Every year, The Marine Aquarium Conference of North America brings together aquarists from all over the world. They gather together to enjoy three days of interesting and informative talks by world renowned aquarists, presentations by the aquarium industry’s top...
A large, aggressive species, such as a queen triggerfish, is sometimes best kept singlyA diverse community of marine fishes presents quite a visual feast, especially when housed in a reef system brimming with colorful corals. However, in some stocking situations, it’s preferable to avoid the “typical” marine community (if there is such a thing) in favor of a single-species or even a single-specimen tank. Ah, but if you limit your livestock to a single species or specimen, won’t that make for a real yawner of a tank? On the contrary, sometimes systems that put the focus exclusively or primarily on a particular species or individual are among the most fascinating to observe.Here are five circumstances that warrant going single-species or single-specimen: 1. The shy, specialized feeder Seahorses, which are slow, awkward swimmers, shy by nature, and very specialized, methodical feeders, come to mind here. In your average community aquarium, these fish would basically be doomed, as they’d be unable to compete with bolder, faster-moving tankmates for food and would be unable to tolerate the brisk water movement typical of such systems. Not to mention, a community tank of any appreciable size would make it extremely difficult to provide the steady supply and high concentration of suitable food items necessary to sustain seahorses. On the other hand, in a small dedicated system with very gentle current, no competition for food, and suitable “hitching posts” to cling to, a group of seahorses can make for a truly mesmerizing display
LONG BEACH (CBSLA.com) — When it comes to getting some much-need rain in the Southland, El Niño has been a letdown – at least so far. But as CBS2’s Jasmine Viel reports, the weather phenomenon may be responsible for pushing rare sea creatures into our waters. Diver Roger Hanson says he couldn’t believe what he found twice Sunday just off the Long Beach coast: a rare Pacific seahorse calmly gliding above the ocean floor in just a few feet of water. “I was shocked,” said Hanson. Hanson had last spotted the spiny curvaceous creature last month, but his determination to capture this seahorse on camera in the chilly water came with a price. “Once I saw the seahorse, I stayed out
Dwarf Seahorses among Galaxaura subverticillata, one of the macroalgaes they associate with in the wild. 2016 will see wild Dwarf Seahorse Hippocampus zosterae gain new protections in the waters around Florida. These regulations are designed to limit their harvest from the wild in order to sustainably manage Dwarf Seahorse populations. The proposed regulations: Recreational bag limit: reduce the current limit of five (5) of each species of seahorse (within the 20 organism aggregate bag limit for all Marine Life species) to five (5) seahorses total per person per day Commercial trip limit: reduce the current daily commercial limit from 400 dwarf seahorses to 200 per person or per vessel (whichever is less) Establish an annual commercial quota of 25,000 individual dwarf seahorses and provide for closure of the recreational and
Seahorse mid strike; hyoid bone visible which is part of the complex musculoskeletal system seahorses utilize in suction feeding. This can be damaged easily. Photo by Tami Weiss You may have heard of ‘weak snick’, a common description of a clinical sign in syngnathids whereby attempts to feed appear weakened, that is, they don’t produce the nice ‘click’ sound you like to hear when healthy syngnathids strike at their prey. Multiple causes have been attributed to this particular clinical sign however in some severe progressive cases; this has been suspected to be due to a nutritional myopathy, which simply means a muscle disease caused by a nutritional imbalance. The suspected nutritional myopathy can present in many ways including: lethargy, weak snick, inappetence, and in severe unresolved cases,
Seahorses can be found along many shorelines frequented by people. Photo by Caio R. N. Periera cc-by/nc So you’ve found a seahorse, and you want to keep it. Or maybe you stumbled across one washed ashore, and are unsure what to do next. This question comes up from time to time. It’s not frequent, but it does happen enough that I wanted to provide some guidance. Release It! The best thing to do is to release the seahorse back where you found it, if at all possible. The sooner you can do this, the better off the seahorse will be. This is especially true for those found washed up on the beach, as can happen from time to time due to seahorse’s poor swimming abilities.
