 Eelgrass in New York's South Shore Bays: An Assessment from the 

 Literature," Special Report No. 13, Reference 78-1, Marine Sciences 

 Research Center, State University of New York, Stony Brook, 1978. 



This report covers all published and unpublished information available on 

 the distributions of surficial sediments and eelgrass iZosteva mavirwi) in New 

 York's south shore bays. Graphical and tabular summaries of sediment texture 

 and eelgrass cover are presented.

 Depth," Journal of Wildlife Management, Vol. 30, No. 2, 1966, pp 280-285. 



The growth of eelgrass {Zosteva marina) in relation to tidal depth was 

 studied at three areas of Humboldt Bay, California. Six contours of bay 

 bottom between +1.0 and -1.5 feet in relation to mean lower low water (MLLW) 

 datum were sampled. The upper limit of eelgrass growth was at or slightly 

 above +1.0 foot. This isobath was exposed to air about 15 percent of the 

 time. The percent of eelgrass coverage, mean turion length, and eelgrass bio- 

 mass all increased with increases in water depth. The density per square foot 

 and the number of leaves per turion did not vary with depth. The optimum 

 depth for eelgrass production was about -1.0 foot. More than 90 percent of 

 the biomass and about 60 to 70 percent of the eelgrass acreage in south 

 Humboldt Bay occur at or below MLLW.

 vival of Turtle Grass, Thalassia testudinwn, in Boca Ciega Bay, Florida," 

 Fishery Bulletin, Vol. 69, No. 2, Apr. 1971, pp. 273-280. 



Turtlegrass was transplanted to an unvegetated, dredged canal and a hand- 

 cleared part of a flourishing grass bed. Complete or partial success was 

 attained in 7 of 14 planting methods used. The best method, in which short 

 shoots (rhizomes removed) were dipped in a solution of plant hormone (naph- 

 thalene acetic acid) and attached to construction rods for transplanting, was 

 100 percent successful and may be suitable for general application.

 Zostera rmrina L. Effect of Substrate on Growth," Aquaaulture , Vol. 12, 

 No. 3, Nov. 1977, pp. 197-213. 



Eelgrass {Zostera marina) is an important component of the temperate 

 coastal ecosystem. The effect of different substrate types on Z. marina 

 growth was studied using transplants of individual shoots and rhizomes. The 

 new leaves formed the most reliable parameter for relative production. Trans- 

 plants originating from a natural silt environment displayed best overall 

 growth. Plants grown in a silt substrate continually afforded better growth. 

 The quality of the sediment was also examined. Plants grown in undisturbed 

 natural sediments were more successful than plants in sediments which were 

 disturbed. Aspects of the physiology and ecology of Z. marina are discussed 

 with reference to the substrate.
