 A great short review of pharmaceutical contamination on fish. Our waters are becoming polluted with human drugs and this study looked at the possible results. 
 
Fish species around the globe are at risk due to the ever-increasing levels of pharmaceutical contamination that is making its way into water systems, according to collaborative research conducted by The University of Western Australia, Monash University, the Swedish University of Agricultural Sciences, and New York University.

Some great ideas on plants to repel those nasty bugs without using chemicals that are potentually harmful to your koi. 
 

These poor koi did not stand a chance with these predators!
 
An otter with very expensive tastes was filmed eating more than £1,000 worth of koi fish from a garden pond.
The initial prime suspect had been a local heron before a CCTV camera captured the brazen otter in the act on Saturday.
Safety nets and protective wiring had just been installed over the pond in Edinburgh, but they proved no obstacle for the greedy animal.
Footage shows the otter chasing the fish at spectacular speeds, as an equally hungry fox watches from the edge.

Depending where you live in the world, your pond will have different critters that can been seen if you look close.  Here are some from Britain.
 
Summer is a time to leave your pond and its wildlife in peace. However, by looking at your pond at night, you might be surprised at what creatures come out when the sun goes down.

As pond owners and koi hobbyests, we all hate to see this in the news!
 
 ST. GEORGE, Utah — Dumping unwanted goldfish or other aquatic pets into reservoirs might seem like a humane way to dispose of them, but these invasive species can wreak havoc on fisheries, the St. George News reports.

Something we all dread as pond owners, and then we must solve the mystery.
 
On Saturday, eight days after the die-off at Danly’s house in North Coconut Grove, her neighbors awoke to a similar ghastly sight. Lee Marks and Daliana Mantegazza, koi collectors for 30 years, lost about 150 of the fish prized for the exotic coloring that makes it look like they’ve been painted. The sobbing couple and their sons frantically tried to save them by jumping into the pond and transferring fish into bins filled with fresh water. Only a dozen survived.
 

The amazing powers of bioflim and it's future potental.
 
Researchers have demonstrated that a slimy, yet tough, type of biofilm that certain bacteria make for protection and to help them move around can also be used to separate water and oil. The material may be useful for applications such as cleaning contaminated waters.

Amazing research about damselfish domesticating shrimp!
 
...Now, researchers have discovered fish that seem to be using shrimp in the same way we would use a farm animal.
The team thinks it could be the first example of a vertebrate species – other than human – domesticating another animal.

An interesting story of tossed out goldfish in a lake and its consequences. 
 
The most likely culprit behind the invasive species? Pet owners who illegally dumped goldfish, officials say.

Another story on fishless fish food. 
 
After six years of research, a team of scientists at the University of California, Santa Cruz has developed a cost-effective new aquaculture feed that eliminates conventional fish meal and fish oil ingredients while also providing better fish weight gain and higher nutritional value in the filet for humans. The new fish-free feed is the first to demonstrate across-the-board gains in sustainability, performance, economic viability, and human health.
