AB  - The slowing of growth as fish age has long been believed to be related to energy 
      expenditure for maturation, and this rationalization has been used to explain 
      why, across nearly all fish species, the relationship between size at first 
      maturity (L(m) ) and maximum (L(max) ) or asymptotic length (L(infinity) ) is relatively 
      constant. In contrast, the Gill-Oxygen Limitation Theory (GOLT) postulates that 
      (a) fish growth slows because as they grow, their two-dimensional ability to 
      extract oxygen from the water diminishes relative to their three-dimensional 
      weight gain, and (b) they can only invest energy for maturation if oxygen supply 
      at their size at first maturity (Q(m) ) exceeds that needed for maintenance 
      metabolism (Q(infinity) ). It has been reported previously across dozens of marine fish 
      species that the relationship between Q(m) and Q(infinity) is linear and, further, it 
      can be mathematically converted to L(m) vs. L(infinity) by raising both terms to the 
      power of D (the gill surface factor), resulting in a slope of 1.36. If the GOLT 
      is universal, a similar slope should exist for L(m) (D) vs. L(infinity) (D) 
      relationships for freshwater species across multiple individual populations that 
      reside in disparate habitats, although to our knowledge this has never been 
      evaluated. For analysis, we used existing data from previous studies conducted on 
      51 stream-dwelling populations of redband trout Oncorhynchus mykiss gairdneri, 
      Yellowstone cutthroat trout O. clarkii bouvieri and mountain whitefish Prosopium 
      williamsoni. The resulting L(m) (D) vs. L(infinity) (D) slopes combining all data points 
      (1.35) or for all species considered separately (range = 1.29-1.40) were indeed 
      equivalent to the slope originally produced for the marine species from which the 
      GOLT-derived relationship was first reported. We briefly discuss select papers 
      both supporting and resisting various aspects of the GOLT, note that it could 
      potentially explain shrinking sizes of marine fish, and call for more concerted 
      research efforts combining laboratory and field expertise in fish growth 
      research.
