The study was conducted to analyze the fish landings from Iraqi artisanal marine fisheries, northwest Arabian Gulf from January 2017 to December 2019. The monthly data of fish landings were collected from the main landing site at Al-Fao port, south Iraq and were analyzed using descriptive statistics. A total of 35 taxa in 18 families were identified in the artisanal catches, in addition to two species of shrimps. The highest total landings were 11,944 t in 2018 and 11,305 t in 2019. The annual total landing of the marine fisheries increased by 270% during 2017-2019 as compared with the annual landing during 2008-2016. Threadfin bream contributed 14.1%, followed by river shad (11.1%) and mullets (11.1%), whereas shrimps formed 15.2% to the total catch. The overall values of biomass diversity of fish ranged from 1.82 in 2017 to 2.85 in 2018. There were 320 registered fishing boats motorized by 65 to 950 hp. Multi gears fishing were observed. The trends of the landings of all fish groups were increased substantially, except river shad, threadfin bream and shrimps. The study suggests some of the management measures must be put into place, especially for the river shad in the regions of their migration reproductive and the nursery.

The promotion of pole-and-line fishery for a selective gear operating in the Indonesian tuna management area is considered as the proper policy in response to the increasing market demand with tuna eco-labeled. Appropriate information in addressing the current status of the pole-and-line fishery in Indonesia is an important step in order to support the promotion. Data used to describe the fishery were obtained through scientific port sampling program in collaboration between RCFMC and WCPFC in 2010 to 2014 and also scientific observer onboard program collaboration RCFMC and CRAC Co. Ltd. in 2013. The results show that presently the number of pole and line fleets was decreased significantly and remain about 232 fleetsin Sorong, Bitung and Kendari and Larantuka. The national annual total catch of pole-and line during 1980 – 2013 was recorded between 24,000 and 160,000 tons per year (average 98,117 tons per year). This value is estimated to contribute about 20% of Indonesia annual total catch of tuna in FMAs713-717. The pole-andline catch rates based at Bitung, Kendari and Sorong were fluctuated in each year with the range respective between 8.79 and 17.93 tons/trip/vessel, 4.78 and 5.36 ton/trip/vessel and about 7,99 ton ton/trip/vessel. Pole-and-line fishery operated in Indonesian FMAs 713-717 is considered as selective fishery, with > 80 % catches of skipjack in matured stage. The tuna-live bait fish ratio in Indonesian pole-and-line was 4.41 :1, then an improvement of live bait ratio as well as its management is required.

Abstract Because of the increasing oil industry development in the Arabian Gulf, hundreds of oil and gas facilities have been installed in both offshore and inshore areas during the last few decades. However, no studies have been conducted till now on the influence of these platforms on the structure and composition of marine faunal assemblages. The present work addresses this issue to propose environmental management measures connected to the utilization of fishery resources. Offshore and inshore surveys were carried out along the Saudi Gulf waters using trawl and beach-seine nets, respectively. Data relative to only fish (offshore) and fish and invertebrates (inshore) were collected concurrently with several factors: density of oil and gas facilities (offshore), distance to the nearest coastal platform (inshore), oceanographic variables, and habitat characteristics. Results of offshore surveys indicated higher fish density—both total and of fishery resources—in locations with a higher number of oil and gas facilities within a 5 km radius, whereas biomass density was not significantly different. Hence, oil and gas facilities seem to serve as nursery areas for small fish. For inshore communities, more species and diversity were found in stations closer to coastal oil and gas facilities. In addition, among the five coastal embayments sampled, those with more oil and gas facilities had more species. The findings of the present work support the hypothesis of a positive net ecological role of oil and gas platforms of the Saudi Arabian Gulf, with the implication that this effect could be extended to improve the sustainability of important fishery resources.

