For research purposes medium-sized fishing trawlers converted for pelagic longlining were used. Recent data inventory accounted about 130 research, searching, and fishing pelagic longline cruises for 1961- 1989 targeted tunas (generally Thunnus), billfishes (Makaira, Tetrapturus, Xiphias gladius), pelagic sharks (Carcharhinus, Isurus, Alopias, Prionace glauca, Galeocerdo cuvier). Other pelagic species were recorded as bycatch. More than 5200 longline sets with about 2.5 millions nominal hooks were shot. For every research cruise the following data were colleted on set by set basis: number of hooks, hooks distribution by depth, total catch, and catch by species. Almost all the fish caught were measured, weighed, and analyzed. Estimated catch depth of every fish was recorded. Environmental data and MBT station data generally available. Due to lack of computer equipment and limited funding throughout years of data sampling this valuable data were stored on paper as logbooks of longline catches and biological analysis.

  • Briefing on Human Trafficking in the Intl Fishing Industry
    December 19, 2016 BRIEFING ON GREENPEACE’S REPORT ‘TURN THE TIDE’ AND CENTER FOR AMERICAN PROGRESS’ REPORT ‘SEAFOOD SLAVERY: HUMAN TRAFFICKING IN THE INTERNATIONAL FISHING INDUSTRY’ TURN THE TIDE Summary In December 2016, Greenpeace released ‘Turn the Tide’, a year-long investigation into human rights abuses and illegal fishing in Thailand’s distant water fishing fleet. In the report, Greenpeace alleges that recent crackdowns on illegal fishing in Indonesia and Papua New Guinea forced offending vessels into the Saya de Malha bank area, a large, shallow, biodiverse tropical ecosystem. Due to inadequate enforcement in Saya de Malha – regulated by Mauritius and the Seychelles – Greenpeace claims that illegal fishing and human rights abuses have flourished. Greenpeace monitored the activity of large refrigerated fishing vessels (also known as “reefers”) in Saya de Malha from 2015 to 2016. Greenpeace alleges that there, beyond enforcement, instances of illegal fishing, human rights, and labor abuses occur on vessels. Abuses documented by Greenpeace include 22 hour workdays, a lack of employment contracts, lying about the cost of documents such as passports, and other violations. Unfortunately, Greenpeace also found that – once the vessel returns to port in Thailand – inspections by the Royal Thai Navy may not adequately identify potential trafficking victims due to coercive tactics by senior crew on these vessels. In addition to the aforementioned abuses, Greenpeace found other health risks present for fishers. The vessels monitored by Greenpeace are able to stay out at sea for months or years at a time in part due to transshipment, a practice in which a reefer supplies the vessel with food, fuel, and other supplies.

  • Fisheries Research
    1. Fisheries Research 1.1 Coastal (artisanal) fishery The monitoring of the artisanal fishery for the island of Mauritius was pursued and data on catch, effort, fish species and gear type were collected. Out of the 61 fish landing stations, around 25 fish landing stations were randomly selected on a monthly basis for data collection. 1.1.1 Catch, effort and catch per fisherman day The estimated total production was 950 tonnes of fresh fish comprising 579 tonnes from the lagoon and 371 tonnes from off-lagoon areas. The catch from the lagoon was slightly higher compared to last year whereas that of the off-lagoon showed a slight decrease and the overall mean catch per fisherman-day (CPFD) increased from 4.1 to 4.4 kg with a corresponding decrease in fisherman days. Table 1.1, Figure 1.1 and 1.2 show the catch, number of fisherman days and CPFD.

Duncan2 and Robert B. Hargraves3 ABSTRACT Concordant plateau and isochron ages were calculated from 40Ar/39Ar incremental heating experiments on volcanic rocks recovered by drilling at four Leg 115 sites and two industry wells along the volcanic lineament connecting Reunion Island to the Deccan flood basalts, western Indian Ocean. The new ages provide unequivocal evidence that volcanic ac- tivity migrated southward along this sequence of linear ridges. The geometry and age distribution of volcanism are most compatible with origin above a stationary hotspot centered beneath Reunion. The hotspot became active with rapid eruption of the Deccan flood basalts, western India, and subsequent volcanic products record the northward motion of the Indian and African plates over the hotspot through Tertiary time. The radiometric ages are in general accord with basal biostratigraphic age estimates, although some adjustments in current magnetobiostratigraphic time scales may be required. INTRODUCTION Morgan (1981) proposed that young volcanic activity at the island of Reunion is the present manifestation of a stationary One of the remarkable features of the floor of the Indian hotspot that earlier produced the island of Mauritius, the vol- Ocean is the large number of elevated plateaus, banks, and canic ridge underlying much of the Mascarene Plateau, the Cha- ridges scattered throughout the basin.

The goal of the engagement was two-fold: 1) Review leading academic research on DWF Our goal was to understand current research agendas on DWF, and to solicit expert perspectives on the topic. 2) Assess the current state of knowledge on DWF Our goal was to aggregate the known body of knowledge on DWF, specifically attempting to answer the following research questions: • What are the known impacts on the health of global fisheries from DWF? What are the known intersections between DWF and overfishing? • What is known about current trends in the growth, size, distribution, and affiliation of DWFs? • Where have investments and supporting subsidies been most significant? • How are distant water fishing nations investing in fisheries development in the Global South? • What are the links between these investments and fishing access agreements? • What are the known intersections between DWF and IUU fishing? • What are the known intersections between DWF and worker exploitation? The end product is this Synthesis Report aggregating the material CEA has uncovered, based on research undertaken between January and June of 2018.

    1. Fisheries Research 1.1 Coastal (artisanal) fishery Data from the artisanal fishery were collected on a monthly basis at 25 selected fish landing stations to estimate the catch and effort by fish species and gear type. During the year, 3 766 landings were thus recorded. 1.1.1 Catch, effort and catch per fisherman day The production of fresh fish was estimated at 682 tonnes and comprised 367 tonnes from the lagoon and 315 tonnes from off-lagoon areas. Compared to 2007, the estimated catch from both the lagoon and off lagoon increased by 42 tonnes mainly on account of good weather conditions prevailing during the month of December. The average catch per fisherman-day (CPFD) for the lagoon and off-lagoon areas was 5.6kg and was higher than that in 2007.
