Brown slim is a common condition on the downwind side of many farm ponds this summer.

Brown slim is a common condition on the downwind side of many farm ponds this summer.

This is a common condition on the downwind side of many farm ponds this summer says Extension Wildlife and Fisheries Specialist Billy Higginbotham. Despite the recent rains, plankton blooms no doubt continued to die due to the heavy cloud deck over the past two weeks. Higginbotham took this photo to give pond owners a good idea of what the” oily, brown, foamy residue” some are finding in their ponds right now. Many fear that something ran into or was dumped into the pond. This condition may persist until water temps begin to drop in a few weeks. There is really no need to try and treat it.

This filmy residue is usually brown or reddish in color and is often accompanied by bubbles.  With our high water temperatures and lack of rain, we are seeing ponds change color—often daily. This is the result of bloom die-offs of phytoplankton and/or zooplankton with residue collecting on the downwind side of the pond.

There has not been a good, in-depth survey of producer issues with predation across Texas in many years. Without it, it can be hard to coordinate at a local, district, and regional level. 

This survey will look at what specific predation problems producers experience across Texas, what they are currently using as predation control techniques, and the economic burden on them. The goal is to produce a set of recommendations for when it is economically useful to exercise control, and what combination of methods to use. The researchers feel that this project has great value to the people of Texas, as well as the Texas A&M AgriLife Extension Service, as it will help us understand better, county-by-county, what the predation issues are, and how we can help address them. 

On our website you will find a fillable pdf, that means just tab through and click your response or type the information asked for, save it and then email the saved version back to me.  It should not take more than five minutes and  your email will be separated from the survey.

The survey is located at:

Thank you in advance.

Extension Wildlife and Fisheries Specialist Billy Higginbotham reports these overcast days with or without rain means no photosynthesis is occurring and oxygen is being depleted by fish populations, particularly in those ponds where the fish populations or at or near 1000 pounds per surface acre (that’s just 100 pounds in a 1/10 acre pond!). If pond owners  suspect a problem (e.g., catfish going off feed) to check their ponds at daylight—the time of day when oxygen levels are at their dead level lowest and if fish are “piping” at the surface they need to react quickly. . Running an outboard motor in a fixed position or using a pump to pull water from near the surface and spraying it back over the pond should help.

“Almost every week I hear questions from new landowners and folks who want to put a horse on a small acreage, says Tarrant County AgriLife Extension Agent Fred M. Hall. What kind of pasture should I grow? How Do I control Weeds? How many horse can I put on my new place? How do I control flies? These are difficult questions to answer and because each farmette is different. This program will share lots of information with new owners. It is set for 6 to &:30 p.m. on Tuesday, August 30 and will be held in the Bluebonnet Room in the Tarrant County Extension office. The office is located at 200 Taylor St., in Fort Worth.

U.S. corn production is forecast at a record 15.2 billion bushels, up 613 million from the July projection, according to USDA’s first survey-based corn yield forecast of the year.

Consequently, USDA slashed its projected range for the season-average corn price by 25 cents on both ends to $2.85 to $3.45 per bushel for the 2016/17 crop year.  This would be down 45 cents at the midpoint from the $3.55 to $3.65 per bushel range now expected for 2015/16.

Corn ending stocks for 2016/17 are projected 328 million bushels higher and, if realized, would be the highest since 1987/88.
