Ecological Potentiality of Plankton: A Perspective on Nutrition, Toxicity and Bio-Indication

The base of aquatic energy is initiated and concreted by plankton such as primary photosynthetic algae and consequently their immediate secondary grazers as zooplankton. The nutritional features of algae or phytoplankton are controlled by aquatic nutrients (e.g. nitrogen, phosphorus, silica and other essential minerals). Moreover, the biochemical content of zooplankton reflects their diet profiles (e.g. bacteria and algae). The promising and sustainable fisheries prospects are crucially subjective by nutritional quality and quantity of plankton (e.g. algal bloom). Additionally, both algae and zooplankton are efficient as auspicious biological tools for indicating the aquatic environments.

Does the Marine Stewardship Council's Eco-labelling Scheme Require Sustainable Fisheries Management?: a Study of the Marine Stewardship Council's Objections Procedure

<p>The Marine Stewardship Council eco-labelling scheme was formed in order to provide a means of promoting sustainable fisheries that moved away from conventional top-down management. In order to remain robust and transparent, MSC allows stakeholders to object to a certification through an objections process outlined by MSC. Over the past 15 years, this objections process has come under increasing scrutiny. The MSC OP has been accused of Ambiguous wording, principal agent issues and an unequal judicial process by some stakeholders and outside commentators. These accusations pose a real threat to the reputation of the MSC. If left un-addressed, MSC’s credibility amongst consumers and academics has the potential to be lost. This thesis seeks to investigate the legitimacy and robustness of the MSC OP. There is a focus on the way in which the MSC OP facilitates interactions between objection actors, influences actors, and how each actor is empowered by the MSC OP methodology.</p>

Analysis of primary productivity and trophic status of Kuala Gigieng waters Aceh Besar for sustainable fisheries management

Kuala Gigieng is one of the estuary areas in Aceh Besar Regency. This research is about the analysis of chlorophyll-a and trophic status of Kuala Gigieng waters in the context of sustainable fisheries management. This research was conducted in April 2019 in the water of Kuala Gigieng. This study aims to determine the trophic status of the waters, the value of chlorophyll-a and the abundance of phytoplankton in the Kuala Gigieng waters. Determination of observation stations using random stratified sampling method. Analysis of chlorophyll-a using the Trichomatic method. Analysis of the trophic status of the waters with the Trix method. The results showed that the waters of Kuala Gigieng were categorized as high fertility (eutrophic). The value of chlorophyll-a ranged from 0.21 u.g/l - 5.56 ug/l, and the value of net primary productivity (NPP) ranged from 3.47-27.77 mgC/m3/hour and the value of gross primary productivity (GPP) ranged from 5.20-32.98 mgC/m3/hour. Meanwhile, the abundance of plankton ranged from 133.33-207.40 ind/l. Water quality parameters are still suitable for the growth of plankton in Kuala Gigieng waters.

Preface

Pandemic COVID-19 has hardly impacted global fisheries and aquaculture, as FAO reported in the 34th session of the Committee on Fisheries (COFI) in February 2021. FAO further suggests that this pandemic impact catalyzes the fisheries sector to be more innovative, socially, and environmentally responsible. Fish and fisheries products are well-known healthy food. It contains high quality and quantity of protein and provides essential vitamins and minerals to maintain human health status. The innovation of science and technology in the fisheries sector is a crucial point to improve and assure the efficiency and sustainability of the production and utilization of the resource. Research activities and development should be synergically conducted to implement technologies that benefit the communities. Department of Fisheries, Faculty of Agriculture, Universitas Gadjah Mada, holds a biennially international symposium to provide access and exchange of research data and fisheries experience to support the transfer of knowledge and technology to strengthen the world’s fisheries sector. The 4th International Symposium on Marine and Fisheries Research (The 4th ISMFR) aims to bring together academic scientists, researchers, government institutions, private parties, and stakeholders to share and exchange progress information, experiences, and research results in all aspects of marine and fisheries sciences. The 4th ISMFR theme was promoting sustainable fisheries through technology and research innovation for a healthy community”. It covered a broad spectrum of fisheries-related topics, including aquaculture, fish disease, fish genetics, biotechnology, marine natural product, seafood processing technology, seafood safety, fisheries biology, fisheries resources management, fisheries socio-economics, oceanography, climate sciences, and marine ecotoxicology. Due to the Pandemic COVID-19, the 4th ISMFR was held virtual on July 28-29, 2021, by using the Zoom Meeting platform. We cannot postpone this symposium because it is a routine schedule for researchers and stakeholders to disseminate and discuss their research findings. The seminar’s organizing committee was located in the Fisheries Department, Faculty of Agriculture, Gadjah Mada University, Yogyakarta, Indonesia. Management of the symposium was carried out using the website (http://ismfr-ugm.org/). The symposium consists of a plenary session and parallel presentation sessions. The plenary session presented three keynote speakers, namely Professor Rashid Sumaila from The University of British Columbia (Canada), Professor Erlinda R. Cruz Lacierda from The University of the Philippines Visayas (Philippines), and Professor Soottawat Benjakul from The Prince of Songkla University (Thailand). A total of six parallel presentation sessions was conducted with 12 invited speakers and presenters from eight countries, namely Norway, Belgium, New Zealand, Japan, Australia, Thailand, Malaysia, and Indonesia. Presentations in each parallel class were divided into presentation panels consisting of approximately five presenters. Each presenter was given 10 minutes for presentation and discussion. Discussion sessions were held at the end of each forum for about 15 minutes. A total of 146 scientific papers have been presented at the 4th ISMFR. The 4th ISMFR was attended by 155 participants. All presenters and attendances join the symposium virtually from their respective residences. Readers can access recordings of the 4th ISMFR Plenary session on the YouTube channel (https://www.youtube.com/watch?v=dGtjnoR3hSo&t=7599s). This proceeding provides an opportunity for readers to gain more information from the reviewed papers that have been presented in the 4th ISMFR. The articles published in this proceeding were selected from the papers presented in the symposium. The reviewers from six countries (Philippines, Egypt, Malaysia, Thailand, Japan, Indonesia) and the editors from four countries (Malaysia, Thailand, Japan, Indonesia) have participated in the abstracts screening, improving, and finalizing the manuscripts. The proceedings divided into three sections, namely aquaculture, aquatic resource management, and fish product technology. From this proceeding, readers will find recent research finding on broad aspects of fisheries and marine sciences to come up with new knowledge and idea to promote sustainable fisheries through technology and research innovation for a healthy community.

Management of sustainable fisheries and utilization status of red snapper (Lutjanus spp.) using handline landed in archipelagic fishing port of Brondong

Fish resources of the study were landed in the Archipelagic Fishing Port of Brondong and it is dominated by the demersal fish (bottom). The red snapper (Lutjanus spp.) is one of demersal fish that is found in the Archipelagic Fishing port of Brondong. There is a catch on the red snapper (Lutjanus spp.) that takes place continuously without good management. This condition can impact to the decline or fullness of the number of its population, it is necessary to have a review to suspect the potential of sustainable catch and the number of total allowable catch, and the number of total allowable efforts in the management of the sustainable fishing commodity of red snapper (Lutjanus spp.). The data analysis method used is the production surplus model. The result of this research showed that the potential for maximum sustainable catch (YMSY) is 102.88 tons/year and total allowable catch (TAC) is 82.31 tons/year. Maximum sustainable effort (fMSY) is 709 trips/year and total allowable effort is 242 trips/year. utilization rate is 75% where condition in status fully exploited.
