Aquatics and Fishkeeping
UNIT 21: AQUATICS AND FISHKEEPING Unit 21: Aquatics and Fishkeeping Unit code: J/503/1723 QCF level: 5 Credit value: 15 x Aim This unit aims to develop learner understanding of fish biology, aquatic invertebrates and aquatic management, as well as their practical skills in maintaining of aquatic species in appropriate conditions. x Unit abstract In this unit learners will explore the factors that an aquarium employee or ornamental fish farmer need to understand. The unit focuses on the work involved at an aquarium, aquatic centre, specialist pet centre or similar, and the ideas in this unit are major considerations for this area of the industry. Certain aquaria around the world use these skills to support species on the verge of collapse and, as such, have developed in-depth breeding programmes. Examples of the skills developed in this unit can be seen around the world for example an aquarium in California has been able to establish Scorpion fish in captivity, a species notoriously difficult to breed, by applying a knowledge of water requirements and health management strategies. x Learning outcomes On successful completion of this unit a learner will: 1 Understand the taxonomy and biology of ornamental aquatic species 2 Be able to establish, monitor and interpret freshwater and marine community aquaria and ponds 3 Understand appropriate aquatic health management strategies 4 Understand procedures and practices relating to the acquisition, transportation, holding and supply of aquatic organisms.

Takifugu Niphobles
Joseph Fratello Marine Biology Professor Tudge 10/16/17 Takifugu niphobles Introduction: The Takifugu niphobles or the Grass Puffer is a small fish that resides in the shallow waters of the Northwest Pacific Ocean. The scientific name of the fish comes from the japanese words of taki meaning waterfall and fugu meaning venomous fish (Torres, Armi G., et al). The Takifugu niphobles is part of the family Tetraodontidae which encompasses all puffer fish and are known for their ability to inflate like a balloon. The fish do this by quickly sucking water into their stomachs causing them to inflate and causing the flat lying spines which cover their bodies to become erect. Their diets consist of a wide array of small crustaceans and mollusks (Practical Fishkeeping, 2010). Takifugu niphobles are one of the two most common fish in the Northwest Pacific Ocean and are often accidently caught by fishermen who employ the bottom longline technique (Shao K, et al., 2014). The sale of these fish, including other puffers, are banned in japanese markets due to their highly toxic nature. Yet, puffer fish are considered a japanese delicacy despite the fact that a wrong cut of meat can kill a fully grown man. Upwards of thirty to fifty people are affected by the toxin every year and chefs must undergo two years of training before they can legally sell the fish (Dan Bloom 2015). These fish have a very unique means of reproduction, in which they swim towards the shore and lay their eggs on the beach. The fish then, with the help of the waves, beach themselves and fertilize these eggs. -
Aquacultue OPEN COURSE: NOTES PART 1
OPEN COURSE AQ5 D01 ORNAMENTAL FISH CULTURE GENERAL INTRODUCTION An aquarium is a marvelous piece of nature in an enclosed space, gathering the attraction of every human being. It is an amazing window to the fascinating underwater world. The term ‘aquarium’is a derivative of two words in Latin, i.e aqua denoting ‘water’ and arium or orium indicating ‘compartment’. Philip Henry Gosse, an English naturalist, was the first person to actually use the word "aquarium", in 1854 in his book The Aquarium: An Unveiling of the Wonders of the Deep Sea. In this book, Gosse primarily discussed saltwater aquaria. Aquarium or ornamental fish keeping has grown from the status of a mere hobby to a global industry capable of generating international exchequer at considerable levels. History shows that Romans have kept aquaria (plural for ‘aquarium’) since 2500 B.C and Chinese in 1278-960 B.C. But they used aquaria primarily for rearing and fattening of food fishes. Chinese developed the art of selective breeding in carp and goldfish, probably the best known animal for an aquarium. Ancient Egyptians were probably the first to keep the fish for ornamental purpose. World’s first public aquarium was established in Regents Park in London in 1853. Earlier only coldwater fishes were kept as pets as there was no practical system of heating which is required for tropical freshwater fish. The invention of electricity opened a vast scope of development in aquarium keeping. The ease of quick transportation and facilities for carting in temperature controlled packaging has broadened the horizon for this hobby. -

FEEDING TINY FRY” SWAM, Jan/Feb 1985
“FEEDING TINY FRY” SWAM, Jan/Feb 1985 by Chase Klinesteker Newly hatched Rainbow fry Since Lyle Marshall asked for an article on feeding fry too small to eat baby brine shrimp, I thought that I would put in my 2 cents worth. I have probably had failures numbering well over one hundred for this reason alone (I won’t talk about the many other reasons why spawns have not survived for me). My ratio of attempts to successes is about five to one for egg laying fish in general. So, taking the advice of this article may be like asking a .200 baseball hitter to instruct you in batting techniques, but here goes anyway. THE PROBLEM The biggest enemy of tiny fry is pollution and bacteria in the water. It seems they both go hand-in-hand. Organic debris particles and molecules are slowly broken down by bacteria. Decaying plant leaves and fish wastes are good examples of organic debris. In a normal aquarium that is not overcrowded or overfed, the bacteria grow in numbers. But, just as quickly, tiny single celled water animals (infusoria) reproduce and consume the excess bacteria, not allowing them to overpopulate, consume oxygen, and produce excess wastes. It is the infusoria that are excellent food for the tiny fry, whose mouths are so small that they can’t consume newly hatched brine shrimp. This may be true for a few days to 2 weeks for some fry. The real dilemma in culturing infusoria is that their food (bacteria) is deadly to the fry. Getting a good infusoria culture to its’ peak with maximum populations of infusoria and minimum populations of their food (bacteria) is a challenge I have been unable to master consistently. -

Biology, Husbandry, and Reproduction of Freshwater Stingrays
Biology, husbandry, and reproduction of freshwater stingrays. Ronald G. Oldfield University of Michigan, Department of Ecology and Evolutionary Biology Museum of Zoology, 1109 Geddes Ave., Ann Arbor, MI 48109 U.S.A. E-mail: [email protected] A version of this article was published previously in two parts: Oldfield, R.G. 2005. Biology, husbandry, and reproduction of freshwater stingrays I. Tropical Fish Hobbyist. 53(12): 114-116. Oldfield, R.G. 2005. Biology, husbandry, and reproduction of freshwater stingrays II. Tropical Fish Hobbyist. 54(1): 110-112. Introduction In the freshwater aquarium, stingrays are among the most desired of unusual pets. Although a couple species have been commercially available for some time, they remain relatively uncommon in home aquariums. They are often avoided by aquarists due to their reputation for being fragile and difficult to maintain. As with many fishes that share this reputation, it is partly undeserved. A healthy ray is a robust animal, and problems are often due to lack of a proper understanding of care requirements. In the last few years many more species have been exported from South America on a regular basis. As a result, many are just recently being captive bred for the first time. These advances will be making additional species of freshwater stingray increasingly available in the near future. This article answers this newly expanded supply of wild-caught rays and an anticipated increased The underside is one of the most entertaining aspects of a availability of captive-bred specimens by discussing their stingray. In an aquarium it is possible to see the gill slits and general biology, husbandry, and reproduction in order watch it eat, as can be seen in this Potamotrygon motoro. -
