.

He said it was in view of this that the ministry was promoting increased fish production through the aquaculture value chain.

This is in pursuance of the goal of the Agricultural Transformation Agenda of the Federal Government, he said

"The value chains are to create an enabling environment for increased and sustainable production of over one million tonnes of fish within the next four years, generate employment and pursue gradual reduction of fish imports," the minister said.

Adesina noted that the aquaculture value chain, under its four-year implementation plan, would increase the annual production of fingerlings in the country by 1.25 billion tonnes.


So my co fishpreneurs,lets hope the FG is serious this time around cos this is a very good news.Imagine a kilo of melaunge selling for 400-450 Naira?

Tosade01: Good day to all the gurus in the house, this iƨ̣̇ one of the best thread ve ever seen. God will surely bless you all for the good ω°rK here. Amen.
Please I need someone to give me the cost and size of concrete pond that can house 800 and 700 each from fingerlings to Grow Out/Table size. Also, Mr Ab1x said changing of feed iƨ̣̇ not good. I wanna ask that if you purchase juvenile and the seller used coppens. Can I feed them with ziegler.
Have a great day

practicalclass:

1) Is a kilo of melange to cheap or too expensive for N400-450?
2) i thought melange is catfish not up to 1kilo i.e. melange is catfish if abt 600g (0.6kilo), so why say a kilo of melange?

practicalclass: Pros in the house, i washed one of my concrete ponds with brush abt 3 wks ago and since then it has refused to hold water. Any solution. Thanks.

robonski16:

1..A kilo of melange presently is #350 for catfish upto 500grms or 0.5 grms which is half a kilo.. Now if u raise ur melange upto 0.5 grms and sell at the rate of #350 is ok..

A kilo of table size is #480 in lagos, if u divide this amount it gives us #240 which is not up to the amount of the price of melange which is half of a kilo..

2. Melange is sold in kilos,if you add up the sum total of all the grms it will automatically be converted to kg..

robonski16:

The pond was not properly plastered hence the leackage..from my experience With time it might coat back and the leakage will stop, but when you re-wash it starts to leak again..

Call a brickyaler to work on it when its empty..

practicalclass:

Its getting it plastered well that is the issue so the same doesnt repeat itself. I mean what amount of sand should be mixed with cement so it can be tight and hold water.

robonski16:

A concrete pond of 8 by 8 feet and 8 by 7 feet can house 800 and 700 fishes from fingerlings to grow out respectively..

U can change feed but as ab1x advised that you treat the fishes first b4 changing feed..
