FISH SEED PROPAGATION

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 and
improved.

Basic Tools used in Fish Seed Propagation
 Concrete tanks/Incubation trough
 Hormone, Needle and syringe
 Funnel incubators
 Plastic Jugar Jars
 Towel
 Razor blade

MAGGOTS; A HIGH PROTEIN FEED FOR POULTRY, FISHERIES

MAGGOTS; A HIGH PROTEIN FEED FOR POULTRY, FISHERIES Feed is the single most expensive factor in all livestock production and Maggots are affordable, green and sustainable high protein feed (65% protein) for fish, poultry birds Maggot feed is noted to reduce mortality by close to 100% and are also a perfect replacement for current orthodox protein product offering in the market, soybean and carnivorous fishmeal and thus make farmers investment attractive. It has good nutritional value, cheaper and less tedious to produce than other animal protein sources. It is also produced from wastes, which otherwise would constitute environmental nuisance. The production system thus serves the dual purpose of providing a nutrient-rich resource as well as a source of waste transformation and reduction It has been suggested that the good growth and nutrient utilization capacity of livestock fed maggot-based diets stem from the high biological value i.e. nutrient composition and digestibility, o...

Fish Feed formulating

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...
