GPP Retirement Party

In 1981, Smith-Root announced in the American Fisheries Society Fisheries Bulletin the very first model of the Generator Powered Pulsator, or more commonly called the GPP. It is with both sadness and excitement that we announce the retirement of the amazing GPPs. Over the last 38 years, GPP electrofishers provided you with the capability and confidence to conduct your critically important aquatic resource management and conservation research. Subsequently, we anticipate that many of you will continue to use GPP electrofishers for years to come because of the quality of craftsmanship…

Smith-Root Designs Solar-Powered Electric Barrier to Preserve Critically Endangered Mudfish Habitat in New Zealand

The Canterbury Regional Council recently completed construction on the first pulsed DC electrical barrier in New Zealand. The electrical barrier is designed to deter upstream movement of Brown Trout from the Hororata River into a tributary that contains one of the largest populations of the Canterbury Mudfish, a native fish that has a conservation status of Threatened (Nationally Critical) under the New Zealand Threat Classification System. The Canterbury mudfish (Neochanna burrowsius) is native to New Zealand and, as the name implies, is endemic to the Canterbury Plain south of…

Salmon & Trout Spawning and Biosecurity Workshop

Smith-Root scientists recently attended the Salmon & Trout Spawning and Biosecurity Workshop (Pendleton, OR) as well as the Northwest Fish Culture Conference (Portland, OR) to present exciting results from their recent publication in the Journal of Aquatic Animal Health. The study—led by Smith-Root researchers, Phong Nguyen (M.S.) and Austen Thomas (Ph.D) and conducted at the University of Idaho’s Aquaculture Research Institute—focused on the rapid detection and monitoring of bacteria directly from fish-rearing water. Their findings showed that the Biomeme field molecular…

Saving the Canterbury Mudfish

Five species of endemic mudfish are found in New Zealand, and they are all threatened or endangered.  The fish have a unique life history that allow them to live for months at a time burrowed into the stream bed while they wait for rains to fill the slow meandering streams they occupy.  The problem they face is those same habitats they need for survival are also heavily used for farming practices.  Additionally, the fish face pressures from non-native sport fish encroaching on the limited habitats they have left and preying on mudfish. Conservation agencies and land owners in New…
