Available in PDF, EPUB and Kindle. Book excerpt: "This study's primary goal was to understand the oceanographic effects on larval crab transport and distribution between an estuarine inner and more oceanic outer bay in the subarctic estuary of Kachemak Bay, Alaska. Plankton tows and hydrographic measurements (temperature and salinity) were taken along the boundary between the two bay parts from March - October on spring and neap tides. Summer water flow and in Kachemak Bay is predominantly freshwater-driven and density patterns vary inter-annually with the amount of freshwater supplied to the inner bay. Larvae of seven crab species occurred in a seasonal sequence and the crab larval assemblage was closely correlated to temperature in the upper 20 m. The influence of tidal forcing on larval transport was not clear even though most species exhibited peak abundances at spring tides. Larval distribution patterns across the inner/outer boundary indicated that Oregonia gracilis larvae may be transported into inner Kachemak Bay; however, late larval stages of the two commercially relevant species, Chionoecetes bairdi and Cancer magister, were never observed and may be exported from the inner estuary. These observations provide an important baseline for further studies to understand Kachemak Bay's role as a source or sink for larval crab"--Leaf iii.

This book was released on 2007 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Larval, juvenile, and adult crab distribution was surveyed in three different habitats in Kachemak Bay, Alaska from June 2005 to September 2006 to determine temporal and spatial variability. Crab distribution varied temporally and spatially in all life stages. Nine sites of varying habitat complexity were surveyed monthly using scuba, light traps, and shrimp pots to measure habitat variables, quantify larval, juvenile, and adult crabs, and survey potential crab predators. No single bay-wide variable determined the appearance of all crab larvae. Spatial differences in larval abundance probably resulted from large scale physical transport mechanisms. Overall juvenile and adult crab abundance increased with habitat complexity; however species richness was not positively correlated with complexity. This study suggested that the canopy structure provided by Nereocystis luetkeana had minimal effects on spatial crab distribution in all life stages. Canopy structure may not influence the spatial distribution of larval crabs and is thought to have little importance for juvenile and adult crabs. Understory kelp density may more directly affect juvenile and adult crabs by providing more microhabitats for refuge. Habitat use and the importance of structural complexity vary by life history stage and species depending on survival strategy"--Leaf iii.

Book Synopsis Spatial Variation and Evidence for Multiple Transport Pathways for Dungeness Crab (Cancer Magister) Late-stage Larvae in Southeastern Alaska by : Quinn T. Smith

Smith and published by . This book was released on 2008 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Time series of larval abundance collected with light traps reveal large pulses of Dungeness crab (Cancer magister) late-stage larvae (megalopae) in Glacier Bay, with high variability among years. Because it is unclear whether processes affecting larval supply in Glacier Bay are broadly applicable to the larger region of southeastern Alaska, and whether larval abundances inside a marine reserve are different from areas with commercial fishing, I investigated megalopae abundance in the surrounding region. Megalopae abundances in Berner's Bay, 60 km further inland was 56 times smaller than the Glacier Bay site. In 2006, I increased the geographic extent of sampling along a 350 km gradient from the outer coast to the inside waters. I found that Glacier Bay had, on average, five times more megalopae than other sites. A 2-D tidal circulation model suggests a circulation barrier east of Glacier Bay. Morphometric differences in megalopae suggest a difference in larval size on either side of the barrier, indicating that larvae may have multiple transport pathways into inside waters. In summary, C. magister megalopae abundance in southeastern Alaska is highly spatially variable; circulation patterns in southeastern Alaska are complex, and multiple transport pathways for early stages of C. magister are likely"--Leaf iii.

This book was released on 2007 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mixing, loss, and distribution of larval Dungeness crabs were investigated inside and outside of Glacier Bay, southeastern Alaska, biweekly from late May to mid-September and monthly in Icy Strait from late May to late August in 2004. Larvae were collected from two different portions of the water column: above and below the thermocline and at four stations in Icy Strait. Larval loss was markedly high for ZI, ZIV, and ZV, and relatively low for ZII and ZIII. ZI occurred from late May to late July. Larval stages progressed seasonally from ZI to ZV and density decreased from ZI through ZV. The larval densities at the inner and outer bay stations and at the shallow and deep depths were similar.
