The common housefly could be a bigfactor in easing the strain on natural marine resources, if the Drew brothers have their way.

Maggot meal is obtained by harvesting fly larvae fed on organic waste just before the insects turn into pupae. To make one ton of the meal, about five tons of maggots are required.The larvae are dried and then processed into a fine rich brown powder, to be sold to farmers in 50-kilogramme bags.In terms of nutrient value the product matches that of fishmeal and is superior to soya.Research and developmentThe fly farm and production plant is based in Stellenbosch and for the moment is producing only for research and development purposes, confirms Jason Drew.The facility produces two tons of meal a week. Research is conducted with the help of the University of Stellenbosch‘s Animal Nutritional Department.“We plan to start up a full scale production plant in 2013, which will produce 28 tons per day of the dry product,” says Drew.The company intends to open plants in South Africa and Germany, the latter country because it is one of the world’s leading green nations.According to Drew, the demand for protein feed is almost limitless, and one of the biggest chicken producers in Germany is already showing keen interest.His only concern is whether AgriProtein will be able to keep up with the projected demand of over 2 000 tons per month.Should other countries show interest, the Drew brothers will consider rolling out the technology to them as well.So far, AgriProtein’s research has shown that larvae protein produces better weight gain and lower gizzard erosion scores than fishmeal. Gizzard erosion is a dietary deficiency disease affecting younger birds.Nutrient recyclingAt the heart of AgriProtein’s approach is a relatively new concept: nutrient recycling.Increases in global food demand and pressing environmental challenges have caused prices of both fishmeal and soya feeds to soar in recent years. Fishmeal, for example, has on average almost tripled in price since 2002, according to the IndexMundi data portal.Using organic waste to create a new source of protein – such as animal protein feed – is one way in which we can save the world’s declining fish resources, believes Drew.At the AgriProtein plant the flies are fed waste from abattoirs. This natural way of disposing of the waste also helps the suppliers to cut down on their costs. To ensure success of the venture, the company runs two programmes, for breeding and production.Under natural conditions one female fly can lay about 750 eggs a week and the larva increases in weight by over 400 times in just a few days.Maggots are harvested just before the pupal stage, or after about 72 hours. They are then dried, milled and packed. Because birds and fish eat larvae in the wild, the magmeal is easily digested.AgriProtein uses three types of flies: the common housefly (Musca domestica); the black soldier fly (Hermetia illucens) and the blow fly (Calliphoridae family), each of which prefers to break down a specific type of organic waste.The end product contains nine essential amino acids, according to the AgriProtein website.And that hint of fishmeal which is sometimes so detectable in battery-reared chickens will also be a thing of the past as maggot meal has a completely neutral taste and odour, Drew confirms.Amazing creaturesLike other insects the fly goes through three phases to reach adulthood: egg, larva, pupa and then adult.One of the most fascinating aspects of these creatures is the ammonia which is produced by fly larvae, a natural secretion used by the creatures to kill bacteria.In the AgriProtein plant the strong smell of ammonia is a by-product of the production process but one which the Drew brothers still plan to tap into as well.“We are looking at ways in which to harvest the ammoniated air to make a natural bleach,” says Drew.

This Geocache of the Week is also a Travel Bug Motel, and while the cache itself is plain—spoiler alert, it’s an ammo can—you’ll probably be grinning wildly by the time you reach it. It’s a Travel Bug Motel in more ways than one.That’s right, folks. The cache is tucked inside a cherry red VW Bug which, depending on the season and the whims of the property owner, alternately has flowers, tall grasses, or various other living things sticking out from its roof. (Speaking of the property owner: permission was granted for the placement of the cache!)What geocachers have to say:“A day off of work in the area and this cache made the list. another great cache nearby. what a cool ideal, hope they don’t try to move it. Gets a favorite point from us. TFTC.” –2CraziesMSN“This was another must do cache on this trip. psychoVW loves cars, especially Volkswagens, and especially Beetles, and especially abandoned cars. This one had everything! She slugged me, as usual, when we drove past this on the way to another cache. When we arrived here, Paycho guessed where the cache was and made the find. Nice camo! We took some pics, and I dropped off the VW Beetle trackable I had picked up that I had been saving specifically for this cache.” –Darth Leviosa“On our way to geocoin fest and this one popped up on our favorites filter. Very interesting area. Looks like somewhere out of a Hunter S Thompson novel. Picked up a couple trackables to take with us and dropped one off. Favorite point for taking us to the Boondocks.” –DublinMN“GZ produced a big bug, but I did not squash it! thanks for the swag … TFTC!” –November GhostPhotos: SharePrint RelatedSea Shells – TB Stop & Go GCNWBC GEOCACHE OF THE WEEK – February 6, 2012February 6, 2012In “Community”The Director’s Travel Bug Hotel (GC3MFAD) — Geocache of the WeekOctober 15, 2015In “Geocache of the Week”It’s Bigger on the Inside! — Who?: Regeneration (GC5ZFGA) — Geocache of the WeekJanuary 7, 2016In “Community” Continue to explore some of the coolest caches around the world.
