The Warnbro Sound Crab Fishery Draft Management Plan., Fiona Crowe

Fisheries Management Papers

In recent years fishing effort for the blue summer/manna crabs (Portunus pelagicus) in Warnbro Sound has increased dramatically and concerns have been raised about the state of stocks of crabs in Warnbro Sound. As a result of the increased pressure being put on the limited resource, the relationship between professional and recreational user groups has become sensitive. It is therefore appropriate that measures ensure the responsible management of the Warnbro Sound Crab Fishery be introduced. Gear, bag limit and size restrictions on the taking of blue swimmer crabs by recreational fishermen already exists as part of the the overall recreational …

Rock Lobster Industry Advisory Commitee Chairman's Report, October 1994 - The Western Rock Lobster Fishery - Management Proposals For The 1994/95 And 1995/96 Seasons, Rock Lobster Industry Advisory Committee, Peter Rogers

Fisheries Management Papers

The failures of past restrictions on fishing effort to fully halt the decline of the breeding stock led to the formation of a sub-committee of the Rock Lobster Industry Advisory Committee. The prime objective of the sub-committee is to evaluate effective long term strategies for managing the fishery so that breeding stock is maintained at an adequate level despite the inevitable increases in catching efficiency. The purpose of this report is firstly to advise industry of the management proposals for the 1994/95 seasons and secondly to form a basis for industry consultation on management arrangements for the 1995/96 season.

Long Term Management Strategies For The Western Rock Lobster Fishery (4 Volumes) - A Market-Based Economic Assessment For The Western Rock Lobster Industry (May 1994) (Volume 3), Marec Pty Ltd

Fisheries Management Papers

In October 1992 a special Sub-Committee of the Rock Lobster Industry Advisory Committee was set up to consider and evaluate future management strategies for the rock lobster fishery. Pursuant to this the Director of Fisheries commissioned a marketing study that is the basis of this report. This study was commenced in early October 1993 and completed in May 1994. This study looked at the market implications of fishery's management strategies. In particular it assesses how the existing management structure limits the potential for the lobster industry to maximise the financial return, and in doing so provides an insight into the …

Long Term Management Strategies For The Western Rock Lobster Industry (4 Volumes) - Economic Efficiency Of Alternative Input And Output Based Management Systems In The Western Rock Lobster Fishery (Volume 2), Bob Lindner

Fisheries Management Papers

Since 1965, the Western Rock Lobster Fishery has been managed by what is essentially a license limitation scheme invoiving restricted entry for boats, and strict controls on the aggregate number of pots which can be used by the commercial fishing sector. By most measures, management of this fishery has been highly successful. Biological over-exploitation of the fish stock has been prevented, at least until recently. Notwithstanding these achievements, there is widespread concern that the future profitability, and even the viability of the industry is under threat unless the current management practices are reformed. Because of the complexity and intrinsic uncertainty …

Seasonal Composition Of Mesozooplankton In The Pagan River, A Nutrient Enriched Virginia Estuary, Lillian Norman Davis

Biological Sciences Theses & Dissertations

A two year study of the mesozooplankton composition and seasonal distribution was conducted in the Pagan River, a nutrient rich tidal estuary and tributary to the lower James River. The mesozooplankton was dominated by calanoid copepods (80%), with the total zooplankton abundance peaks occurring during spring and fall. The total mean abundance, 3008/m', was somewhat lower than those found by other authors, however the mean abundance at one station approximated those means. Seventy-eight percent of the calanoid copepods were Acartia spp. that were primarily responsible for the fall increase in mesozooplankton abundance. The spring increase was primarily due to increases …

Eutrophication And Macrobenthic Communities Of The Lower Chesapeake Bay: Effects Of Organic Enrichment In Pocomoke Sound, Saxis Virginia, Janice D. Mcdonnell

