The traditional way of protecting fish against disease is to inject them individually with a vaccine.
But this can be time-consuming and manpower-intensive.
Singapore researchers have come up with a way around this - using a tiny nano material.
They have found a way to package a vaccine for a common bacterium in tropical waters, tenacibaculum maritimum, into a material 100,000 times thinner than a strand of human hair. The bacterium causes the scales of infected fish to fall off and their mouths to disintegrate.
The new method will allow fish farmers to vaccinate their fish stocks by immersing them in a container of water containing the "nanovaccine". It then enters the fish through their gills and skin.
"There is no need for skilled workers, and fewer workers are needed... making it cheaper," said Dr Jeffrey Seng, a senior lecturer at Nanyang Polytechnic's School of Chemical and Life Sciences. He led the development of the nanovaccine.
A national aquaculture curriculum has been launched to promote, boost and sustain farming of tilapia in fish ponds within the catchment areas of L Victoria, and outspreading countrywide.
The modular curriculum which will be offered in various vocational training institutions, polytechnics and colleges throughout the country, is part of joint efforts to sustain the declining fish population in L Victoria, enhance sustainable ways to protect the lake’s environment and eradicate poverty by creating alternate livelihoods other than lake fishing.
The curriculum which is part of the Trilateral Tilapia Cooperation, is a combined product Kenya’s Ministry of Agriculture, Livestock and Fisheries, the German Development Cooperation Agency, through Deutsche Gesellschaft für Internationale Zusammenarbeit GmbH (GIZ) and Israeli Foreign Affairs Ministry’s Agency for International Development Cooperation (MASHAV).
DHUBRI - With the Brahmaputra getting contaminated, the fish stock in the mighty river, has started depleting in Dhubri areas for the past few days.The district is known for different species of fish, but with the abnormal deviations in the colour and quality of its water, the fish stock has started deteriorating worrying fishermen.
Fishermen who generally earn their daily bread and butter by selling fish are now in a quandary. They have observed that the water of the Brahmaputra has turned muddy which has in turn affected the fish.
Gautam Das, a fisherman and supplier of Brahmaputa fish to various markets, said that during the winter season the Brahmaputra is full of with different species of fish, including ari, borali, chital, rohu and katla. However, these days, the fishermen are able to get a very small quantity while catching fish. He also stated that the chingri fish has suddenly disappeared from the river as none of the fisherman has caught it yet.
Agriculture is one of the fastest growing food sectors but with that growth has come a worrying trend in antimicrobial resistance (AMR).
New research has evaluated the options open to fish farmers to cut down on the use of antimicrobials, such as antibiotics, antivirals and antiprotozols.
WorldFish, a charity devoted to harnessing aquaculture to reduce poverty, undertook the research as part of its CGIAR ResearchProgram on Fish Agri-food Systems (FISH).
The study, Unpacking factors influencing antimicrobial use in global aquaculture and theirimplication for management: a review from a systems perspective, identifies the main factors and challenges of different antimicrobial use. This, the abstract said, “enables discussion of mitigation pathways”.
A group of Chinese investors is set to pump KES 1.2 billion (USD120 million) in Kisumu's struggling fish industry.

According to a Facebook post shared by Kisumu County Governor Peter Anyang' Nyong'o on Thursday, December 8, the investors unveiled the mega project while visiting the county's Deputy Governor Ochieng' Owili at his office.
NORTHERN PENINSULA, NL – In the midst of an ever-changing fishery, prospects for aquaculture projects along the Great Northern Peninsula are improving.
Cyr Couturier, an aquaculture research scientist and chair of aquaculture programs with the Marine Institute of Memorial University, says the possibilities are there, but can only succeed with hard work and serious investment.
“There is some potential for different types of aquaculture, land-based as well as ocean-based,” said Couturier. “It all depends on what species you’re talking about.”
“But it’s not for the faint of heart. If people are encouraged to invest and have the know-how, I’m sure they could do something.”
Products from the Falkland Islands Fish Company, the trading name of Fortuna Ltd’s new Stanley fish processing plant, were featured recently in China and attracted favorable attention from trade media.
Traditionally the Falklands fishing industry is a deep-sea operation with all the fish being caught, processed on board and frozen on the vessels, but when interviewed by Undercurrent News at the China Fisheries & Seafood Expo in Qingdao, James Wallace of Fortuna Ltdexplained that having a “fully owned plant 100 meters down the road” enabled the company to offer customers a wider variety of products than was normally possible and to guarantee quality.
Large-scale processing at sea limited companies to “producing basic products for small markets”, Mr. Wallace is quoted as saying.
Fish and chips could be more expensive after Brexit, MPs have heard.
Former minister Ben Bradshaw's warning came after his Labour colleague Mel Onn (Great Grimsby) urged the Government to ensure the UK avoids "absolutely catastrophic" consequences for fishing jobs and industry.
Ms Onn said Norway is always cited as an example of how British fisheries could thrive outside the Common Fisheries Policy (CFP) although she highlighted concerns over its position.
The Atlantic States Marine Fisheries Commission is requesting proposals to develop potential marine aquaculture projects in the U.S. Atlantic coast region. NOAA Fisheries, through the commission, is making USD 450,000 available for the funding period of April 1, 2018, to March 31, 2019. The Commission plans to award several projects ranging from USD 50,000 to USD 100,000 each, but will give consideration to projects that can justify a greater need.
Anyone seeking support for this period must submit, as a single file, an electronic proposal by email no later than 5 p.m. EST on Thursday, February 1, 2018. For complete proposal details, qualifying requirements and submission instructions, see the Request for Proposals (RFP).
The Gulf and Pacific States Marine Fisheries Commissions have also issued similar RFPs seeking proposals relevant to their respective regions.
