IN BRIEF - Threats of Aquaculture on African ecology
Friday, November 10, 2017
Fish farming is a method that started showing its negative impact in recent years. Invasive species introduced by aquaculture businesses are invading and changing the ecosystem of places like the Okavango delta, Lake Malawi and Lake Victoria.
Is aquaculture causing more harm than solving fishing crisis?
Fish farming was introduced to Africa by the previous colonial authorities as a way to improve the production in the field of fisheries and accommodate to the growing population’s need. However, economic growth does not always resonate with suitable mindful techniques and environmental wellbeing. Although fish farms are producing an important amount of goods to cater to the needs of the population, their owners are generally unaware of the ecological drawbacks that their business is entailing. These farms are indeed contributing to the wellbeing of the communities benefiting from them but the negative side of the business shouldn’t be overlooked. Raising awareness about the harmful side to introducing certain types of fish should be a priority in this field.
Certain species are said to grow faster than others but according to specialists like Martin Genner “there is zero evidence that Nile tilapia will grow faster or have a better food conversion efficiency than local tilapia species when kept in the same conditions.” He also added “everyone is under the illusion that their problems will be solved by having a different fish species.” Aquaculture has a good potential within the continent if it is wisely and smartly applied.
Bhubaneswar - Traditional fishermen have urged state government to relax the ban imposed on fishing in the sea to protect olive ridley turtles as they are facing livelihood threat.
They have also sought a raise in the compensation offered by the government to compensate for the fishing ban. The seven-month-long ban, clamped on November 1 2017, will affect nearly 30, 000 fishermen in the coastal districts, especially Kendrapara and Jagatsinghpur.
"The ban on fishing is applied up to 20km in the sea from the shore. But that is illogical for the traditional fishermen. Their small boats equipped with outboard engines cannot go that far into the sea. The prohibition on fishing should be restricted to an area of 10 km," said Narayan Haldar, president, Odisha Matsyajivi Forum.

CLEMENTS, San Joaquin County - Salmon crowded in and around the Mokelumne River Fish Hatchery on Thursday, offering leaping and squiggling proof of what so far is a near-record return of the big pinkish delicacies after several years of low breeding numbers.
Schoolchildren watched as the fall-run chinook squirmed on conveyor belts into the “egg take” building, where, with help from about a dozen hatchery workers, they engaged in the decidedly unromantic process of spawning the next generation.
“It’s going to be one of the top three or four years that we’ve seen since 1940,” said Jose Setka, the manager of fisheries and wildlife for the East Bay Municipal Utility District, which supplies Mokelumne River water to 1.4 million East Bay customers. “We are getting more of our fish back where they belong.”
The Department of Agriculture (DA) is eyeing Russia as an “exciting” market for the Philippines’ shrimp industry, its top official said.
Agriculture Secretary Emmanuel Piñol, who was guest of honor at the 11th National Shrimp Congress held at SMX Convention Center in Bacolod City Thursday, said he recently talked with his Russian counterparts in Vietnam, during a bilateral meeting.
Piñol was with President Rodrigo Duterte, who met with Russia President Vladimir Putin.
In that meeting, Putin was very emphatic in telling Duterte to start delivering agriculture products as they have the money, he said.
“This is where I would like to bring the shrimp industry,” Piñol said, adding that Russia is the new exciting market “but we have to get our acts together. We cannot operate independently.”

The current emergency closure of some fisheries along the coast of Kaikoura is being extended to help the marine environment affected by the 2016 earthquakes to recover.
An emergency closure, in consultation with the local Kaikoura community, was imposed after the 2016 quakes and that applied to all shellfish and seaweed - excluding rock lobster (crayfish) and scampi.
MPI Acting Director Fisheries Management, Steve Halley, says the earthquakes had a devastating effect on the coastline between Marfell's Beach and the Conway River, raising the seabed by several metres in some areas.
Fish farms made EUR 6.6 million in 2016, almost half what they earned in 2015 despite a 21.9% increased in output.
This was due to a 30.6% increase in costs due to increases in overheads, selling costs, variable production costs, and in purchases of live tuna and other fish.
The National Statistics Office said on Wednesay that EUR 144.9 million of fish were sold, of which EUR 133 million were tuna.
In 2016, the volume of fresh fish sold amounted to 12,466 tonnes, an increase of 15.4% over the preceding year. This was due to increases in the sales of seabass and tuna of 43.7% and 25.5%, respectively. On the other hand, sales of other fish and seabream decreased by 73% and 5% respectively.
Starting today, Juneauites will have the chance to catch king crab in the waters surrounding their backyards. It’s the first time in six years a winter personal use fishery has been opened in Juneau area waters.
A total of 1,965 king crab have been allocated for the fishery. That’s up from 1,300 crab when the fishery was last opened in 2011.
“I would say it’s on the higher end of what we’ve had for a winter fishery allocation,” said Karla Bush, Southeast Region Shellfish and Groundfish Program Coordinator for the Alaska Department of Fish and Game.
Personal use red and blue king crab fishing is typically open in other areas close to Juneau, but not in the areas surrounding the city, where low populations have kept the fishery closed.
