SUSTAINABLE FISHERIES and RESPONSIBLE AQUACULTURE: a Guide for USAID Staff and Partners
SUSTAINABLE FISHERIES AND RESPONSIBLE AQUACULTURE: A Guide for USAID Staff and Partners June 2013 ABOUT THIS GUIDE GOAL This guide provides basic information on how to design programs to reform capture fisheries (also referred to as “wild” fisheries) and aquaculture sectors to ensure sound and effective development, environmental sustainability, economic profitability, and social responsibility. To achieve these objectives, this document focuses on ways to reduce the threats to biodiversity and ecosystem productivity through improved governance and more integrated planning and management practices. In the face of food insecurity, global climate change, and increasing population pressures, it is imperative that development programs help to maintain ecosystem resilience and the multiple goods and services that ecosystems provide. Conserving biodiversity and ecosystem functions are central to maintaining ecosystem integrity, health, and productivity. The intent of the guide is not to suggest that fisheries and aquaculture are interchangeable: these sectors are unique although linked. The world cannot afford to neglect global fisheries and expect aquaculture to fill that void. Global food security will not be achievable without reversing the decline of fisheries, restoring fisheries productivity, and moving towards more environmentally friendly and responsible aquaculture. There is a need for reform in both fisheries and aquaculture to reduce their environmental and social impacts. USAID’s experience has shown that well-designed programs can reform capture fisheries management, reducing threats to biodiversity while leading to increased productivity, incomes, and livelihoods. Agency programs have focused on an ecosystem-based approach to management in conjunction with improved governance, secure tenure and access to resources, and the application of modern management practices. -
A Global Database for Metacommunity Ecology, Integrating Species, Traits
www.nature.com/scientificdata There are amendments to this paper OPEN A global database for DATA DescRIPTOR metacommunity ecology, integrating species, traits, environment and space Alienor Jeliazkov et al.# The use of functional information in the form of species traits plays an important role in explaining biodiversity patterns and responses to environmental changes. Although relationships between species composition, their traits, and the environment have been extensively studied on a case-by-case basis, results are variable, and it remains unclear how generalizable these relationships are across ecosystems, taxa and spatial scales. To address this gap, we collated 80 datasets from trait-based studies into a global database for metaCommunity Ecology: Species, Traits, Environment and Space; “CESTES”. Each dataset includes four matrices: species community abundances or presences/absences across multiple sites, species trait information, environmental variables and spatial coordinates of the sampling sites. The CESTES database is a live database: it will be maintained and expanded in the future as new datasets become available. By its harmonized structure, and the diversity of ecosystem types, taxonomic groups, and spatial scales it covers, the CESTES database provides an important opportunity for synthetic trait-based research in community ecology. Background & Summary A major challenge in ecology is to understand the processes underlying community assembly and biodiversity patterns across space1,2. Over the three last decades, trait-based research, by taking up this challenge, has drawn increasing interest3, in particular with the aim of predicting biodiversity response to environment. In community ecology, it has been equated to the ‘Holy Grail’ that would allow ecologists to approach the potential processes underlying metacommunity patterns4–7. -

Although a number of successful mitigation measures have been developed, the scope of the bycatch problem far exceeds our current capacity to deal with it. Specifically, we lack a comprehensive understanding of bycatch rates across species, fisheries, and ocean basins, and, with few exceptions, we lack data on demographic responses to bycatch or the in situ effectiveness of existing mitigation measures. As an introduction to this theme section of Endangered Species Research ‘Fisheries bycatch: problems and solutions’, we focus on 5 bycatch-related questions that require research attention, building on exam- ples from the current literature and the contributions to this Theme Section. -

