Imported catfish feeds have some benefit over the native which incorporates: most imported feeds are floating feeds and thus don’t contaminate water simply in contrast with native feeds that are principally sinking feeds/pellets.
Additionally, being floating pellets, imported feeds should not normally wasted as most of them can keep on the floor of the water for greater than two hours, thus making them to have entry to it not like sinking pellets.
In phrases of nutrient worth, imported feeds are extra nutritious than the native feeds. Thus could also be because of the truth that most feed millers don’t give consideration to particulars in compounding fish feeds and thus don’t add all the required feed components to the feeds.
The key drawback of imported feeds over native feeds is that it’s way more expensive and as such, most farmers couldn’t afford feeding their fish on it for so long as anticipated.

Varieties of Catfish Feed
Since there are completely different levels of catfish progress, there are completely different levels of fish feed; fish feed are sometimes denoted in mm, so that you’ll see/hear about 1.5mm feed, 1.8mm feed, 2mm feed, 4mm feed, 6mm feed and many others.
There’s additionally extruded (or floating) and non-extruded (or sinking) feed.
What I like to recommend is to offer your fishes extruded (or floating) feed for as much as 2 months earlier than switching to the non-extruded (or sinking) feed.
Catfishes are principally backside feeders, so by their very nature they’re designed to be consuming non-extruded (or sinking) feed, however the cause I like to recommend giving them floating feed on the early stage is as a result of they’re extra fragile then.
With floating feed, you possibly can put the feed on the pond step by step and allow them to eat it; the danger of overfeeding is considerably lowered, thereby guaranteeing there isn’t any water air pollution that may result in excessive mortality in your very fragile juveniles.
Moreover, because of their fragile nature, giving your juveniles feed that isn’t wealthy with the correct vitamins can have an effect on their long-term progress; going with floating feed from acknowledged producers like Durante, Cargill Aqua Feed, Raanan, and Coppens will guarantee optimum progress of your fishes, even once you later change to sinking feed comprising of your individual components.
That mentioned, the highest feed producers that I like to recommend and have used are Aqua Feed, Durante and Raanan; I’ve heard that Coppens could possibly be the perfect, however there are tons of adulterated variations of it right here in Nigeria, so I received’t suggest it for the reason that inexperienced farmer may fall sufferer to those adulterated variations.
From my analysis, I’ve additionally seen that Aqua Feed, Coppens and Raanan can be found internationally, so my advice isn’t restricted to only Nigeria.
What Feed Dimension to Give Your Catfishes
Like I mentioned earlier, there are numerous fish feed sizes, whether or not you go for floating or sinking feed; sinking feed is normally larger, and longer, than floating feed.
From my expertise, listed here are the completely different sizes I’m at the moment conscious of:
1.5mm, 1.8mm, 2mm, 3mm, 4mm, 6mm, 8mm, 10mm, and many others.
The larger you fishes, the larger the feed dimension they will choose.
Right here’s what I like to recommend should you simply stocked your ponds, in case your fishes fall into the next classes:
- Fingerlings (3 to 4 grams): 1.5mm feed dimension
- Put up-fingerlings (4 – 6 grams): 1.8mm feed dimension
- Juvenile (6 – 10 grams): 2mm feed dimension
- Put up-juvenile (10 – 50 grams): 2mm feed dimension
As your fishes develop, the scale of feed they will choose will improve. Right here’s the feed dimension I like to recommend for larger fishes, based mostly on their dimension/weight, should you’re to offer them floating feed:
- 10 – 50 grams: 2mm feed dimension
- 50 – 150 grams: 3mm feed dimension
- 150 – 400 grams: 4mm feed dimension
All issues being equal, your fishes ought to be round 200 – 300 grams in 2 months with floating feed alone, if they’re being fed correctly; after then, you possibly can change to sinking feed and provides them the next feed sizes:
200 – 300 grams: 2mm feed dimension
300 to 600 grams: 4mm feed dimension
600 grams to 1kg+: 6mm feed size
In case your fishes exceed 1kg in weight, and also you’re capable of get larger feed sizes, then you possibly can contemplate giving them 8mm, and even later 10mm, feed sizes. 3 to 4kg fishes eat 6mm sinking feed simply superb, although, so don’t fear an excessive amount of should you can’t discover larger feed sizes.

How Typically Ought to You Feed Your Fishes?
How usually you feed your fishes will differ relying on rather a lot of components, however for the outcomes I get – an common of 1.5kg to 2kg fish dimension in 6 months – right here’s what I like to recommend:
- Fingerlings (3 to 4 grams): twice each day
- Put up-fingerlings (4 – 6 grams): a few times each day
- Juvenile (6 – 10 grams): a few times each day
- Put up-juvenile (10 grams and above): as soon as each day
- Something above post-juvenile: as soon as each day
All issues being equal, I feed my fishes each day till they attain the 6 months mark after I promote them; that is completely important if you’d like optimum outcomes.
Varieties of Catfish Feeding
There are two feeding varieties I take advantage of for my fishes:
Broadcast Feeding: This principally includes me going spherical my ponds and spreading floating feed all over the pond to make sure all of the fishes within the pond can eat.
I take advantage of this for my fishes if they’re within the fingerlings to post-juvenile stage, and I do that as a result of they simply bought launched into a big physique of water, usually from someplace considerably smaller, and never all of the fishes can come to the identical spot to eat.
By spreading the floating (or extruding) fish throughout the pond, I’m guaranteeing all of them get to eat.
As soon as my fishes grow to be extra mature, usually that is within the post-juvenile stage or round 30 – 50 grams, I immediately change to identify feeding.
Spot Feeding: Spot feeding is much less time-consuming and simpler, since it’s much less hectic and I can fastidiously monitor how my fishes are consuming.
Spot feeding is principally me feeding my fishes in a single spot.
I strive getting my fishes to eat in a single spot as soon as they attain 30 – 50 grams, or after 2 – 3 weeks of stocking them from juvenile stage.
At first, if they’re used to consuming utilizing the published model, most of the fishes received’t come to a specific spot to eat; nevertheless, by ONLY feeding them on that spot for a number of days, they’ll be conditioned to return to that spot and eat.
