Dear Mr. Dibbern,
Thank you for posting your request on History Hub!
We searched the Records of the Bureau of Naval Personnel (Record Group 24) and located deck logs of the USS Chivo (SS-341) from 28 April 1945, when it was commissioned by the Navy, to 1 July 1971 when it was decommissioned. We also located deck logs of the USS Bluefish (SS-222) from 24 May 1943, when it was commissioned by the Navy, to 12 February 1947 when it was first decommissioned and from 7 February 1952 when it was recommissioned to 20 November 1953 when it was decommissioned for the last time. For access to and copies of these records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org.
We hope this information is helpful. Best of luck with your research!
