What is the growth rate of a marlin?

Excuse me, could you possibly clarify what you mean by the "growth rate of a marlin"? Are you referring to the rate at which a marlin fish grows in size over time, or perhaps you're inquiring about the potential growth or expansion of a company or organization named Marlin? If it's the former, the growth rate of a marlin fish can vary greatly depending on the specific species, diet, and environmental conditions. On the other hand, if you're asking about a company or organization, I would need more context to accurately answer your question. Could you please provide some additional details or clarification?
