Compared to similarly sized fish, mammals and birds typically have brain sizes fifteen times larger, though some species of fish such as elephantnose fish have very large brain-to-body ratios. However, fish still display intelligence that cannot be explained through Pavlovian and operant conditioning, such as reversal learning, novel obstacle ...
Fish are ranked on a numeric scale from 0 to 10. 10 is the highest score for newly-caught fish, 7 is in the neutral range, 6 is at the 'borderline', and fish scoring of 3 or lower is considered spoiled. [1] Customers will generally reject fish when its Torry score is 6 or lower, which indicates that the fish has been on ice for 11 days or more. [1]
Fish stocks indicators, which is normalized as a 0–100 proximity-to-target score, with 100 representing "at target" and 0 being furthest from the target. Stock assessments provide fisheries managers with the information that is used in the regulation of a fish stock. Biological and fisheries data are collected in a stock assessment.

Aristotle (ca. 340 B.C.) may have been the first scientist to speculate on the use of hard parts of fishes to determine age, stating in Historica Animalium that “the age of a scaly fish may be told by the size and hardness of its scales.” [4] However, it was not until the development of the microscope that more detailed studies were performed on the structure of scales.

Animal intelligence is the study about the origins of animal intelligence by studying the mental processes of other species. The basic premise of this research is that we need to understand the processes of association and learning in other animals in order to understand how human culture, art, religion, mathematics and more may have developed.
The general factor of intelligence, or g factor, is a psychometric construct that summarizes the correlations observed between an individual's scores on various measures of cognitive abilities. It has been suggested that g is related to evolutionary life histories and the evolution of intelligence [ 131 ] as well as to social learning and ...
Patrol vessels may do visual or electronic surveillance of fishing vessels at sea, or may board them for spot inspections. Fisheries management vessels also may independently monitor fish densities in the areas of interest, water conditions, or other observations of interest for operations or research.