Flood Pulse and Aquatic Habitat Dynamics of the Sentarum Floodplain Lakes Area
Flood Pulse and Aquatic Habitat Dynamics of The Sentarum Floodplain Lakes Area H. Hidayat a,*, Siti Aisyah a, Riky Kurniawan a, Iwan Ridwansyah a, Octavianto Samir a, a Gadis Sri Haryani a Research Center for Limnology-LIPI; Kompleks LIPI Cibinong, Jalan Raya Bogor, Km. 46, Cibinong 16911; *[email protected] Received 29 November 2020 Accepted 13 December 2020 Published 17 December 2020 Abstract The Lake Sentarum is a complex of floodplain lakes in the middle part of the Kapuas River system in West Kalimantan, Indonesia. The area has a great ecological and economic importance, however, the Sentarum lakes complex and its catchment area are generally threatened by deforestation, fire, monoculture agroindustry, and pollution.The objective of this research is to establish the hydrological characteristics of the Sentarum lakes area and to reveal the dynamics of aquatic habitat resulted from changing water levels. Data were collected during our field campaigns of 2013-2017 representing the seasons. The water level was measured using a pressure sensor placed at the Lake Sentarum National Park resort, while rainfall data were obtained from the data portal of the Tropical Rainfall Measuring Mission. Inundation monitoring was carried out using a time-lapse camera. A hydrological model is used to simulate water levels beyond measurement period. Water quality and fish sampling were carried out at the lake area. Vegetation observation was carried out at the selected riparian zone of the lake area using the line transect method. Water level records show that the Sentarum floodplain lakes have two peaks of inundation period following the bimodal pattern of rainfall in the equatorial Kapuas catchment. -
Other Processes Regulating Ecosystem Productivity and Fish Production in the Western Indian Ocean Andrew Bakun, Claude Ray, and Salvador Lluch-Cota
CoaStalUpwellinO' and Other Processes Regulating Ecosystem Productivity and Fish Production in the Western Indian Ocean Andrew Bakun, Claude Ray, and Salvador Lluch-Cota Abstract /1 Theseasonal intensity of wind-induced coastal upwelling in the western Indian Ocean is investigated. The upwelling off Northeast Somalia stands out as the dominant upwelling feature in the region, producing by far the strongest seasonal upwelling pulse that exists as a; regular feature in any ocean on our planet. It is surmised that the productive pelagic fish habitat off Southwest India may owe its particularly favorable attributes to coastal trapped wave propagation originating in a region of very strong wind-driven offshore trans port near the southern extremity of the Indian Subcontinent. Effects of relatively mild austral summer upwelling that occurs in certain coastal ecosystems of the southern hemi sphere may be suppressed by the effects of intense onshore transport impacting these areas during the opposite (SW Monsoon) period. An explanation for the extreme paucity of fish landings, as well as for the unusually high production of oceanic (tuna) fisheries relative to coastal fisheries, is sought in the extremely dissipative nature of the physical systems of the region. In this respect, it appears that the Gulf of Aden and some areas within the Mozambique Channel could act as important retention areas and sources of i "see6stock" for maintenance of the function and dillersitv of the lamer reoional biolooical , !I ecosystems. 103 104 large Marine EcosySlIlms ofthe Indian Ocean - .

ICELAND, WHALING and ECOSYSTEM - BASED FISHERY MANAGEMENT
ICELAND, WHALING and ECOSYSTEM - BASED FISHERY MANAGEMENT PETER CORKERON Iceland, whaling and ecosystem-based fishery management. Peter Corkeron Ph.D. http://aleakage.blogspot.com/ 1 Introduction Icelanders look to the sea, and always have. Fishing has always been important to them, and they have a good record of attempting to ensure that their fisheries are sustainable. As the Icelandic Ministry of Fisheries stated in a declaration on 17th October 2006, “The Icelandic economy is overwhelmingly dependent on the utilisation of living marine resources in the ocean around the country. The sustainability of the utilisation is therefore of central importance for the long-term well being of the Icelandic people. For this reason, Iceland places great emphasis on effective management of fisheries and on scientific research on all the components of the marine ecosystem. At a time when many fish stocks around the world are declining, or even depleted, Iceland's marine resources are generally in a healthy state, because of this emphasis. The annual catch quotas for fishing and whaling are based on recommendations by scientists, who regularly monitor the status of stocks, thus ensuring that the activity is sustainable.”. Fisheries account for approximately 40% of the value of Iceland’s exported goods and exported services, and roughly two-thirds of Iceland's exported goods, minus services. Fisheries and fish processing account for little under 10% of Iceland’s Gross Domestic Product (GDP), down from more than 15% in 1980. With a population of just over 300,000 in 2007, Iceland is the world’s 178th largest nation, but in 2002 it was still ranked as the world’s 13th largest fisheries exporter. -

60 Years of Coral Reef Fish Ecology: Past, Present, Future
BULLETIN OF MARINE SCIENCE. 87(4):727–765. 2011 CORAL REEF PAPER http://dx.doi.org/10.5343/bms.2010.1055 60 YEARS OF CORAL REEF FISH ECOLOGY: PAST, PRESENT, FUTURE Mark A Hixon ABSTRACT Revisiting the past 60 yrs of studies of the ecology of fishes on coral reefs reveals successive decadal trends that highlight many lasting contributions relevant to fisheries biology, conservation biology, and ecology in general. The Bulletin of Marine Science was founded in 1951, about the same time SCUBA was first used to study reef fishes, so the 1950s was a decade of initial subtidal exploration by early pioneers. Detailed natural-history investigations of the use of space, food, and time by reef fishes developed in the 1960s, including studies based from undersea habitats late that decade. The 1970s saw the first comprehensive observational studies of reef- fish communities, as well as initial breakthroughs in behavioral ecology, especially regarding cleaning symbiosis, mating systems, and sex reversal. In community ecology, the conventional wisdom—that interspecific competition structured reef-fish assemblages via equilibrium dynamics and resource partitioning—was called into question by the “lottery hypothesis,” which posited that coexistence of ecologically similar species was fostered by nonequilibrial dynamics. The 1980s, in turn, were dominated by debate regarding the relative importance of larval supply vs post-settlement interactions in determining the local abundance and diversity of reef fishes. The “recruitment limitation hypothesis” asserted that larval settlement was so low that subsequent population dynamics were not only unpredictable, but also density-independent. Population and community studies during the 1990s thus focused largely on detecting demographic density dependence in reef-fish populations and identifying the mechanisms underlying this ultimate source of population regulation.
