摘要:
The dome (suction) sampler is a self-contained unit that consists of five main parts: (i) a transparent acrylic hemisphere to enclose an area of the river bottom; (ii) a bilge pump to vacuum organisms out of the sampler; (iii) a net to collect organisms as they are pumped out; (iv) a bag for collecting large stones; and (v) a band to seal the space between the dome and the substrate.

摘要:
Regression equations were developed between standard length (SL) and total length (TL) for Brevoortia patronus, Anchoa mitchilli, and Micropogon undulatus taken from Galveston Bay, Texas. The standard length-total length conversion equation for B. patronus was TL = 0.62044 + 1.25323 SL, and for A. mitchilli it was TL = 0.22391 + 1.20634 SL. The conversion equations for M. undulatus changed with body length: TL = 1.21592 + 1.26753 SL (for fish 28-95 mm SL); TL = 9.70548 + 1.17538 SL (for fish 102-159 mm SL); and TL = 19.88505 + 1.10952 SL (for fish 168–255 mm SL).

摘要:
During a one-year marine ichthyofaunal study of Northport, New York, only one abnormal fish was taken, a striped bass, Morone saxatilis. This 3-year-old fish, lacking a lower jaw and part of the upper, was apparently injured between its second and third year of life, as evidenced by much reduced scale formation during that period. The fish, measuring 260 mm standard length and weighing 291.1 grams, was much smaller than normal fish of comparable age, being nearer the size of 2-year-old fish. This stunted growth was presumably due to reduced feeding ability resulting from the injury.