Biological Sciences Theses & Dissertations

The effects of organic enrichment on benthic community structure were evaluated in a field study conducted in Pocomoke Sound in the vicinity of a seafood processing plant. The empirically derived Species Abundance and Biomass (SAB) curves of Pearson and Rosenberg (1978) were used to model patterns of organic enrichment at the study site, called Pig Point, as well as two reference sites located within Pocomoke Sound. The Split Moving Windows (SMW) method was used to detect the ecotone point as defined in the Pearson and Rosenberg (1978) model and the Two Term Local Quadrat Variance (TTLQV) method was used to …

Open Corridors In A Heavily Forested Landscape: Impact On Shrubland And Forest-Interior Birds, Robert A. Askins

Biology Faculty Publications

In eastern North America, remnant patches of forest surrounded by open habitat constitute unfavorable habitat for many species of migratory forest birds because of high rates of nest predation and cowbird parasitism. Although most evidence for this relationship comes from 'forest islands' surrounded by residential or agricultural land, even forest patches isolated from other forests by narrow open corridors such as roads and powerline rights-of-way seem to show this pattern. Productive habitat for migratory birds can be maintained by consolidating corridors and routing them along the periphery of forests to retain as much continuous forest as possible. Consolidation of open …

Benthic Community Responses To Hypoxic Conditions In The Lower Rappahannock River, Virginia, Mary Elaine Smith

Biological Sciences Theses & Dissertations

The effects of seasonal low dissolved oxygen conditions upon benthic macroinvertebrate communities were studied in the lower Rappahannock River, a tributary of the Chesapeake Bay. Benthic communities were sampled during March, June, August, and September 1993 at five equidistant depths (5, 10, 15, 20, and 25 m) extending upwards from the deepwater Virginia Benthic Biological Monitoring Station LE3.4 located in the deep basin just inside the mouth of the Rappahannock River. Infaunal species diversity, richness, biomass, and density were measured along with the vertical depth distribution of organisms within the sediment. Significant sediment differences were found between the shallowest, 5 …

The Effect Of Climate And Spittlebug (Aeneolamia Albofasciata) On Buffelgrass (Cenchrus Ciliaris L.) Productivity In The Sonoran Desert, Martha H. Martin-Rivera

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I conducted field studies during 1984-1988 to determine how (1) precipitation amount and distribution affect buffelgrass [Cenchrus ciliaris L. (Link) l productivity, (2) summer rainfall amount and distribution and temperature influenced the spittlebug (Aeneolamia albofasciata Lalleman) life cycle, and (3) summer burning affects spittlebug densities and buffelgrass productivity.

Experiment I was conducted from 1985 through 1988. Forage samples collected at 15-day intervals were separated into live, recent-dead standing, old-dead standing, and litter. There was a positive relationship between the summer precipitation and the live biomass. Recent-dead standing and old-dead standing decomposed during the summer, fall, or spring.

The Relationship Between Creep Feeding Behavior Of Piglets And Adaptation To Weaning: Effect Of Diet Quality, David Fraser, J. J.R. Feddes, E. A. Pajor

Feeding Behavior Collection

Individual variation in creep feed intake and its relation to adaptation to weaning were studied in piglets weaned at 4 wk of age. The animals received either a "low-complexity" creep-starter diet based on corn, barley and soybean meal (12 litters), or a "high-complexity", medicated, commercial diet without soybean meal (12 litters). Diets were fed as creep feed during the 2 wk before weaning, and as the sole diet during the 2 wk after weaning. Creep feeding behavior of piglets was monitored by video recording. Pigs fed the high-complexity diet consumed more creep feed (P < 0.05), tended to gain more during the week before weaning (P < 0.10), and converted feed more efficiently and gained more weight in the 2 wk after weaning (P < 0.01). Use of creep feed varied greatly among individual littermates. Multiple regression analysis showed that on the high-complexity diet, pigs that used creep feed more than their littermates tended to be those with low gains in weeks 1-3 after birth (P < 0.001), and tended to gain more weight during the week before and during the 2 wk after weaning (P < 0.01). The trends were consistent but weaker with the low-complexity diet. However, predictive power was low, with creep feeding accounting for only 4% of individual variation in post-weaning gain on the high-complexity diet and 1% on the low. Regardless of diet quality, therefore, creep feeding remained highly variable and only weakly related to weight gains during the 2 wk after weaning.

