==Explanation==
{{incomplete|Created by a BOT EXECUTING REMOTE COD - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
{{w|Remote code execution}} is a type of {{w|software exploit}} that takes advantage of a bug to allow a remote user of a computer application to make it run code that it was not intended to execute. E.g. a webserver with such an exploit might allow a user of the web page to make it run a program that deletes system files or display private information.

The joke in this comic is that if you remove the "e" from "code", you get "remote cod execution". This refers to killing ("executing") codfish remotely, using an exploit in a network application that allows you to view the hatchery.

The title text contains a pun on {{w|rainbow tables}}, referring to {{w|rainbow trout}}, one type of which ({{w|steelhead}}) is {{w|anadromous fish|anadromous}} (migrating up rivers to spawn -- {{w|salmon}} are another well known example). These are used when trying to crack hashed passwords; it's simply a file with many possible passwords and their corresponding hash values. To prevent this, most modern password systems use "{{w|salt (cryptography)|salt}}", an extra random string that has been appended to the password before hashing, so the same password will have many potentially different hashes, and it becomes infeasible to store all of them in a file. An additional pun is that rivers contain fresh water, so there's no salt (the chemical/food additive kind) and the fish are more vulnerable to having their passwords cracked.

There is an additional pun on the phrase "shooting fish in a barrel", which could be taken figuratively to mean that the task is a "piece of cake", or that he is literally shooting fish. Black Hat, in addition to being a black hat hacker, might also be playing {{w|Call of Duty}} (CoD) and performing an execution in this shooter game.

{{w|Fish (Unix shell)|fish}} is also the name of a {{w|UNIX shell}}. Shells are popular targets for computer hackers as they are capable of running arbitrary commands.
