Tsukamoto Katsumi has devoted most of his long career to the study of the Japanese eel and its spawning behavior. Now, with overfishing and other pressures threatening populations of freshwater eel worldwide, Tsukamoto has joined forces with colleagues from China, South Korea, and Taiwan in a race to unlock the secrets of these mysterious—and famously tasty—migratory fish and rescue them from extinction.

Conservationists have long warned that bluefin tuna stocks are declining. While the development of aquaculture may offer an alternative, it doesn’t come without a few headaches of its own.

While the debate about deforestation due to palm oil rumbles on, new research has suggested that the release of methane from palm oil processing wastewater may also be a significant concern.

In the Palm Oil debate students need to be well informed to make an educated decision about where they stand on the issue. This includes thinking about the long term benefits and problems of Palm Oil. This includes critiquing competing factors that influence the design of services (ACARA, n.d). This article discusses the environmental cost of the manufacture of Palm Oil in regards to methane emissions.

Sea urchins appear to be the lowliest of marine creatures—the painfully prickly echinoderms sit at the bottom of the ocean, feeding on algae far beneath the sea’s majestic swimmers. But there’s one set of landlubbers that can’t get enough of the briny deep’s ugliest residents: Sushi eaters.
Green sea urchin populations have plummeted in North America, thanks in large part to rising demands for uni, a sweet, creamy dish made from sea urchin gonads. As food writer Barry Estabrook recently noted, uni’s popularity on sushi bars prompted nearly 3,000 commercial fishermen to take to Maine’s seas in the mid-1990s in search of the delicacy. Diners couldn’t get enough, business boomed, and Maine’s fishermen hauled in nearly 40 million pounds of sea urchin worth about $33 million in 1994 alone. Via Olive Ventures

The development of the environmentally conserving dike-pond system of integrated agriculture and aquaculture in the Zhujiang Delta of south China is traced to illustrate the impact of environmental changes on technological innovations. The technologies of dike building, land reclamation, pond fish culture, and crop cultivation on dikes, which were either independently developed or modified from ideas brought in by migrant farmers from northern China, represented farmers' efforts to adapt to the new characteristics of a changed environment as population pressure increased. The new technologies revealed the farmers' awareness of the need for environmental conservation. However, increased population pressure also necessitated more intensive use of the land, both in the highland and lowland regions, giving rise to inappropriate dike building and premature reclamation activities, which in turn brought about more frequent flooding in the delta region. Careless application of a new technology tended to have harmful effects on the environment. Political conditions in different periods of China's economic development have also caused changes in the dike-pond system which has to maintain high productivity and profitability. Recent advances in dike-pond system technology have focused on crop diversification and animal husbandry to match the three-dimensional characteristics of its ecological components. New agricultural technologies can be successful in China only if they can provide a balance between land use and conservation. Via Dorian Q Fuller

A remedy for reclamation of salt land that brings it back to agriculture within a year or two; also an effective agriculture-aquaculture rotation concept. Both have been tested and economically proved as feasible in Syria in mid 1990s. |
