Fisheries & Aquaculture - Aquaculture Aquaculture, probably the fastest growing food-producing sector, now accounts for nearly 50 percent of the world's food fish. The need to exchange reliable information on all related subjects is becoming a key issue for the responsible management of aquaculture.In order to provide easily-accessible and up-to-date information, the FAO Fisheries and Aquaculture Department has developed specific pages on aquaculture where users can consult relevant material on aquaculture at international, regional and national level. The Global Synthesis of aquaculture development status and trends, andsix Regional Reviews of aquaculture development, status and trends. Fact Sheets Aquaculture Fact Sheets contain a synthesis of detailed information on specific subjects and include related statistics, graphics (GIS maps, images, figures, etc.) and profiles. The Fact Sheets cover the following information domains: Statistical information This includes statistics and databases related to aquaculture.

The Ultimate Guide To Living Green Walls | Ambius | Greener on the Inside Living green walls. You may have heard of them and thought they were no more than the latest design fad. However in truth, the concept dates back to the 1930′s and they are science fiction made fact! No longer just of interest to architectural companies trying to win design awards, they are gaining attention from businesses of all sizes looking to improve their green credentials. Before you know it, you’ll be boring your friends, colleagues and boss as you preach like one of the newly converted! Living green walls are panels of plants, grown vertically using hydroponics, on structures that can be either free-standing or attached to walls. When was the living green wall invented? The idea for living green walls was first patented by Stanley Hart White in 1938, however it is Patrick Blanc’s name that resounds through the industry. Now known as green facades, plants have probably been growing on buildings since the first stone was laid. How do living green walls improve air quality? The U.S.
Facts About Abalone Facts About Abalone Classification In the animal kingdom, abalone belong to the phylum Mollusca, a group which includes clams, scallops, sea slugs, octopuses and squid. The abalone join other snails, whelks and sea slugs in the class Gastropoda. Anatomy The most conspicuous part of any abalone is the shell, with its row of respiratory pores. Anatomy of an Abalone with Shell Removed The internal organs are arranged around the foot and under the shell. The gill chamber is next to the mouth and under the respiratory pores.

DWC Hydroponics In this instructable video I will go over my "Deep Water Culture" hydroponic system and show how I modified the process to deal with all stages of plant growth including seed starting. DWC hydroponics is a very efficient system while being extremely beginner friendly. Parts cost is quite low and the system easily scales in size. This is a very basic overview of DWC hydroponics but is a system that can easily be expanded or reduced to suit your growing needs. Personally I wanted a system that would provide fresh greens all winter long while requiring very little human intervention. As it currently stands this system has fully automatic lighting and irrigation (mechanical timer based), the only aspect I need to be involved with is the initial seed planting and water changes. In the video below I will go thru all aspects of my system which should answer all of the major questions regarding DWC hydroponic growing. Enjoy, and many thanks!

