I need to assume that your catfish are juveniles. If sure, they are going to be round 6-8weeks of age. At this age, 2mm of imported feeds is advisable.
As they continue to grow and from expertise, I’ve come to conclude with the sizes that correspond to their age particularly if they’re from good supply and are responding properly to their feeds.
As an illustration: 2mm at 2months, 3mm at 3months, and 4mm at 4months and so on.
Nevertheless, the kind of feed must also be thought-about, as an example the dimensions of 8mm coppens is identical as the dimensions of 6mm of Indonesia feeds.
So put this into consideration and inform your marketing consultant earlier than altering from one dimension of feed to one other.
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 greater, and longer, than floating feed.
From my expertise, listed here are the completely different sizes I’m at present conscious of:
1.5mm, 1.8mm, 2mm, 3mm, 4mm, 6mm, 8mm, 10mm, and so on.
The greater you fishes, the larger the feed dimension they’ll decide.
Right here’s what I like to recommend if you happen to 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 catfishes develop, the dimensions of feefeedd they’ll decide will enhance. Right here’s the feed dimension I like to recommend for greater fishes, based mostly on their dimension/weight, if you happen to’re to give 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 needs to be round 200 – 300 grams in 2 months with floating feed alone, if they’re being fed correctly; after then, you’ll be able to swap to sinking feed and give 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 ready to get greater feed sizes, then you’ll be able to think about giving them 8mm, and even later 10mm, feed sizes. 3 to 4kg fishes eat 6mm sinking feed simply high quality, although, so don’t fear an excessive amount of if you happen to can’t discover greater feed sizes.
How Typically Ought to You Feed Your Catfishes?
How usually you feed your fishes will differ relying on 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 every day
- Put up-fingerlings (4 – 6 grams): a couple of times every day
- Juvenile (6 – 10 grams): a couple of times every day
- Put up-juvenile (10 grams and above): as soon as every day
- Something above post-juvenile: as soon as every day
All issues being equal, I feed my fishes every day till they attain the 6 months mark once I promote them; that is completely important if you’d like optimum outcomes.
Varieties of Catfish Feeding
There are two feeding sorts I exploit for my fishes:
Broadcast Feeding: This mainly includes me going spherical my ponds and spreading floating feed everywhere in the pond to guarantee all of the fishes within the pond can eat.
I exploit this for my fishes if they’re within the fingerlings to post-juvenile stage, and I do that as a result of they only bought launched into a massive 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 develop into extra mature, usually that is within the post-juvenile stage or round 30 – 50 grams, I immediately swap to spot feeding.
Spot Feeding: Spot feeding is much less time-consuming and simpler, since it’s much less anxious and I can fastidiously monitor how my fishes are consuming.
Spot feeding is mainly 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 printed type, most of the fishes received’t come to a specific spot to eat; nevertheless, by ONLY feeding them on that spot for a few days, they’ll be conditioned to come to that spot and eat.

Feeding at the suitable time(s) every day (Feeding Frequency).
Feeding Frequency has a function to play within the utilization of the feeds by the fish.
Feeding frequency is the quantity of occasions fish in a pond are fed every day.
The frequency is essential so as to scale back hunger and have a uniform development charge.
Smaller sized fish needs to be fed extra often as their abdomen is simply too small to maintain meals they might require for the entire day, while fish from 400 g and above might be fed as soon as a day.
For instance, the 1,000 fish above requiring 4.5 kg every day ration needs to be fed twice every day.
Which means the 4.5 kg of feed needs to be divided into 2.25 kg to be fed within the Morning and Night.
How to simply calculate Feed ration, frequency and dimension
