This past spring, Cedar Creek Corrections Center and the Sustainable Prisons Project began experimenting with a new captive rearing project to raise crickets.  The goal of the project is to create a more sustainable, stable supply of food to meet the demand created by housing a growing population of endangered Oregon Spotted Frogs. Crickets are one of the largest expenses for the frog project. Cricket suppliers are located out of state.  Long-distance shipping complications can impact frog feeding schedules, and definitely increase the project’s carbon footprint. As a result of these issues, the offenders at CCCC decided they would try their hand at cricket husbandry and breeding.

Few organizations in Washington raise their own crickets. Most suppliers, including pet shops, purchase crickets from out of state breeders.  By locally-growing crickets for the Oregon Spotted Frog conservation project, SPP offenders and staff are taking another step toward creating a more sustainable, cost effective, and stable food supply.

Inmates and scientists are discovering best practices for rearing crickets.

The Project is also contributing to scientific knowledge, compiling best practices protocol for raising crickets in temperate climates through trial-and-error experimentation. While visiting with offenders to check on how things have progressed, SPP Research Associate Jill Cooper was impressed to see how much the offenders had learned through observation and experience, in such a short amount of time. One inmate explained to her how the current batch of “breeders” that were delivered to the prison, “aren’t really the age which the cricket farm said they are.”  He pointed to the “ovipositor” or egg-depositing tube noting that they were obviously under developed and not ready to lay eggs yet.  Crickets chirp to indicate when they are ready to breed.  The inmate is considering starting his own cricket farm when he is released to offer a more sustainable source of crickets to customers here in the northwest.

Training Officer Ron Gagliardo of Amphibian Ark recently made a visit to CCCC to advise inmates and staff on the cricket rearing operation.  Previously from the Atlanta area, Ron has extensive experience with frog and cricket rearing.  He was a tremendous resource.  The inmates were able to ask him many questions and his input will undoubtedly improve upon the initial success of the cricket operation.

There have been many bumps along the way, but things have been looking up for the cricket operation.  Offenders are able to raise crickets to help supplement the frog’s diet, and have learned much in the process. While the cricket project can not yet support all the food needs, we estimate that the current operation will eventually support at least half of the crickets needed to feed about 200 frogs.