The Effects Of Requiring Different Response Strategies Following Caching In Clark’S Nutcrackers (Nucifraga Columbiana), Alan Kamil, Russell P. Balda, Deborah J. Olson

Papers in Behavior in Biological Sciences

Clark’s nutcrackers use spatial memory to recover stored food in the field and have performed very well in laboratory tests of spatial memory. During the present experiment, two groups of nutcrackers cached seeds every 4 days. Following each cache session, the stay group was tested with seeds in their caches; the shift group found seeds in novel sites. The stay group performed accurately throughout the experiment, but the shift group gave no indication of being able to learn to avoid sites where they had stored seeds. These results suggest that although nutcrackers can learn to shift away from remembered locations …

Utilization Of Wood Duck Nest Boxes With Respect To Plant Community Type, Orientation And Juxtaposition At The Green Bottom Wildlife Management Area, West Virginia, Anthony Benjamin Borda Jr.

Theses, Dissertations and Capstones

Utilization of wood duck (Aix sponsa, L.) nest boxes was evaluated at the Green Bottom Wildlife Management Area, a 1,110-acre mid-Ohio Valley floodplain. Primary focus was directed upon nest box utilization by the wood duck but use by other wildlife was observed and recorded. Utilization of the nest boxes by the wood duck was analyzed with respect to plant community type, orientation and juxtaposition to other wood duck nest boxes. Forty-three wood duck next boxes were observed and inspected in 1993. Wood ducks nested in 24 of the nest boxes, and 361 eggs were found. Clutch size ranged …

The Ohlone And The Oak Woodlands: Cultural Adaptation In The Santa Clara Valley, Grant William Schick

Research Manuscript Series

Today, Santa Clara Valley consists of a modern industrialized environment distinguished by concrete, pavement and automobiles. These "innovations" made by modern technology began only recently. The environment and ecology of 200 years ago was extremely different from ours today. Filled with many native habitats, it thrived through the inter-dependance of all plant and animal species. In this study, I examine the characteristics of Santa Clara Valley in centuries past and today, in order to understand the vast number of resources which were available to the native inhabitants of the Santa Clara Basin. This paper has its base in cultural ecology, …

Effect Of Sewage Effluent On Bird Abundance And Species Composition In A Northern Minnesota Wetland, Joann M. Hanowski, Gerald J. Niemi

Journal of the Minnesota Academy of Science

Bird abundance was monitored before (1985 and 1987) and after (1989) sewage wastewater effluent was added to a northern Minnesota wetland. Community parameters (i.e., number of individuals and species richness) varied annually, but, overall bird communities in 1985 and 1989 were more similar to each other than they were to the 1987 community. Relative abundance of 35 bird species was unchanged between years and species abundance ranks were not different between years. Distribution of numbers of individuals (relative percent) within nesting and foraging guilds (species that have similar nesting or feeding requirements) was similar among years. Numbers of species that …

Predicting The Past, Recounting The Future: Human Ecology And A Prehistory Of Consciousness, Paul Faulstich

Pitzer Faculty Publications and Research

This paper is concerned with the organic derivation and primary meaning of Pleistocene finger flutings; I propose that in order to gain insight into the significance of the flutings, we must attempt an understanding of the physical and mental contexts in which they emerged. I suggest that finger flutings provided a cultural record in the Pleistocene which documented thought and action, and made it ready for reflection. Through the process of finger fluting, the human 'self' was objected and reality was modified in the experience of self-consciuosness. I argue that finger flutings, like language, were employed to discover and convey …
