2.0 FISH SEED PROPAGATION What is fish seed? Fish seeds are young fish (Larvae, fry and fingerlings) that grow to become table or parent fishes. What is Seed Propagation? This is the science of assisting parent fish to multiply and have descendants. Method of fish Seed Propagation Fish seed propagation could be by:  Natural spawning  Induced spawning without hormone treatment  Hormone induced natural spawning  Artificial spawning) making parent fish to produce off spring willingly in a controlled environment). Why Artificial Spawning?  Fish seed collection from the wild is seasonal and unpredictable.  By manipulation of hormonal and environmental factors, fish seeds can be produced un-interrupted all year round.  The disease and genetic history of wild fish are unknown and as such wild seed are less tolerant to changing physical and chemical conditions in ponds than the hatchery-bred.  Health history and genetic history of hatchery-bred fish could be traced ...

FISH BREEDING TECHNIQUES AND HATCHERY MANAGEMENT 1.0 INTRODUCTION Aquaculture sector is the only division of fisheries where its output can easily be determined depending on the type of production system used. In Nigeria today, aquaculture has provided economic, social and environmental benefits by strengthening relationship between the youth and the Government, decreasing dependence on Government for white collar job and also provides security to our economy and culture. However, the increase in world production and change in diet demand a large, more reliable and expensive supply of animal protein and fish products. According to FAO report in 2002, Nigeria requires two million metric tones of fish annually for consumption but all fishery activity in Nigeria including industrial fishery, artisanal fishing and aquaculture can only produce 2 percent (2%) of this requirement. The aquaculture industry in spite of recorded successes has various hindering problems which inc...

Many fish feed companies keep a good listening ear to suggestions, feedbacks that my company furnishes them with including pricing. We can't say we are alone but God is good always n that informs some allowing us to check out there feeds  Let's start with foreign feeds. Biomars, coppens and Ziegler fishfeed are feeds that we experimented on during this period. Specifically we tested them on our  fish both in earthern ponds n concrete tanks. The results were quite surprising because we understood that there is a difference between "best before " $ "expired "  Most imported feeds are carrying best before doesn't mean that after d date feed is not fit for fish but it simply means it's quality has reduced. Now here is d twist. Best before in concrete/tarpaulin tank fish culture. We found out that after the best before date up-to 6minths the feeds still had good aroma, colour and fish still ate it very well and developed. The difference was not th...

Starting from 1.The pulverizer Materials like maize,,,soy products,,,,or any other materials that isn't easily digested by monogastric are to be pulverized using mesh size of about 1mm,,,most feed mill won't use such mesh as it tends to slow down the production compared to bigger size mesh,,,, Improperly pulverized maize or soya meal,toasted soya,,ful fat soya,wheat,, are mostly wasted when included in the ratio as about 50% or more won't be digested by catfish But each feed ingredient  also has its digestibility % Each has distinct effects on the quality of the end product Yes,,, feed material digestibility % can be increased when properly processed,,,for example finely pulverized maize that is steamed before pellets won't have digestibility % like crushed maize  At the mixing stage... All materials most be mixed evenly so as to have same feed taste,,quality and colour in a certain production Feed additives are one of the major secret that's giving most i...

PRODUCTION OF QUALITY FISH FEED. Especially. The most important thing in feed production is understanding the nature of each feed materials as regards the physiological effects on monogastric(single stomach ) animals like catfish If we all have/use same feed formula we could all end up arriving at very different feed quality: Let me kindly explain using the basic machines mostly used in Nigeria especially for sinking feeds  Aims that must be targeted in feed are 1.Digestibility (fcr) 2.Palatable  Items that are not too necessary for proper pulverizing are gnc,,garri,,indomie/spaghetti,,,dried fish,,,among others  So kindly request for finely pulverize materials mostly cellulose materials so as your fishes to get optimal digestion  The most used fish feed equipment are sold by capsfeed or locally fabricated duplicating capsfeed imported machines To produce effectively,,,the machines that should be available are 1.Pulverizer 2.mixer 3.Steam boiler 4.pe...
