Mangrove species are uniquely adapted to tropical and subtropical coasts, and although relatively low in number of species, mangrove forests provide at least US $1.6 billion each year in ecosystem services and support coastal livelihoods worldwide. Globally, mangrove areas are declining rapidly as they are cleared for coastal development and aquaculture and logged for timber and fuel production. Little is known about the effects of mangrove area loss on individual mangrove species and local or regional populations. To address this gap, species-specific information on global distribution, population status, life history traits, and major threats were compiled for each of the …

Multi-Host Model-Based Identification Of Armillifer Agkistrodontis (Pentastomida), A New Zoonotic Parasite From China, Shao-Hong Chen, Qin Liu, Yong-Nian Zhang, Jia-Xu Chen, Hao Li, Ying Chen, Peter Steinmann, Xiao-Nong Zhou

Harold W. Manter Laboratory of Parasitology: Library Materials

Background: Pentastomiasis is a rare parasitic infection of humans. Pentastomids are dioecious obligate parasites requiring multiple hosts to complete their life cycle. Despite their worm-like appearance, they are commonly placed into a separate sub-class of the subphylum Crustacea, phylum Arthropoda. However, their systematic position is not uncontested and historically, they have been considered as a separate phylum.

Methodology/Principal Findings: An appraisal of Armillifer agkistrodontis was performed in terms of morphology and genetic identification after its lifecycle had been established in a multi-host model, that is, mice and rats as intermediate hosts, and snakes (Agkistrodon acutus and Python molurus) …

Shark Bay Prawn And Scallop Fisheries. Final Review Report, Department Of Fisheries Western Australia

Fisheries Management Papers

In recent times, the Department of Fisheries has received representations from both sectors about the ongoing interaction of the fisheries and their respective management settings. As a result, a decision was made to comprehensively review the fisheries, taking into account matters of fishery sustainability and gear interactions, together with industry economics and market considerations.

The review has also addressed research requirements to ensure an appropriate scientific basis for decision-making into the future.

Shark Bay Prawn And Scallop Fisheries: Final Review Report, Western Australia. Department Of Fisheries

Fisheries Management Papers

The Shark Bay Prawn Fishery and Shark Bay Scallop Fishery operate in the same general areas of Shark Bay (although there are some differences in their areas of operation). The interrelationship between trawling activities for the two target species (prawns and scallops) has raised both management challenges and industry conflicts over time. Harvest level settings for each fishery (in the form of effort levels and the timing and/or location of fishing) are independently set, on the basis of recruitment and abundance surveys of each target species. However, each industry sector strongly believes that the interactions between the fisheries arise because …

Fisheries Research Contract Reports

Ten Mile Brook Dam has a surface area of 275 Ha and receives water from a 10 km2 catchment (Figure 1). It has a total storage capacity of 1,691 ML. At the time of this study the dam was 89 % capacity (1,511 ML), however as recently as June 2009 water storage was as low as 663 ML (39 % capacity).

In order to improve the drinking water supply to the town of Margaret River, the Water Corporation is investigating the option of pumping bore water into Ten Mile Brook Dam. This would remove the need to transfer water from …

Risk Assessment Of Catch And Release, Rolf Erik Olsen, Tor Fredrik Næsje, Trygve Poppe, Lynne Sneddon, John Webb

Aquaculture and Fisheries Collection

The report was produced during most of 2009, and gives a state of art overview of current knowledge on the effects of catch and release practices on these fish species’ welfare, using accessible and peer reviewed published literature as basis for the assessment. Anecdotic and non-published reports have been used to a limited extent as they are regarded as untested or containing unverified statements. The Panel on Animal Health and Welfare discussed the full report in a meeting on the 9th of December, and gave its support to the conclusions drawn by the ad hoc-group.

