From Preface: "Fish constitute, according to the highest authorities of the present time, not only a wholesome and nourishing food for man, but fish-diet is even declared necessary for the welfare of the human body. According to recent researches made under the auspices of the Smithsonian Institution, a pound of Herring, Salmon or Whitefish is equal, in nourishing qualities, to a pound of the best fresh beef. In the presence of this fact, fish can not be looked upon as a luxury, and fish-culture has as important a mission to fulfill as cattle-raising." This book contains 120+ recipes.
