Texas—Inexpensive Pond Management Apps


The Texas A&M AgriLife Extension Service has release six new pond-management apps for Apple’s IOS7 operating system (iPhone, iPad and iPod Touch).  Dr. Todd Sink, AgriLife’s Extension Fisheries Specialist in College Station, Texas, provided the leadership for the development of the apps, which are available at Apple’s iTunes Store.


The links below will take you to a page with more information on each app.  To purchase one of the apps, click on the blue link that says “View In iTunes”, which is under the Texas A&M logo near the top on the left hand side of the page.  Then, on the page that appears, click on the “Buy” link under the Texas A&M logo.


AmmoniaCalc ($1.99) allows the user to input simple, easily measured water chemistry measurements such as pH and temperature to instantly calculate ammonia concentration.  Ammonia is the major end product in the breakdown of proteins.  Over time, the buildup of ammonia can kill shrimp.


PondCalc ($1.99) allows the user to quickly and easily calculate the surface area of any shaped pond and then calculate the number of acre-feet, all without having to do any math.  The calculations allow the user to determine accurate pond area and volume for the application of chemical treatments and herbicides, with no fear of over or under estimating the amounts required.


AquaPlant ($5.99) is designed to help pond owners identify and manage aquatic vegetation.  After identification of the aquatic plant is achieved with the visual index and description pages, the user can then use the management section for each species to learn the correct treatment options including biological, mechanical and herbicide controls.


AquaRef ($0.99) is a quick reference guide featuring tables and conversion factors for aquaculture professionals.  The app has useful information that includes pond filling time, pumping rate equivalents, discharge rates from standpipes, net mesh sizes for grading fish, length/weight relationships for fish, oxygen saturation points, pounds of fish that can be hauled at various temperatures, egg development stages, stocking guides and fertilization rates.


AquaCide ($2.99) is an aquatic herbicide selection, effectiveness and restriction guide for pond managers.  It’s meant to help users select the most effective herbicides for all aquatic vegetation classes, including the most common North American algae and floating, submerged and emergent aquatic vegetation.  Only herbicides that provide good or excellent control are provided for each species.  The app also provides the environmental restrictions of all aquatically labeled herbicides, including those for human use such as drinking, swimming and fish consumption, as well as livestock watering, irrigation of turf and crops and other general restrictions and differences in formulation.


Texas Farm Pond Management Calendar ($1.99) is a virtual pocket guide/calendar to keep pond managers up to date with the activities needed during each month of the year in order to manage their ponds.  The calendar may be used to determine the appropriate time to do activities such as stocking, liming, fertilizing, harvesting, weed control, drawdown, feeding and renovation.
