Size-related Hooking Mortality of Incidentally Caught Chinook Salmon, Oncorhynchus tshawytscha

Mortality associated with the incidental catch and release by commercial trollers of two size classes of chinook salmon, Oncorhynchus tshawytscha, was assessed. Observed cumulative mortality 4-6 days after hooking was 18.3 percent for sublegal-sizefish « 66 cm FL) and 19.0 percent for legal-sizefish. Size of fish was not significantly related to mortality; however, when the results were combined with data from a previous experiment, there was a significant inverse relationship between fish length and mortality. Hooking mortality estimates calculated from tagging experiments and observed relative mortality of legal-and sublegal-size fish held in net pens, were used to derive a range for total hooking mortality of 22.0-26.4 percent for sublegal-size chinook salmon and 18.5-26.4 percent for legal-size chinook salmon

Chum salmon

Historically pink and chum salmon likely have always been the most abundant salmon species in the Gulf of Alaska (GOA). Factors accounting for this include biology requiring less extensive freshwater life history that affords opportunities for producing large numbers of juveniles. Most GOA pink and chum salmon originate from many regions throughout Alaska and British Columbia. Not all, however, originate from North America. Some Eas

Patient Tolerability with Office Transperineal Biopsy Using a Reusable Needle Guide

INTRODUCTION: Transrectal ultrasound-guided (TRUS) prostate biopsy is associated with a 1-5% risk of severe sepsis, despite the use of prophylactic antibiotics. Recent studies have demonstrated the feasibility of transperineal (TP) prostate biopsy in the outpatient setting under local anesthetic (LA). We demonstrate the safety, efficacy, and tolerability of our technique for performing TP biopsy under LA in the clinic setting using a reusable needle guide. MATERIALS & METHODS: A biplanar ultrasound probe with an attached adjustable, reusable needle guide was evaluated for transperineal biopsy. A 17 gauge x 10 cm coaxial needle is attached to the needle guide. The skin is infiltrated, bilaterally, approximately 2 cm anterolateral to the anal verge with 1% lidocaine using a 25 gauge needle. A deeper prostatic block is then performed using a 20 gauge spinal needle. Administration of the anesthetic is delivered to the musculature of the pelvic floor, superficial-to-deep. Prostate samples are obtained using an 18 gauge x 25cm biopsy gun. All biopsies on a side can be obtained utilizing a single perineal skin puncture site. Patients who underwent office TP biopsy after May 2019 also completed a 10-item patient experience questionnaire regarding pain or discomfort experienced during the procedure. RESULTS: In 2019, a total of 74 patients underwent office TP prostate biopsy under local anesthesia using a reusable needle guide, while 564 underwent office TRUS biopsy. Prostate biopsy was positive for malignancy in 58.1% of TP patients vs 57.6% in TRUS patients (p=0.93). TP biopsy had a lower utilization of prophylactic antibiotics compared to TRUS biopsy: 33.8% vs 99.5% (p\u3c0.001), yet there were no admissions, UTI, or sepsis for TP patients, compared to 6 admissions (1.1%) for TRUS biopsy (p=0.01)). The mean VAS score ± SD for pain or discomfort caused by the overall office TP biopsy was 3.68 ± 1.96. CONCLUSION: We demonstrate that office TP biopsy under LA with a reusable needle guide can be safely introduced with equivalent cancer detection rates whilst nearly eliminating the risk of urinary sepsis. This was achieved while also significantly reducing the use of prophylactic antibiotics. The procedure was well tolerated, with the most common complaint being local infiltration of anesthetic. We believe that office TP biopsy under LA can be performed with good patient tolerability, as almost 94% of patients were willing to undergo the procedure again. There is also the potential for reduction in overall cost with the use of a reusable needle guide
