Duckweed as a Primary Feedstock for Aquaculture. Summary: The technical literature shows that duckweeds (Lemnaceae) have a strong potential as primary feedstocks for production of livestock and fish.

Duckweed as a Primary Feedstock for Aquaculture

These plants grow rapidly and are high in protein and dietary minerals and low in fiber. They do not produce toxic alkaloids and are palatable to a wide variety of domestic animals and fish. Feeding trials show that they are suitable for animal production, and that the meat is tasty and nutritious for human consumption. Growth of Lemnaceae requires shallow ponds, but their culture reduces evaporation from the water surface and decreases growth of undesirable algae.

Introduction: Duckweeds are the smallest flowering plants. A delightful, nontechnical discussion of duckweeds, has recently appeared in Pacific Discovery (Armstrong, 1989), while an article in Smithsonian (Stewart, 1989) mentions their role in advanced biological sewage treatment. Biology of the Northern Crayfish (Orconectes virilis) Description Crayfish, of which our own Northern Crayfish (Orconectes virilis) is one of about 500 species worldwide, are crustaceans related to copepods, barnacles, crabs, shrimps, lobsters, etc.

Biology of the Northern Crayfish (Orconectes virilis)

(Class: Crustacea, Order: Decapoda, Family: Cambaridae, Genus: Orconectes, Species: virilis) The Northern Crayfish grows to a length of about 10-12 cm, not including the 2 pairs of long antennae or the large chelipeds (pron: "keel-i-peds"), the large claw or pincer bearing legs, that extend forward. The chelipeds often have a bluish tint, particularly in the males which have larger chelipeds and larger pincers than females. The head and thorax are covered by a shell-like carapace, usually brownish to rusty red in colour. There are four pairs of jointed walking legs called pereopods (pron: "pair_ee_oh_pods") also attached to the thorax. Pereopods. Raising crayfish in the north? - Homesteading Today.

Making a Hotbed in your Polytunnel. I have been intrigued by the idea of a hotbed for years, but the trigger for this project was reading Hot Beds by Jack First.

This book is a great little resource, packed full of information on how to make a hotbed, and what to grow in one once made. Having put up a decent sized polytunnel (hoop house) last Summer, I've been waiting for the right time to build a hotbed.
