BLACK SOLDIER FLY LARVAE HARVESTER

Jun 1, 2016

Lot’s of ways to do BSF. Here’s a few that we do in the Philippines for year round grubs Find compatible diameters Combine upper big with lower little (your upper little can combine with another lower still smaller still) I’ve used 120 Liter/80 Liter, 80 liter/45 liter successfully but check for compatibility before you buy! Make sure your rack holds everything if you want self harvesting Use a filler that is available that you are comfortable with- cement with perlite, body filler, epoxy etc. Make sure your 35º evacuation ramp is sealed, drainage of lechate is adequately sloped Rack system with room for lechate collection Don’t forget the nursery! Females lay eggs in corrugated material on underside of lid. Leave holes for entrance of pregnant females. Let 1-2% hatch under ideal conditions to assure perpetual propagation. We use a small pupating chamber for the new generation to come on line Use a simple method to start if you can’t copy the above...

THE TERROR OF THE DEEP..!

THE TERROR OF THE DEEP..!

Apr 24, 2016

Many of you, I’m sure, have possibly never seen a Dragonfly Nymph and know very little if anything about them. They are actually the terror of the deep when it comes to small fish and if you do not protect you fish tanks and other receptacles which are susceptible to being cruised by the adult Dragonfly, your fry and small fish will be their feeding grounds and you will never know what happened to them.  They, among other critters, are the reason that you never bring in plants you have gathered from the wild such as creeks and ponds. This video should give you a little incite into what they are capable of /li> A dragonfly is an insect characterized by large multifaceted eyes, two pairs of strong transparent wings, and an elongated body. Dragonflies are similar to damselflies, but the adults can be differentiated by the fact that the wings of most dragonflies are held away from, and perpendicular to, the body when at rest. Dragonflies possess six legs (like any other insect), but most of them cannot walk well. Dragonflies are some of the fastest flying insects in the world. In general, large dragonflies like the hawkers have a maximum speed of 10–15 metres per second (22–34 mph) with average cruising speed of about 4.5 metres per second (10 mph). Dragonflies are valuable predators that eat mosquitos, and other small insects like flies, bees, ants, and very rarely butterflies. They are usually found around lakes, ponds, streams and wetlands because their larvae, known as “nymphs”, are aquatic.A Dragonflies life span covers three stages; the egg, the nymph, and the adult dragonfly. Most of their life is lived out in the nymph stage. Male and a female dragonflies mate while they are flying, then the female will lay her eggs on a plant in the water, or she will just drop them into the water. Once the eggs hatch, the dragonflies life begins as a nymph. A nymph looks like a little alien creature. Dragonfly nymphs live in the water while they grow and develop into dragonflies. Dragonfly nymphs live in ponds or marshy areas because the waters are calmer than in a...

BLOOD WORMS

BLOOD WORMS

Mar 16, 2016

Bloodworms are larvae of the mosquito-like midge family Chironomidae. Almost all chironomids have aquatic larval and pupal stages. They have a world-wide distribution and occur in a wide range of aquatic habitats from fast flowing to completely still and stagnant, and in waters that range from fresh to saline. There may be more than 5000 species but only a small number have been formally identified. There is little difficulty in recognizing the larvae; they are small, distinctly segmented worm-like animals. Although, they are not a true worm due to their exoskeleton and small clawed legs. Their color is variable; some common ones are white, green, yellow, or deep red. The latter is due to the presence of the red pigment, erythrocruorin in the blood of the larvae, the presence of which is of respiratory advantage in waters with low levels of dissolved oxygen (stagnant pools). Some are also transparent and are commonly known as glassworms. However, only those that contain erythrocruorin are red and hence the common name “bloodworm”. In some countries they are also known as red mosquito larvae. Food value to fish Chironomid larvae and pupae have a relatively high protein content with high digestibility, and constitute one of the staple food items of many fishes in their natural environment. Chemical analysis (% of dry weight) shows that bloodworms contain 71–93.6% moisture, 47.7–62.5% protein, 4.9–28.6% fat, 2.3–21% ash, and 4–23% carbohydrates. They are also a good source of iron for the fish since they contain hemoglobin. Bloodworms are a commonly used as a live or frozen food source for aquarium fish culture. Almost all fishes will greedily devour them when they are offered. Research has found that most fishes when provided with bloodworms as a supplementary food item have better growth and spawning rates. Frozen bloodworms could be used as a substitute for live tubificids as they have a comparable protein level. Life cycle Chironomidae go through a complete metamorphosis in their life cycle, egg, larva, pupa, and winged adult midge. Each stage having different characteristics. After mating in flight the female releases the eggs while skimming the water surface. The eggs sink to the bottom where, under tropical conditions, they hatch...

AQUAPONIC SYSTEM DEFICIENCIES..!

AQUAPONIC SYSTEM DEFICIENCIES..!

