3 HATCHERY FEED GUIDE 2013 Introduction Hatcheryfeed.com was launched in 2012 as an offshoot of Aquafeed.com, in response to requests for dedicated information for this specialized area of the industry. Over the past several months we have been adding to the site and have produced newsletters and started a Facebook page and LinkedIn discussion group to help bring hatchery operators together. The one question we continue to be asked is Who supplies hatchery feeds? This publication is a first attempt to answer that question. The Hatchery Feed Guide and Year Book brings together information about hatchery feeds available on the market today. It makes no claim to be comprehensive, but we hope this first issue is a step towards making the lives of hatchery operators a little easierat least when it comes to finding and selecting feeds. We hope you will give us some feedback on what you like and dont like and what you would like to see in the next one. A note about the listings: we have relied entirely on information provided by suppliers in the compilation of the listings in this guide [See complete Disclaimer information]. We appreciate the time these companies have taken and the encouragement they have given us. If you supply hatchery feeds and your products are not included we apologize; please email me to make sure we contact you in time for the next issue. We also thank the editorial contributors for the articles that are included. Please feel free to share this publication: forward it to your friends and colleaguesbut please keep in intact.

5 HATCHERY FEED GUIDE 2013 ADVANCES IN LIVE FEED Gunvor ie describes the work being carried out by Scandinavian research group, SINTEF Fisheries and aquaculture, on plankton and juvenile technology In SINTEF Fisheries and aquaculture we find a research group working with different live feed organisms. This group consists of scien- tists with different backgrounds; some are cybernetics, some are working with microbiol- ogy and biology, and some are biochemists. Some of the scientists have more than 25 years experience in live feed research. The group works with development of new tech- nology and automation of processes in the live feed production and in first feeding of fish lar- vae.

7 SUPPLIER FOCUS Reed Mariculture Inc: Hatchery Feeds Pioneers REED MARICULTURE (RMI) is the world's largest producer of marine microalgae concentrates. Our Instant Algae larviculture feeds are used by over 500 hatcheries, universities, and marine ornamental operations in more than 80 countries around the world. We also produce and distribute clean, hatchery-scale rotifer and copepods starter cultures, Otohime and TDO weaning and juvenile feeds, and related supplies. Markets Served: Commercial aquaculture; public aquariums; public and private researchers; breeders; and aquarium retailers and hobbyists. Cutting Edge Products: Instant Algae products are clean, effective and closer to nature than other feeds on the market. We produce whole-cell, whole-food microalgae feeds and enrich- ments using proprietary processes. Our products provide fish, bivalve and shrimp hatcheries with clean, convenient, long shelf-life feeds that can replace in-house microalgae. Our feeds ensure stable and rapidly-reproducing populations with excellent nutrition. Extraordinary Customer Service: We pride ourselves on our customer service and techni- cal support, and are also experts in world-wide shipping logistics. History of Innovation: Reed Mariculture was founded in 1995 by Tim Reed to grow tank-raised urban aquaculture oysters that would be safe and harvestable year-round using new technologies for large-scale grow out of marine microalgae, the feed for shellfish. In 1998 RMI changed its focus to selling the microalgae directly to other hatcheries. RMI's current core technology is a proprietary closed-system photobioreactor design that allows microalgae to be grown in clean, controlled conditions a radically different technology than the open-pond technology used for most commercial algae production. In 2003 RMI expanded its larviculture products with the introduction of live zooplankton (rotifers, copepods, and Mysid shrimp), and by distributing products such as ClorAm-X (for ammonia control) and Otohime Feeds (Japanese weaning and juvenile diets). In 2004 RMI entered the home aquarium market with the introduction of the Phyto-Feast prod- ucts, super concentrates of marine microalgae formulated for feeding coral, clams and other filter feeders popular in marine reef tanks. RMI has continued to ex- pand into the Marine Ornamental industry with the Reef Nutrition product line, which includes marine microalgae, macroalgae, rotifers, copepods, mysid shrimp, and other feeds. In 2011 Reed Mariculture launched an exciting new product line AP- Breed Hatchery Solutions for Aquarists, Propagators and Breeders. APBreed bridges commercial, ornamental and research hatchery technology and provides researchers with feed solutions customized for their unique needs. See our product listings in this guide.

8 HATCHERY FEED GUIDE 2013 EFFECTS OF DIETARY PLANT OILS ON FEMALE WHITE BASS MORONE CHRYSOPS EGG COMPOSITION AND PROGENY SURVIVAL White bass have been found to require considerable amounts of n-3 LC-PUFA in the diet to achieve maximal reproductive success. By Heidi Hill, Jesse T. Trushenski, Ryan L. Lane, and Christopher C. Kohler, Fisheries and Illinois Aquaculture Center and Department of Zoology, Southern Illinois University Carbondale, Illinois, USA. The dramatic increase in demand (Tacon and Diet-related changes in Morone spp. gamete Metian 2008) coupled with the apparent fatty acid composition have resulted in altered plateau in reduction fisheries landings (Pauly reproductive performance and early life et al. 2002) has led to significant research history success (Lane et al. 2006; Lane et al. into plant-based alternatives to fish meal and 2007; Lewis et al. 2010).

Morone spp. seem to lack this ability , and replacing dietary fish oil with plant oils has resulted in significant changes in the fatty acid profile of Morone chrysops eggs (Lane and Kohler 2006; Lewis et al. 2010) and other tissues of Morone hybrids (Wonnacott et al. 2004; Lane et al. 2006; Lewis and Kohler 2008; Trushenski et al. 2008a).

Evidence of this deficiency was apparent as reduced survival of the plant oil-fed progeny was observed in re- lation to broodstock fed fish oil in a previous study (Lewis et al. 2010). Replacing LC- PUFA with C18 PUFA would improve the oxidative stabil- ity of fish tissues, since C18 PUFA are less prone to lipid peroxidation than LC-PUFA b (Gonzalez et al. 1992). In a previous paper (Lewis et al. 2010), we speculated that low hatch and larval survival rates among white bass lar- vae may be due to increased lipid peroxidation within eggs containing high concentra- tions of LC-PUFA.

Distributive Figure 4 Pelleted and crumbled mixing (measure of mixing intensity/ efficiency) is greatly improved and more pre- dictable if component ratios are greater than 5 - 7% of total batch size (J.M. Ottino, Kine- matics of Mixing: Chaos and Transport, 1990). The third consideration for pellet homogeneity is particle size. A general rule for homoge- nous pellet production is that the mean parti- cle size of the dry raw materials should be in the size range of 1/3 to 1/5 of the desired pel- let size. For example, if the target pellet size is 1 mm, then the targeted mean particle size after grinding should be in the range of 300 to 500 microns. For reference comparing good particle size to poor particle size, and the Figure 5.

The dark spots are rendered from the extreme heat invoked on the process by the pellet mill, with the product being squeezed at high levels of mechanical energy through the small orifices in then die, and the sharp edges found on each pellet created by the crumbling process. The over-heated dark spots will reflect reduced feed functionality due to the destruction of vital vitamins and supplements, while the sharp edges will invariably effect mortality rates due to mouth injuries of the stock. Note the sample in Figure 5 shows a substantial reduction of both dark spots and sharp edges.
