You hit it right on the spot. Has this Pangasius been properly studied if they would not become invasive species in our bodies of water?

On the other hand, the impact would not be like of that Janitor fish becuase people will be catching and eating this fish unlike janitor fish.

Sa South Vietnam pag tag-ulan sa buwan ng Setyembre -Nobyembre nasa 0 – 3 ppt ang salinity ng tubig sa mga sapa at palaisdaan. Pagdating ng December at January tumataas na ang salinity mula 6 hangang 10 ppt. Karaniwang harvest ng Pangasius ay April na at ang salinity ay nasa 15 na.

Although, by nature kung nasa wild sila ang Pangasisus ay umaakyat na mula sa bukana pataas sa Mekong Delta. Pero sa mga cage enclosures at ponds nabubuhay pa rin sila kahit ang salinity ay mataas na.

Bakit di mo subukan?

I am interested in pangasius growing and contract broiler business.

Appreciat if you can assist me please.

Brackishwater has a salinity of over 20ppt.

The paper did not say if Pangasius will grow at this salinity because their experiment was limited to 48 hours salinity exposure.

I thought you already have a pangasius hatchery because you have advertised to sell fingerlingws.
Pangasius maybe easier to grow than tilapia and hito, but its hatchery is more complicated. You will need to construct hatchery facilities specific for this fish.

There is an article on the breeding of Pangasius in this site. Go over it and it will give you an idea how it goes.

1st reminder – can any one help me find correct person for the replies to my questions and suggestions. thanks and regards,

Sub: Commercial culture-farming of Pangasius Tra and Basa at our farms in Sindh Pakistan .

Dear Sir(s),

After successful culturing the Indian and Chinese carps successfully for many years at our farm we would like to go into commercial culture of Pangasius, the more we read about it the more we are obsessed by this fish – the main advantage in its culture is the quantity stocked per acre, its growth rate and that if cultured properly one can take two crops per year?

For your information besides commercial carp culture, we in collaboration with PARC Pakistan Agriculture Research Council have carried out many experiments of fish prawn culture and are now planning to establish a pilot scale fresh water prawn hatchery for malcolmsonii. (Photographs attached)

Please note besides our grow out area we have separate portions of different acreage which could be year-marked for Pangas culture after some modifications, other portions A and B could be used at a later date as well. We can easily manage lot of trash fish which is available near or adjacent to our farm from canal networks.

Before proceeding further we need a lot of information guidance from (NACA) your side and other Pangus farmers – experts enabling us to judge the feasibility of medium – large-scale commercial farming of Pangasius Tra and / or Basa in Pakistan initially for the local market and later on for export.

Major problem in Pakistan we (1) neither have Pangas seed nor (2) factory made high protein floating feed ???.

We can resolve the above by initially importing good quality fast growing Pangas fry form either Vietnam or Bangladesh ? And secondly try to prepare high protein 25-35% feed at our farm or at one of the feed mills (catering for our large poultry industry) as most of the other ingredients are available – making of floating pellets could be dealt with later?

Our questions are as follows: -

1. Which type of Pangas has the fastest growth rate and proved to be most successful amongst farmers?

2. Like to import 1-2,00,000 1.5” – 3” fry – Give me some reliable addresses of Pangas seed-fry suppliers in Vietnam and Bangladesh so that we could get price idea of – farm gate, fob and cnf Karachi airport – qty, packing, size of fry per bag, how many bags in a carton etc. duration of oxygen? mortality etc.

3. What is the growth rate if say 15,000 – 20,000 fingerlings are stocked per acre or per Ha (please clarify) can it attain a size of 1-1.5kg in a culture cycle of say 8 months – 10 months? Is there a standard feasibility available?

4. Pangas being air breathers – what is the requirement of water exchange in % or top ups every 3rd day, weekly etc.

5. Floating feed is recommended meaning the fish will only consume floating feed-pallets? Does it consume feed which is sinking or feed at the bottom of the pond?

6. Can we after 2-3 years prepare our own brood and breed them locally by stripping / artificial reproduction for seed – it must be similar to common carp – Rahu or grass carp etc.-what is the qty of eggs per kg of female?

Would appreciate if you could incorporate it in your next publication and / or post this letter in one of your forums (with intimation to us) enabling Pangas farmers – experts and seed suppliers to initially guide me properly for a successful initial start, thanking you in advance.