Jan 10, 2016

Aquaponic Deficiencies- Get past the yellow and see more GREEN. Since the obvious goal of gardening, whether for pleasure of for profit, is to produce a quality product within the least amount of space possible and only a minimal amount of work; then it only stands to reason that we should offer our garden the best possible chance for success.  In organic gardening we must be careful of our choices, but in Aquaponics even more so.  We are not only striving for these goals, but creating an miniature ecosystem wherein we have a secondary means of product  – FISH!  In this carefully designed system we limit ourselves to not only organic standards, but we must also safely manage the health of our fish. Many aquaponic gardeners struggle with maintaining the necessary critical levels of highly usable forms of Calcium, Phosphorus, and Iron since these are either minute or   missing entirely in the nutrient rich effluent.  How much and how often the addition of these nutrients is necessary is a constant  topic.  Without them you will most likely be missing out on how productive your aquaponic garden can be, but the answer to the question is not set in stone.  Since the need for these nutrients depends on what you are growing, your necessary inputs may likely change thru the season.  In any case, we still must adjust standard garden practices for safe and fish friendly products to correct the deficiencies. In the end if we can provide natural and effective means of these elements, then the outcome is always sweet success.   So the question then becomes, What is safe for aquaponics? For both the beginner and the seasoned aquaponic gardener… these items should be in your arsenal. Calcium – Blossom end rot is the most common deficiency mentioned when it comes to Calcium– and it can occur in tomatoes as well as other fruits and vegetables, but limited calcium also plays a role in the general growth and development of the plant as well as the ability of fruit to form correctly and maintain a stable cellular structure after harvest. -Coral Calcium in Liquid or Powdered form tops the list for easily absorbed...

NEWS FROM DOWNUNDER…!

NEWS FROM DOWNUNDER…!

Jan 3, 2016

I received this article from a Mate Down under and even though it doesn’t tell you how to do anything in particular in Aquaponics, it does  show that there is substantial interest in the technology world wide and not just in your back yard or for hobbyist. Aqauponics is slowly coming of age and headed toward commercialism at an ever increasing speed. Our thanks for this article submitted by Andrew Dezsery. Commercial Aquaponic Funding Secured …A First For Australian Sector Development Funding for training a commercial sector in integrated farming called Aquaponics will be underway in May 2011. Participants will be trained by aquaculture identity Andrew Dezsery M.Sc at various locations in South Australia and Victoria. FOR IMMEDIATE RELEASE The Land Down Under… (Press Release) -2011 – A successful provision of funds through the S.A. Government, Community Grants for Natural Resources Management to the Riverland Local Action Planning Committee Inc will allow their project, “Building farming skills in profitable water reuse” to begin in May. A well known Northern District aquaponic research farm run by Andrew Dezsery M.Sc and Gavin Smith will be a hub in its practical demonstration. The development of practical skills amongst rural landholders in the use of the ‘Aquaponic’ production system is a focus of this project.  Aquaponics is a joined system of freshwater fish production and hydroponic vegetable production. The cycling of wastes between fish production and vegetable production ensures high nutrient reuse efficiencies and a natural bio mimicking form of water filtration. The project will provide a training service in conjunction with the use of learned farming skills at an existing production facility in the Northern Adelaide Plains Gawler River Region. Several integrated aquaculture projects over the last 6 yrs by these forward thinking research innovators to save communities like the dying Riverland region have been developed and presented by the #1Aquaponic research farm and its sister business Aquaculture Advantage. This site has been visited by Australian and international students, booked luncheon edu-tours and numerous government funded agencies since 2006 leaving its visitors in awe at the cutting edge developments this tech savvy farm offers. Visitors are excited at the possibilities of further local job creation, sustainability and minimal water requirement in a dry state and all with no chemical fertilizer, pesticide or herbicides use producing two crops with one drop of water.

WHICH GROW BED IS BEST..?

WHICH GROW BED IS BEST..?

Nov 30, 2015

Grow beds are an intrical part of Aquaponics because that’s the container where the vegetables grow. Growbeds come in many different forms and configurations, but the principles remain the same for each type regardless of whether you built it yourself using wood, fiberglass, concrete blocks or plastic 55 gal drums cut in half or even plastic storage containers from the local family store. They can be any width or depth desired by the Aquaponist in accordance with what they are growing. 1) A Raft system grow bed contains nothing but water. The width can be whatever is desired but the depth of the water should be a minimum of 12″ to allow for growth of the roots. 2) Food grade plastic barrels cut in half, either vertically or horizontally 3) Commercially manufactured grow bed are available from a number of manufacturers Grow beds are equipped with inlet and outlet fittings to attach PVC or rubber tubing to. This allows for the nutrient rich water to be pumped from the fish to the grow beds and then back to the F/T (fish tank). One of the fittings that is commonly use is called a Bell siphon. This apparatus can be built from materials purchased from the local home building supply company. Its function is very simple. It is the outlet for the grow bed and functions as follows. It allows nutrient-rich water to be pumped from the F/T into the grow bed to the Aquaponist desired depth. Once the desired depth is reached, a siphon is created and the water in the grow bed is then siphoned out via the Bell siphon until the grow bed is empty of all water, then the process is started all over. The amount of time it takes to fill the grow beds to the desired depth is determined by the GPH (gallons per hour) and HR (head rate – the GPH the pump will pump at a given height) rating of the pump being used. Naturally the more GPH the pump will pump and the stronger the HR, the faster the grow bed will be filled. Growbeds contain media in which the plants are placed. The media is...
