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.

Essential requirements Sufficient library resources must be available to enable learners to achieve the unit, including a biological dictionary, a veterinary dictionary and a range of textbooks/media covering taxonomy, classification, fish anatomy and physiology, ecology, fish keeping, fish health, marine biology, pet trade, animal transportation, animal-related legislation, welfare and conservation. Learners will also need access to equipment/consumables including tanks, filters, thermostats, heaters, substrate, plant material, water quality test kits, transportation carriers, dissection kits, and fish models. Regular supervised access to a range of fish species for routine husbandry and management, and laboratory access, is essential and could be enabled by forming links with local aquaria or aquatics suppliers. Animal welfare requirements must be paramount at all times. Animals must not be subjected to stress or overuse during delivery of this unit. Employer engagement and vocational contexts Learners would benefit from having access to a suitable working environment. Often this can be achieved by establishing links with local businesses or charitable organisations who may benefit from taking on learners. Local aquaria and aquatic suppliers are a good source of information and are often keen to share their knowledge with students. Charitable organisations can provide guest speakers to give lectures and demonstrations.

  • 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.

  • API® Lesson 4 | Understanding Fish Mouth Types
    API® Lesson 4 | Understanding Fish Mouth Types This lesson plan provides a basic understanding of different types of mouths in fish. The position of the mouth can be an indication of feeding habits. Based on the type of mouth one can then determine the preferred location used to secure food. The shape of the mouth such as elongated, spear-like, or tubular can also shed light on feeding habits. For Instructor/Teacher/Parent Make sure to read through the entire lesson plan before beginning this with students/family members as materials needed for this lesson are an aquarium to observe, and paper and pencil for drawing. Learning Objectives After completing the activities outlined in this lesson plan, students should be able to: • Provide definition and description of varying fish mouth types • Preferred location of fish for feeding based on mouth type • Examples of teeth in fish • Basic understanding of sensory organs and purpose in and around the mouth Length This activity will take about 2 hours for completion of this exercise. Materials • Freshwater aquarium with a few varieties of fish (top, middle and bottom feeder fish) • Paper/Sketch Pad • Pencil to sketch fish mouth images • Three different food types o Floating food, such as API TROPICAL FLAKES o Sinking food, such as API BOTTOM FEEDER SINKING PELLETS o Bottom wafer-like food, such as API ALGAE EATER WAFERS Key Terms Review key terms (printable sheet included at the end of the lesson) with students/family members. 1) Terminal Mouth 2) Superior Mouth 3) Inferior Sub-Terminal Mouth 4) Barbels 5) Suction Mouth 6) Protrusible Mouth Warm Up Ask a couple of questions to warm up for the lesson: 1) Do you currently have any fish? Can you identify different mouth shapes? 2) What location in the aquarium do you typically see your fish intake their food? 3) What type of food do your fish eat? Before You Start 1.

In recent years, it has become increasingly clear there is substantial overlap in the shared goals for environmental and socioeconomic benefits between commercial stakeholders, the academic/conservation community, and zoos and public aquariums. Leaders in these three groups convened at Aquarama to discuss shared goals, shared challenges, and how a harmonized strategy may yield significant benefits to all. In the not too distant past, these three groups would not necessarily have viewed the others as partners; in fact, a certain degree of reservation towards each other was not uncommon. The sincere commitment to collaboration that took place at the Singapore meeting was, itself, a great step forward. The key perspectives of the three groups at this point can be described through the following examples: • Industry: Dr. Gerald Bassleer, President of Ornamental Fish International (OFI), expressed eagerness for trade members to support research on the industry.
