How Ocean Rider Is Fighting to Save Seahorses

seahorse in hand Otávio Nogueira cc 1200x694 How Ocean Rider Is Fighting to Save Seahorses
Ocean Rider, as part of their Seahorse Hawaii Foundation efforts, announced late last year that it was going to be reintroducing seahorses back into the wild in a few locations. On the surface, this sounds like a great step towards conservation. Reintroduction programs are very popular with the public, and who wouldn’t want seahorses reestablished in the wild? Unfortunately, these types of reintroduction programs have limited success, and can actually do more harm than good. It is true that seahorses are at risk from overfishing. But they haven’t disappeared from the wild, making programs to reestablish them moot. Reintroduction programs are generally only beneficial in places that a species has been wiped out completely, and only when the conditions that caused their decline are reversed. Seahorses are still found all over the world, no single species lost from it’s native range. Nor are any critically endangered, for that matter. The sad truth is that the Seahorse Hawaii Foundation’s reintroduction program is ill-advised and unnecessary, and potentially harmful.

Grumpy Seahorses Growl When Goaded

giantbrazilian 300x225 Grumpy Seahorses Growl When GoadedAlthough they usually exude peacefulness and elegance, research recently published in the Journal of Zoology has revealed that Seahorses possess a distinctly more assertive side to their character, and can even emit a deep and angry ‘growl’ in certain situations.  Examining the acoustic behaviour of Hippocampus reidi (Long-snouted seahorses), the researchers used a specially sound-proofed aquarium, equipped with a hydrophone and video camera, to document the clicking sounds that the seahorses make during reproductive behaviour and when feeding. They were also surprised to discover however, the previously un-described growling noises which were made when the seahorses were under stress, such as when they were being handled. Interestingly, the relatively low frequency growl was also accompanied by a vibration of the seahorse’s body and it is thought that the reaction may be an escape mechanism produced to startle predators. More: Grumpy Seahorses Growl When Goaded

5 Ways Hobbyists Misuse Grazing Marine Snails

astrea snail 300x169 5 Ways Hobbyists Misuse Grazing Marine SnailsOf all the fascinating invertebrates available to marine aquarists, grazing snails are perhaps the most misused. Too often we treat them like expendable little lawnmowers, plopping them in our tanks with the express purpose of preventing or eradicating algae and then replenishing them as their populations inevitably wane. But if treated properly, snails can be long-lived tank denizens that not only perform a useful purpose but also provide interest in their own right. So what do I mean by “misusing marine snails”? Here are some of the more common improper practices when stocking grazing gastropods: 1) Stocking in excessive numbers I implore you to ignore any advice along the lines of “To control algae X, add Y number of snails per every Z gallons of aquarium volume.” There is no correlation between the volume of water an aquarium can hold and the number of grazing snails the system can support long term. It all comes down to food supply. Simply put, the system must contain adequate, ongoing growths of the appropriate algae to sustain the type/number of snails you introduce. Otherwise, your grazing gastropods will quickly eat themselves out of house and home and begin starve to death. It’s always best to start with just a few specimens, observe how they perform when it comes to keeping algae in check, and then add more only if necessary. 2) Stocking cold-water species in tropical tanks Some marine snails sold to unwitting hobbyists for the purpose of algae control—often as part of a “cleanup crew”—are actually from temperate waters and won’t survive long in tropical aquariums More: 5 Ways Hobbyists Misuse Grazing Marine Snails

New Project Aims to Value Coral Reef’s ‘Natural Blue Capitol’

download New Project Aims to Value Coral Reefs Natural Blue CapitolThe governments of the Philippines and Australia collectively have launched a new project, The Capturing Coral Reef and Related Ecosystem Services (CCRES), that aims to quantify the market value of the Country’s coral reef and mangroves, also known as ‘natural blue capital’. The study will be research based, focused on the effects of services provided by healthy coral reef and mangrove ecosystems. The director of the Biodiversity Management Bureau, Theresa Mundita Lim, said “The project will help us convince stakeholders that the environment is a good investment as it benefits the communities,” Lim said. The project will start in the El Nido region of the Philippines, a protected area which covers over 140 square miles. Hopefully this project will be succesful in leading the way for sustainable enterprises that can lesson climate change effects and protect our reefs. MORE

Innovative Marine to Offer Mesh Screen Lids for NUVO Nano Aquariums

fa63NUVO Nano Mesh Screen Lids Innovative Marine to Offer Mesh Screen Lids for NUVO Nano Aquariums
When Innovative Marine launched their NUVO Shallow Reef and Fusion series aquariums, they thought out the designs through eyes of aquarium keepers, adding specific accessories that would yield massive benefits. One of these features was the mesh screen that covered the tops of these aquariums, keeping jumpy fish from doing a little carpet surfing. While this screen comes stock with the two higher end systems, IM has decided to release a line of screens to fit many of their popular NUVO Nano aquariums. This upgrade consists of a lightweight mesh screen with a durable powder coated aluminum frame and will fit nicely over the NUVO Nano16, Micro30, and Mini38 aquariums. There are no tools required for the install, and since the screen comes preassembled, all you have to do is tear open the box and set it on your tank, simple as that. Here is a full model breakdown, which includes dimensions and suggested retail prices. -16 Gallon Screen Dims: 22.85” x 8” x 0.35” ($40 MSRP) -30 Gallon Screen Dims: 19” x 13.25” x 0.35” ($50 MSRP) -38 Gallon Screen Dims: 22.75” x 13.25” x 0.35” ($60 MSRP) MORE: Innovative Marine to Offer Mesh Screen Lids for NUVO Nano Aquariums
