A study of the fish populations within the surf zone and over the first and second reefs 

 off Hallandale (Broward County), Florida, was conducted 7 years after dredging for a beach 

 restoration project. This study utUized an observational and recording technique adapted 

 from Jones and Thompson (1978). The data were compared with those of an earlier study 

 conducted in 1971-72. 



In tlie 1971-72 study, conducted during and after dredging activities, 42 species of 

 fishes belonging to 24 families were found. The present study revealed the presence of 114 

 species of fishes belonging to 36 famihes. The dusky jawfish (Opistognathus whitehursti) , 

 common along the first reef platform in 1971-72, was absent. The absence of this fish is 

 attributed to an alteration of the substrate on the first reef by incursion of fine sediments. 

 Damage to the second reef observed during 1971-72 was not evident during this study.

This study examines the invertebrate and fish life associated with estuarine tidal 

 marshes located in SHetz and Netarts Bays, Oregon. Sweep nets, drift nets, corers, 

 enclosures, and clip plot samplers were used to collect botli quantitative and 

 nonquantitative samples of invertebrates in level marsh, pan, tidal creek, and tidal flat 

 habitats located in seven study areas representing a range of marsh types. Fish were sampled 

 by seine and otter trawl in these habitats as well as in a slough and in bay channels. The data 

 summarize the fauna of the various habitats and marsh types; fish stomach content data 

 show the food organisms of fish found in these habitats. Threespine sickleback and young 

 staghorn sculpin were most common throughout the marsh zone, whereas juvenile salmonids 

 and other species were found only over submerged level marshes and in a slough. Terrestrial 

 marsh invertebrates were consumed in modest amounts, wdth the greatest predation on tlie 

 aquatic crustaceans and worms. Future studies should examine the feeding habits of juvenile 

 salmonids inhabiting large tidal creeks and compare the feeding habits with those of similar 

 species found in other nearby habitats.

In A^t^r^O, experimental plots were estabhshed on a baymoutli bar at Nauset Harbor 

 on Cape wo d, Massachusetts. On the bar, botli sand fences and American beachgrass 

 (Ammophila breviligulata) were tested as alternative techniques for creating and stabilizing
