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.

Rising Tide Intern Joe Frith

Hello Everybody!  My name is Joe Frith and I have been interning here at the Tropical Aquaculture Laboratory in Ruskin, FL for the past 2 months. I would first like to say “thank you” to Dr. Judy St. Leger, Eric, Kevin, Roy, Craig, Jon and the rest of the staff here at the Lab for giving me this opportunity and making this a meaningful experience. I’m currently an undergraduate at the University of Missouri-Columbia completing my degree in Fisheries and Wildlife with a minor in Biology

CORAL Excerpt – Project Coral: Inducing Predictable Broadcast Spawning of Stony Corals In Captivity

Project Coral – By Jamie Craggs | Coral Magazine, March/April 2014 The following excerpt is a selection from “Project Coral” by Jamie Craggs. Get it now in the March/April 2014 issue of CORAL Magazine Whilst there have been captive coral spawning events in a few public aquariums and a small number of home aquariums around the world, they have always been unplanned, incidental events, often catching the onlooker by surprise. So the challenge of spawning corals in a controlled, predictable way is considerable and presents some major obstacles. Despite this, I’ve always felt it could be achieved if the approach was right. When we attempt to breed aquarium animals, the method is the same in principle. First we need to research the individual environmental and/or nutritional components that trigger a species to reproduce in the wild; then, using that knowledge, we replicate these conditions in our aquariums. Surely, inducing broadcast corals like Acropora to spawn in captivity should be no different, even if their environmental cues and triggers are more elusive to define

Feeding Corals with Sustainable Aquatics Hatchery Diet

Scolymia eating Hatchery Diet pelletsIf you are unfamiliar with the Tidal Gardens coral farm, much of our aquaculture process depends on the fast growth of our corals and the long-term health of our colonies. Coral nutrition is a major factor. We constantly experiment with different foods for our coral. Corals that are fed consistently have dramatically improved coloration and display much better polyp extension. It’s always interesting to see coral colonies that we have had for years sitting next to colonies we recently acquired. They look like completely different animals in many cases. As much as we like to stuff our corals with food, some corals are not as receptive to feeding as others.
