"It's the best of the best. It makes one more beautiful," the shop owner said in Mandarin, holding up a picture of dried totoaba bladder. "You can oil it or put it in a stew," he continued. The middle-age seafood shop owner pointed to the picture and said it would cost about USD 100,000.
The totoaba's swim bladder is the priciest dried fish item in Sheung Wan, a neighborhood in Hong Kong. In a cluster of shops on a street commonly known to tourists and locals as Dried Seafood Street, exotic dried fare sit in giant tubs and glass jars, promising a variety of cures to a number of health ailments.
Shops have entire sections displaying dozens of types of fish bladders, ranging from USD 100 to thousands of dollars. Chinese culture has long believed fish bladder is rich in collagen, improving skin texture and maintaining youthful-looking skin.
The environmental group Oceana is calling for the federal government to require about 2,400 skimmer trawls to use turtle excluder devices, but the president of the state shrimpers association said there’s a lot more work to be done before that could happen.
Skimmer trawls have been exempt from the requirement to use the devices while other nets on larger boats have been forced to comply since the 1980s, according to Tuesday 24th of May 2016’s Oceana report, “TEDs for All Trawls: A Net Positive for Fishermen and Sea Turtle.”
The turtle excluder devices — TEDs — are metal grates fitted into the net that allow shrimp to be caught, but gives an escape hatch for turtles and larger fish. Without these devices, Oceana says too many turtles and other larger marine animals are killed and wasted.
“In 2013 alone, the Gulf of Mexico shrimp trawl fishery discarded an estimated 242 million pounds of seafood and ocean wildlife — about 62 percent of its total catch,” the report says.
Edwardsiella tarda and Flavobacterium columnare are two important intracellular pathogenic bacteria that cause the infectious diseases edwardsiellosis and columnaris in wild and cultured fish. Prediction of major histocompatibility complex (MHC) binding is an important issue in T-cell epitope prediction. In a healthy immune system, the T-cells must recognize epitopes and induce the immune response. In this study, T-cell epitopes were predicted by using in silico immunoinformatics approach with the help of bioinformatics tools that are less expensive and are not time consuming. Such identification of binding interaction between peptides and MHC alleles aids in the discovery of new peptide vaccines. We have reported the potential peptides chosen from the outer membrane proteins (OMPs) of E. tarda and F. columnare, which interact well with MHC class I alleles. OMPs from E. tarda and F. columnare were selected and analyzed based on their antigenic and immunogenic properties. The OMPs of the genes TolC and FCOL_04620, respectively, from E. tardaand F. columnare were taken for study. Finally, two epitopes from the OMP of E. tarda exhibited excellent protein–peptide interaction when docked with MHC class I alleles. Five epitopes from the OMP of F. columnare had good protein–peptide interaction when docked with MHC class I alleles. Further in vitro studies can aid in the development of potential peptide vaccines using the predicted peptides.
The squids are all right — as are their cephalopod cousins the cuttlefish and octopus.
In the same waters where fish have faced serious declines, the tentacled trio is thriving, according to a study published Monday 23rd of May 2016.
“Cephalopods have increased in the world’s oceans over the last six decades,” Zoë Doubleday, a marine ecologist from the University of Adelaide in Australia, and lead author of the study, said in an email. “Our results suggest that something is going on in the marine environment on a large scale, which is advantageous to cephalopods.”
Dr. Doubleday and her team compiled the first global-scale database of cephalopod population numbers, spanning from 1953 to 2013. It included historical catch rates for 35 cephalopod species, including the Japanese flying squid, the giant Pacific octopus and the common cuttlefish. The species inhabit marine ecosystems all over the world, from Australia and the United States to Morocco and Madagascar, among other countries.
Along the West Coast, lingcod fish are top predators — voracious eaters that aren’t picky about where their next meal comes from.
But lingcod in the Pacific Ocean used to be overfished, to the point where managers created protected areas for these fish and other depleted groundfish species, such as yelloweye and canary rockfish.
Lingcod have recovered well with commercial and recreational fishing restrictions and closures, called rockfish conservation areas, and now are benefitting from these “safe zones” where they can escape the net of a fisherman. Alternatively, some rockfish species also designated as overfished haven’t yet recovered, even with vast fishing closures.
Scientists at the University of Washington together with The Nature Conservancy and West Coast fishermen are hoping to find a win-win solution to this imbalance. Specifically, the UW looked at whether fishing for lingcod in closed areas using an innovative approach could still allow sensitive species to continue recovering. Their study, published in May 2016 in the ICES Journal of Marine Science, found that selectively fishing for lingcod in protected areas actually avoided hampering the recovery of other fish, including rockfish species listed as overfished.
The scheme targets to develop large-scale tilapia cultivation with diversified and high-value products for both domestic and foreign markets; ensure supply of fries for breeding; control diseases; and raise income for farmers.
By 2020, total tilapia cultivation area would touch 33,000 hectares and 1,500,000 m3 of farming cages on rivers and reservoirs. Tilapia output would reach 300,000 tons, 50-60% of which would be qualified for export. The scheme aims to generate 54,000 jobs.
By 2030, the total cultivation area would increase to 40,000 hectares and 1,800,000 m3 of farming cages on rivers and large reservoirs. Tilapia output would be 400,000 tons, 45-50% of which would serve for export. The sector would churn out 67,000 direct jobs and 8,000 indirect ones.
MIAMI – The oceans are warming and coral reefs are dying, but octopuses, squids and cuttlefish appear to be thriving, with theirnumbers steadily rising over the past 60 years, researchers said hace said.
The findings, based on a global database of cephalopod catch rates devised by researchers at the University of Adelaide, were reported on Monday in the journal Current Biology.
"Our analyses showed that cephalopod abundance has increased since the 1950s, a result that was remarkably consistent across three distinct groups," said lead author Zoe Doubleday.
She said cephalopods may be benefiting from the changing environment because of their "unique set of biological traits, including rapid growth, short lifespans and flexible development."
ÐÀ N?NG – Nearly 1,500 voters in Mân Thái ward in Son Trà District cast their votes for deputies to the 14th National Assembly and all-level People’s Councils this morning.
Of 11,000 people living in the ward in Son Trà peninsula, some 30 per cent of these residents are believed to be living in poor conditions.
Also on May the 22nd of 2016, over 4,000 fishermen living in the ward docked their boats at Th? Quang fishing port so they could vote.
Fisherman Tr?n Van Chi?n, 49, said he completed his day’s fishing about 4am so he could return to vote.
“I earn my living from inshore fishing along the coast of Mân Thái – a defunct ancient fishing village in Ðà N?ng City. I cast my vote for the eligible candidates with a hope that they would help improve living standards and incomes for fishermen,” Chi?n said.
Minister for Animal Husbandry, Fisheries and Dairy Talasani Srinivas Yadav on Monday 23rd of May 2016 announced supply of fish seed to fishermen on 100 per cent subsidy. He said the government would also fund construction of four fish markets, one each at Adilabad, Nirmal, Mancherial and Bhainsa.
The Minister was interacting with fishermen and shepherds at Adilabad during his one-day visit to the district when the demand for supply of fish seeds on concessional rate came up. He assured the two communities of all help from the government towards betterment of their status.
Mr. Yadav first inspected the dairy unit at Nirmal and sanctioned Rs. 50 lakh for strengthening milk procurement and chilling. He distributed milk cans among members of women self help groups. The Minister announced an incentive of Rs. 4 per litre on milk production so that it helps poor farmers.
At Parimandal in Mamda mandal, he inaugurated cleaning of a 100-year-old water tank at a cost of INR 1.7 crore.