The report has concentrated on …

Age, Growth And Maturation Of Swordtip Squid (Photololigo Edulis) In The Southern East China Sea, Kae-Yih Wang, Kuo-Tien Lee, Cheng-Hsin Liao

Journal of Marine Science and Technology–Taiwan

The reproductive biology, and age and growth of the swordtip squid (Photololigo edulis) in the East China Sea were examined based on the growth ring of statoliths from 1797 specimens during the period of November 2002 to November 2004. The maximum age observed was 261 days in female and 253 days in male, an evidence showing that swordtip squid has a longevity of about 9 months in both sexes. Growth in mantle length (ML) and body weight (BW) in both sexes was best described by the exponential model. There was significantly difference in somatic or statolith growth between the sexes. …

Passive Immunity To White Spot Syndrome Virus (Wssv) In Penaeus Monodon Treated With Monoclonal Antibodies Of The Heterologously Produced Vp28 Viral Envelope Protein, Jyh-Yih Chen, Kumarasamy Anbarasu, Chin-Yu Chen, Ying-Chuan Lee, Fan-Hua Nan, Ching-Ming Kuo

Journal of Marine Science and Technology–Taiwan

White spot syndrome virus (WSSV) is a highly pathogenic and prevalent virus affecting shrimp culture worldwide including Taiwan. In the present study, the viral envelope protein, VP28, gene of the WSSV was cloned into a pET28a expression vector. VP28 was expressed as a protein with a 6-histidine tag in Escherichia coli and purified by a Ni-NTA column. Antiserum was raised against this recombinant VP28 protein in BALB/C mice, and it recognized the VP28 protein in purified virions and recombinant proteins. The antiserum was mixed with arginine (100 ppm), lysine (168 ppm), and phenylalanine (88 ppm), and the titer of the …

Antioxidant And Immune-Stimulating Activities Of Hot-Water Extract From Seaweed Sargassum Hemiphyllum, Pai-An Hwang, Chwen-Herng Wu, Shu-Yun Gau, Shih-Yung Chien, Deng-Fwu Hwang

Journal of Marine Science and Technology–Taiwan

The hot-water extract of seaweed Sargassum hemiphyllum was evaluated antioxidant activity by using four different methods, including DPPH free radicals scavenging activity, Fe+2 chelating activity, superoxide anion radical scavenging activity and reducing power, and the immune-stimulating activity by using HB4C5 cells and J774.1 cells. It was found that the antioxidant activity was increasing in correlating with the concentration below 3.5 mg/ml. The HB4C5 cells showed the maximum relative activities of cell proliferation (174%) and IgM secretion (132%) at 120 µg/ml of hot-water extract. Overheating slightly reduced the immune-stimulating activity of hot-water extract. At 80 µg/ml, J774.1 cells showed the maximum …

The Efficacy Of Sanctuary Areas For The Management Of Fish Stocks And Biodiversity In Wa Waters, James W. Penn, Warrick J. Fletcher

Fisheries Research Reports

Debate concerning the relative benefits of marine protected areas (MPAs) for the management of marine resources can often reflect unrecognized differences in the scope, scale and definitions of the objectives being sought by various Government or community bodies. There can also be different opinions on the level of protection required for an area to be considered an ‘MPA’ and functional definitions for both the biological diversity and ecosystems within these areas are often lacking. This paper seeks to outline the relative efficiency and effectiveness of MPAs, especially no-take sanctuary areas, compared to other strategies currently employed to help achieve the …

The Influence Of Partial Timber Harvesting In Riparian Buffers On Macroinvertebrate And Fish Communities In Small Streams In Minnesota, Usa, Christopher J. Chizinski, Bruce Vondracek, Charles R. Blinn, Raymond M. Newman, Dickson M. Atuke, Keith Fredricks, Nathaniel A. Hemstad, Eric Merten, Nicholas Schlesser

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Relatively few evaluations of aquatic macroinvertebrate and fish communities have been published in peer-reviewed literature detailing the effect of varying residual basal area (RBA) after timber harvesting in riparian buffers. Our analysis investigated the effects of partial harvesting within riparian buffers on aquatic macroinvertebrate and fish communities in small streams from two experiments in northern Minnesota northern hardwood-aspen forests. Each experiment evaluated partial harvesting within riparian buffers. In both experiments, benthic macroinvertebrates and fish were collected 1 year prior to harvest and in each of 3 years after harvest. We observed interannual variation for the macroinvertebrate abundance, diversity and taxon …
