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...

Feeding fish

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...
