Results of Jack Mackerel tagging study, 1971-75

2021
Methods and materials used to tag and recapture jack mackerel, Trachurus symmetricus, off the coast of southern Ca1ifornia and Baja California, Mexico, are described. Tagging, recapture, and movement data resulting from this program are reported. Analysis of these data indicates substantial movement of jack mackerel within the range of the California ...

Results of the jack mackerel subpopulation discrimination feasibility study

2021
A report is made on the feasibility of discriminating subpopulations of jack mackerel, Trachurus symmetricus, off of the southern California and Baja California coast. Histochemical, morphometric, and meristic characters are compared from four samples of approximately 200 fish each taken from three areas.

A status report on the Jack Mackerel tagging program

2021
Methods and materials used to tag and recapture jack mackerel, Trachurus symmetricus, off the coast of southern California and Baja California, Mexico, are described. Tagging, recapture, and movement data resulting from this program are reported. Analysis of this preliminary data indicates a seasonal inshore-offshore movement pattern for this species ...

Blue jack mackerel (Trachurus picturatus) in Subdivision Xa2 (Azores)

2022
This  is  the  first  time  that  ICES  analyses  data  for  Trachurus  picturatus  in  the  waters  of  the  Azores.  The  lpue  indices  show  increasing  trends,  but  the  exploitation  status  is  unknown,  therefore  on  the  basis  of  precautionary considerations, catches should not be allowed to increase.

Communication of velocity changes in jack mackerel (Trachurus symmetricus) schools

Animal Behaviour, 1969
Abstract The latency and the velocity of the response of jack mackerel, T. symmetricus , to a velocity change by a schooling companion was studied in the laboratory. Fish were tested in groups of two and six fish each. One fish in each group was given an electric shock; the responses of the other fish in the group to the increase in speed by the ...