This study describes shore-based competitive fishing events in Ilhéus, southern Bahia (Brazil), including catch composition, and provides information on the profile of recreational fishers participating in these events. Information was collected in all events promoted by the Clube de Pesca de Ilhéus (CLUPESIL) in 2007-2008. A total of 26 competitive fishing events were organized during this period, with 47 species caught. The top species were: Cathorops spixii, Menticirrhus littoralis, Trachinotus goodei, Eucinostomus melanopterus, Polydactylus virginicus, Atherinella brasiliensis, and Eucinostomus argenteus. These seven species represented 87% of the total catch in number and 78% in weight. Menticirrhus littoralis and Polydactylus virginicus are species of commercial interest and their catch was dominated by juveniles. Local recreational fishers were predominately middle-aged men, who tended to use small hooks and mainly shrimp as bait. They were consumption-oriented, but also released small fishes. During competitions, fishers used even smaller hooks. Most of them perceived shrimp trawling as the main factor affecting recreational fisheries. The use of larger hooks and a minimum size of 20 cm are suggested to decrease the capture of juveniles, mainly those of commercial importance. This study sets a baseline from which new studies can be proposed to access the current status of local recreational fisheries.

Pollution problem has become a major social problem, and its existence affects the quality of our life and limits a higher level of economic development. How to better control pollutions has become a more serious practical problem before us. In this paper, firstly, it analyzes the advantages and disadvantages of main pollution control measures in the aspects of sewage charges, tradable discharge permit system, subsidies and mandatory technique and so on, and then describes the basic policy of environmental protection, pointing out that the performance of the environmental management policies and systems shows more and more in adaptation and gap, in which not only the environmental economic policies and systems are not perfect, with a low environmental efficiency, but also the entire environmental management system does not meet the needs of the current situation. Finally, it aims at the current status of pollution control in China, through a multi-perspective analysis of improvement measures in the hope of helping the pollution control in China.

Autoregressive Conditional Heteroscedasticity

Tourism receipts have important policy implications for destination countries in terms of government revenues and the management of tourism-related policies. This article uses time series models to analyse the risk exposure reflected in the growth rates of tourism revenues. To do so, we apply risk management measures based on value-at-risk (VaR) and the expected shortfall (ES), analysing monthly data for six Spanish regions from January 2004 to March 2017. Two main results were obtained. Firstly, tourism receipt growth rates present negative long-range dependence. In other words, they have intermediate memory or anti-persistence and therefore show signs of dependence between widely separated observations. Moreover, we detected the existence of long-range dependence in these volatilities in one of the six regions considered. Secondly, we show that VaR based on Generalized Autoregressive Conditional Heteroscedasticity (GARCH)-type models is a valid means of analysing the risk exposure of tourism receipt growth rates, doing so by evaluating various in-sample and out-of-sample VaR thresholds and the ES.

Ecosystem approach to fisheries (EAF) framework has assumed an important position within the broader management strategies of harvesting and managing marine fisheries without compromising the integrity and health of marine ecosystems. The EAF concept, embedded in many international instruments, is a testament of a growing recognition of the need to adopt a more holistic approach in fisheries governance by the international community. Attaining the full effect of the EAF framework would require States to have political will to implement this framework. With this in mind, this chapter analyses the extent to which Malaysia has adopted EAF framework for its marine fisheries management. It begins by examining the principles and management measures under international fisheries instruments regarding the EAF. It includes discussion of why the global community recognizes the EAF regime. Most significantly, Malaysia's national policy and legislative frameworks vis-à-vis the EAF principles and measures are also analyzed. This chapter recommends policy and legal reforms to address the gaps relevant to the implementation of EAF.

The aim of the study is to investigate university faculty members’ views towards adoption of cloud computing in higher education. The current status of the faculty on cloud computing usage in education and regional differences were discussed. Strengths, Weaknesses, Opportunities, Threats (SWOT) and Technology, Organization, Environment (TOE) frameworks were integrated. The data was collected through an adopted questionnaire based on these frameworks and demographic information were answered by 300 faculty members from north parts of Cyprus and Iraq. This study is exploratory and causal comparative which descriptive statistics with independent t-test were used to analyse data. The results showed that faculty members agreed mostly on the opportunities which followed by awareness of potential threats and weaknesses and lastly they accept the strengths of adopting cloud computing in education. They are highly in consensus on technological availability followed by organizational aspects and lastly on environment related regulations. Regional difference exists in the sub-dimension of TOE. Faculty members from north part of Cyprus agreed more upon the relative advantage of using cloud computing as compared to their counterparts. The study brought light on the comprehension of faculty members’ views from comparative and integrated framework perspectives.