Kunyit Turmeric or Kunyit in Malay is a rhizomatous herbaceous perennial plant of the ginger family. This plant is use as herb in Malay medicine and cooking, leaves and rhizome are use to add flavour to dishes and cure sickness. I am trying out this plants, normally it doesn't grow in water logged soil. Maybe due to my pump OFF condition at night make this herb grow able. These Turmeric are on my home kit, in my main set up I dedicate I growbed for it. So far the result of this backyard test is encouraging. Close up above showing young shots emerging from the bed, with this its an indication that its multiplying and the rhizome survive the growbed condition. More shoots emerging from growbed. Above Turmeric in my main setup growbed, these about 1 months after replanting. There are few problem I am experiencing, heat damage to the leaves and Bugs. Above leaves show sign of heat damage. This leaf show partially eaten by bugs, mostly caterpillars. Turmeric root forming below.
Aquaponics Is Growing Farms in the Most Unlikely Places Aquaponic farm at University of Hawaii, via Kanu Hawaii/Flickr The world is growing and growing ever more hungry, and there isn’t a single, perfect way to get more food. The changing climate and a projected water crisis cloud the future of agriculture, but the sting of food shortages is already with us, catalyzing riots and political unrest in places like Turkey, Syria and Egypt. But countries from Bangladesh to Yemen, and cities from Berlin to Tucson, are employing an ancient farming technique to the 21st century—aquaponics is growing orchards in the desert and yielding harvests in the city. For the water-strapped, aquaponics can look like a miracle cure. Faris Farrag studied under Rakocy at the University of the Virgin Islands, and brought the technique back home to Egypt, where he has started the country’s first commercial aquaponics farm. It’s not nearly time to leave the fields to fallow and move to an all-fish tank system, however. And aquaponics isn’t cheap.
Aquaponics A small, portable aquaponics system. The term aquaponics is a blend of the terms aquaculture and hydroponic agriculture. Aquaponics (/ˈækwəˈpɒnɪks/) refers to any system that combines conventional aquaculture (raising aquatic animals such as snails, fish, crayfish or prawns in tanks) with hydroponics (cultivating plants in water) in a symbiotic environment. In normal aquaculture, excretions from the animals being raised can accumulate in the water, increasing toxicity. As existing hydroponic and aquaculture farming techniques form the basis for all aquaponic systems, the size, complexity, and types of foods grown in an aquaponic system can vary as much as any system found in either distinct farming discipline. History Woodcut from the 13th century Chinese agricultural manual Wang Zhen's Book on Farming (王禎農書) showing rice grown in a floating raft planter system (架田, lit "framed paddy") in a pond Aquaponics has ancient roots, although there is some debate on its first occurrence:
Aquaponic fish Lemnoideae Duckweeds, or water lens, are flowering aquatic plants which float on or just beneath the surface of still or slow-moving bodies of fresh water and wetlands. Also known as "bayroot", they arose from within the arum or aroid family (Araceae), and therefore, often are classified as the subfamily Lemnoideae within the Araceae. Classifications created prior to the end of the twentieth century classify them as a separate family, Lemnaceae. These plants are very simple, lacking an obvious stem or leaves. The greater part of each plant is a small organized "thallus" or "frond" structure only a few cells thick, often with air pockets (aerenchyma) that allow it to float on or just under the water surface. Depending on the species each plant may have no root or may have one or more simple rootlets. Reproduction is mostly by asexual budding, which occurs from a meristem enclosed at the base of the frond. Duckweed in various environments Taxonomy Research In July 2008 the U.S.
Aquaponics JAN 2012 Aquaponics disaster and update After starting the Aquaponics in Sept 2011 the plants grew fantastic before a really bad Aphid attack took over. I tried everything including a non chemical method of Garlic (boiled) mixed with a little Olive oil and spayed all the plants. The results were disastrous killing most of the plants and most of my fish. The system as of Jan 2012 doing well Newly added fish stock Replanted System in Dec 2011 Dec 2011 just before it all collapsed System planted Sept 2011 Cool Time Capture video AUG 2011 Time for an update and major makeover of the aquaponics system. Anyway time for a clear out, one problem i have created by over planting to many big root plants like the bell pepper (capsicum) tomatoes, celery is the roots have clogged up the system to the point that the flush cycle has failed, so now armed with a bucket and kitchen colander i will remove all the plants then the stones, clean and replace and retest flush cycle. A clogged up system
Aquaculture Water Use, the USGS Water Science School As the label in the grocery store says, "Farm Raised Tilapia Fillets" are for sale. Yes, fish farming is big business and many people eat farm-raised fish and other seafoods. If you've never hear of fish farming, I must disappoint you and say that, no, fish are not farmed in the same manner as corn on stalks, but rather in large ponds. Fish farming is only one aspect of aquaculture. Aquaculture withdrawals for the Nation, 2005 During 2005, the estimated rate of freshwater withdrawn for aquaculture was 8,780 Mgal/d, or 9,840 thousand acre-feet per year, with surface water being the source of about 78 percent of the withdrawals. Aquaculture withdrawals, by State, 2005 Trout fingerlings in hatchery on Pyramid Lake Indian Reservation, Washoe County, Nevada.Credit: Ron Nichols, USDA NRCS. Idaho and North Carolina used the most water for aquaculture, about 40 percent of the total and about 50 percent of the surface-water withdrawals for aquaculture. Aquaculture water use, 2000
