- What are the best methods for making money with aquaponics? - Which edible aquaponic fish species will generate the most revenue per pound? - Which aquaponic vegetables provide the highest profit margin? - Which fish and vegetables are in highest demand by consumers? - Do you know about all of the non-vegetable plants that can provide you with greater revenue than vegetable plants? - What costs are involved in setting-up and operating an aquaponic system? - What is the cost-benefit analysis of an aquaponic system? - Where and how can I sell my aquaponic harvest? - What regulations and legalities are involved in setting-up and operating an aquaponic business? - Did you know that there are other aquatic species that can be grown in aquaponics which can generate more revenue than the commonly grown edible aquaponic fish species? - What is the best way to barter my aquaponic harvest? - How can I get my products officially labeled as 'organic'? - What is the best approach to having a successful aquaponics business that will produce the largest profit margin? - How can I earn extra money with my small backyard aquaponic system? - Which type of aquaponic system - Media-Bed/Flood-and-Drain, Nutrient Film Technique (NFT), Raft System / Deep Water Culture (DWC) - is the most profitable? - What are the pros and cons to each of these types of aquaponic systems? - In addition to selling your harvest, are you aware of all the other ways in which you can earn revenue from your aquaponic system? - How much time would I need to invest to have an aquaponic system that will feed my family and provide us with some extra income? This user-friendly easy to read book will answer the above a questions. This valuable resources is also packed with the necessary information that will not only show you how to make extra money with your aquaponic system, but to grow it into a successful commercial business; if that is your desire. Also included are two real-world aquaponic business plans. This book is an excellent investment that will reward you greatly with the knowledge needed to earn extra money through aquaponics or optimize revenue from a commercial aquaponic operation._x000D_ Table of contents :- _x000D_
