Thailand boasts captive bred Parachaetodon ocellatus

 The Kite Butterflyfish is a unique member of Chaetodontidae that suffers from a state of taxonomic limbo. Placed in its own monotypic genus, Parachaetodon ocellatus adopts a somewhat atypical form with its significantly taller anterior profile. Recent molecular and morphological studies nests the species within Chaetodon, making Parachaetodon now defunct and obsolete. Although ocellatus is the oldest name for the species, the name is already taken by the Atlantic species Chaetodon ocellatus, which predates the use of ocellatus for this species. Should the move from Parachaetodon to Chaetodon were to occur, the Kite Butterflyfish would also require a change in its specific epithet, which means that it takes on the next available synonym – Chaetodon oligacanthus. The specific epithet “oligacanthus” translates to “fewer spines”, which was what dictated its initial placement in Parachaetodon. Although the molecular and morphological study strongly supports this change in its generic and subsequent specific status, it is still not widely accepted, and the Kite Butterflyfish in turn, masquerades under two aliases. … More:

Captive bred Lemonpeel Angelfish: Bali Aquarich’s virgin foray into the genus Centropyge

A pristine juvenile C. flavissima, born and raised in captivity.

 In the last couple of years, Bali Aquarich has cemented itself as the front runner in the captive breeding scene. The Indonesian based aquaculture company founded by Wen-Ping Su has won the world over not only with their stunning designer clownfish, but also their increasingly commendable repertoire of captive bred angelfish. This trailblazing icon has edged its way up the echelon of angelfish aquaculture wizardry, right there with the likes of Karen Brittain and Frank Baensch. It’s hard to believe that Bali Aquarich’s virgin foray into angelfish territory started only a mere three years ago, and today, Mr. Su is proud to add Centropyge flavissima to his growing list of captive bred accolades.… More:

Summer May be Over, But Things are Heating up at the Long Island Aquarium

12027365_10207968042781225_9088427346876719141_o Summer is over; fall has seized Long Island. The waters are cooling down, the tropical fish that we’ve enjoyed collecting all season will soon be gone from our bays and inlets. At the LI Aquarium, the summer exhibits are closing and the visiting crowds have changed from the wall-to-wall traffic of the summer to the school groups that descend on us in the fall. You might assume our job slows to a lull now, but you would be dead wrong. This is actually my busiest time of year. I have started ramping up my copepod productions and setting up my rearing vats, because guys… it’s aquaculture time! I am still in my first few weeks of egg collecting, and boy am I off to a great start. Last week, I saw my biggest spawn to date from my broodstock of Swiss Guard Basslets (Lipproma rubre). Pictured above is a newly-hatched rubre prolarva. At only 12 hours post-hatch, this prolarva is stunning- not only is its fin folds unique, but it is also bright and shiny in my rearing vats. Hatched at a whopping 3mm, these are one of the smallest prolarva I have ever worked on.… More:

The Isopod From Hell


Picture of 9 days post hatch larva with Cirolanid isopod attached

Today while checking up on one of my larval rearing tanks, I spotted something unusual. At first, I thought that one of the larvae had consumed something that was too large for it because it looked like its stomach was protruding. I removed the larva to further examine it under a microscope. To my surprise, I discovered that there was an isopod attached to my fine larva. It was a Cirolanid isopod of the order Isopoda. Cirolanids come in… More:

Check Out Our Wrasses!

As mentioned in our previous post, six adult melanurus wrasses (3 male, 3 female) were moved to the Tropical Aquaculture Lab back in February.  After settling into their new environment and being offered a conditioning diet of LRS Reef Frenzy, PE mysis shrimp and Otohime EP1 pellets, the wrasses have quickly got back into their routine of spawning nearly every night.  While we continue to work through some kinks in production, we wanted to share some of our excitement with our latest group of captive bred melanurus wrasses.   [embedded content] Video 1:  Melanurus wrasse broodstock spawning at dusk.  Notice in slow motion all three males can be seen making an attempt at fertilizing the female’s eggs.

Rabbitfish Fisheries Possible Model for Culture of Marine Ornamentals?

 Bagoóng is a traditional condiment for Filipino cuisine that is made of fermented fish or shrimp. Bagoóng isdâ, the fishy version, is fermented in brine for several months before it is finally prepared and packaged. This delicacy, which is typically used to enhance the flavor other foods, can be made in different ways with different types of fish. Especially popular is padas, a bagoóng isdâ that is prepared from the juvenile rabbitfish (Siganus spp.). A status symbol, it is customarily served during religious holidays. Vendors sell the specialty item in tightly packed jars in all kinds of shops and markets. Sometimes, the small fish are intricately and artfully arranged within the jar. For aquarists and aquaculturists, this would be just be an amusing factoid about one commonly kept family of fishes, were it not that intense demand for bagoóng padas products has led to a substantial fishery. Filipino farmers focus on several local rabbitfish species (collectively referred to as malaga or samaral), including Siganus canaliculatus, S. concatenates, S. corallinus and S. spinus. These fishes can easily sell for three times the price of common selections, so competition among producers is fierce. Today, in the Philippines, rabbitfish are a commercially-important fishery, contributing 560 million tons (with juveniles accounting for 60 million tons) to the total annual fishery production. That’s a lot of fish paste.  … More:

Aquaponics Fast Becoming A Preferred Method of Cannabis Cultivation

 Aquaponics is pretty simple in concept. Imagine an aquarium that is plumbed into a hydroponic system; fish wastes are mineralized by microbes and ultimately utilized by the plants as nutrients. Technically speaking, even a mangrove propagule stuck in the back of an overflow box is aquaponic. The benefits of this type of cultivation are significant. A major attraction for some growers is the ease with which the highly intensive method can be practiced organically. The taste of aquaponic foods (unlike that of hydroponicially grown foods) is said to be as good as its soil grown counterpart. Because there is no soil, pests are far easier to prevent and control. Aquaponics also dramatically reduces… More:

Commercially Available Porkfish

Figure 1. Captive bred Porkfish juvenile available fromFishEye Aquaculture. Three years ago we posted a blog stating the commercial production potential of Porkfish, Anisotremis virginicus (Porkfish Protocol – Rising Tide’s First Commercial Species). As you’ll recall, researchers at the Tropical Aquaculture Laboratory collected eggs spawned at SeaWorld Orlando and grew them to the juvenile phase and beyond. This was not the first time that Porkfish had been grown in captivity (again credit goes to Martin Moe and company). It was, however, the first time that Porkfish had been grown from eggs spawned in captivity using standard commercial production protocols; including the use of hatchery grown live feeds (rotifers and Artemia). This proved inspiring to one of Rising Tide’s industry partners who decided to add this fish to their list of available species. Figure 2. Captive bred Porkfish juveniles available fromFishEye Aquaculture is the world's leading destination for sustainable coral reef farming and the aquarium hobby. We offer a free open forum and reef related news and data to better educate aquarists and further our goals of sustainable reef management.
