IN BRIEF - Record number of salmon return to Russian River
Friday, November 23, 2012
A record number of Chinook and Coho salmon are moving up the Russian River to spawn, an indication of rich ocean conditions necessary for those fish to survive, fisheries biologists said.
It may also be an indication that the millions of dollars being spent on habitat restoration to keep those fish from extinction may also be working.
There have been 6,348 Chinook salmon photographed as of Wednesday 21 Nov. moving through the fish ladders at the Sonoma County Water Agency's dam at Forestville, which is inflated during low river flows to create a pool for the agency's water pumping system.
Scientists from WCS (Wildlife Conservation Society), University of Queensland, James Cook University, and Macquarie University have completed a massive study that will help communities and countries of the Western Indian Ocean measure and restore fish populations while identifying the best policies for achieving global sustainable and conservation targets.
The researchers utilized more than 25 years of data from fish surveys and research focusing on the effectiveness of fishing closures to generate predictive models of recovery that will help marine managers better assess the state of reef systems and their fish populations in the Western Indian Ocean. The findings use previous studies to predict the recovery time of depleted reefs to levels where fishing is sustainable or conservation objectives are reached.
The study titled "Modeling Reef Fish Biomass, Recovery Potential, and Management Priorities in the Western Indian Ocean" appears today in the online journal PLOS ONE. The authors are: Tim McClanahan of the Wildlife Conservation Society; Joseph M. Maina of the Wildlife Conservation Society, the University of Queensland, and Macquarie University; Nicholas A.J. Graham of James Cook University and the University of Queensland; and Kendall R. Jones of the University of Queensland.
BELMOPAN - Caribbean countries have a living bank of marine resources from which they collectively cash out hundreds of millions of dollars a year to support emerging national economies by providing good jobs, food and foreign exchange, among other benefits.
However, in order to remain active and competitive in the global marketplace, countries have had to find ways to surmount the challenges posed by stringent international standards, called sanitary and phytosanitary (SPS) measures, for food safety and for protection against diseases carried by animals and plants.
Under a European Union-funded SPS Measures Project, the ability of Caribbean countries to effectively address those challenges is being strengthened through initiatives such as specialised training for those gatekeepers who help to ensure the safety of both imported and exported foods.
The project has reached a new milestone as a group of professionals from CARIFORUM States — the 15-member Caribbean Community and the Dominican Republic — has just concluded the Sanitary and Phytosanitary Management Course.
Louisiana's spring inshore shrimp season will open statewide May 23 at 6 a.m., after action taken Thursday 5th of May 2016 by the Louisiana Wildlife and Fisheries Commission. It's the second straight year that the opening won't be staggered among the state's shrimp zones.
Before the vote, department biologist Jeff Marx presented to the commission data collected Sunday showing that shrimp in the Barataria, Timbalier and Terrebonne basins would reach harvestable size on or before March 16. Historically, the commission has aimed to open the season when biologists determined 50 percent or more of the brown shrimp would be 100-count or larger.
Marx and his biologists forecasted that line wouldn't be crossed until later in the rest of the state, and recommended a May 23 opening for the Mermentau, Calcasieu and Sabine basins and a May 25 opening for the Pontchartrain Basin.
PANAJI - Goa's performance in overall marine fish production was unimpressive with Goa having shared only 2% of the total marine fish landings in India in 2015, with a contribution of 68,561 tonnes. Compared to the landings in 2014, the marine fish landings in Goa reduced by around 55%.
The report further revealed that in Goa, the dominance of mackerel followed by oil sardine was noticed as similar to Karnataka. About 88.9% of total catch of the state was contributed by mechanized sector and mechanized purse seine played a significant role among all gears.
An Australian invention has the potential to rid the world's oceans of micro plastics. Eighty-five per cent of the plastics in the oceans are micro plastics, and the environmental effects are severe. Now the Australian creators of the 'Seabin' have found that their invention could solve the problem.
Vijayapura - In 2016, there is a fish drought, and consequently, the price of fish has been going up in the past two months. With the district in the grip of drought, the availability of fish in the Almatti dam and the backwaters has dropped.
Drought has affected the life of fisherman. While the price falls every summer, this season it has risen. Usually, from February to May, the water level is low in the Almatti dam, and there is plenty of fish available. But with low supply, the price has risen. The Almatti dam backwaters covering areas such as Almatti, Gani, Chimmalagi, Benal, Mujarekoppa and the dam front village of Araladinni are dotted with more than 1,000 baskets (small boats used for fishing) in a 30km radius. City-based fish merchants would arrive in droves to buy fish from local fisherman. Every day, 10 quintals of various types of fish were bought near Almatti dam and packed in ice boxes to be sent to Hyderabad and Solapur.
Yamanur Kale, a fisherman, said, "But for two months now, not more than one quintal of fish is available due to shortage of water in the dam. So now the rate of fish is INR 200 per kg."
The Australian government recently announced an unusual initiative to eradicate a long-standing animal pest problem.
To rid their streams and rivers of invasive European carp crowding out native freshwater species, officials plan to begin introducing a strain of the herpes virus -- Cyprinid herpesvirus 3 (CyHV-3), or "carp herpes" -- into fish populations.
In a statement released May 1, Australian Department of Agriculture and Water Resources (DAWR) officials described their National Carp Control Plan, which will be developed over the next two and a half years at a cost of approximately AUD 15 million (about USD 11.2 million) and potentially deployed by 2018.
Authorities are still scratching their heads over what killed 35 tonnes of fish all of a sudden, which washed up in a frightful sight in south China this week.
The fish floated to the surface of the Hongcheng lake, located in the Hainan island, China's southernmost point. The government is investigating the cause of their death, but experts speculate that it might be due to fluctuations in the water's saline levels, reports China Daily.
LONDON - According to their latest report, Technavio analysts expect the global frozen fish and seafood market to exceed USD 60 billion by 2020, growing at a CAGR of over 4% during the forecast period.
According to Vijay Sarathy, a lead research analyst at Technavio for foodresearch, “The demand for seafood continues to increase globally due to the significant population growth in countries such as China, India, and Brazil. Moreover, the development of modern distribution channels along with technological improvements in the processing, packaging, and storage of seafood products also help market growth.”
Technavio’s lead food and beverage market research analysts have identified the following three factors that will drive the global frozen fish and seafood market:
-Growing desire for convenience -Emergence of fish or seafood as a light snack -Growing demand for frozen seafood
