Abstract:
In the present paper, first 13 hull forms of fishing boats with different block coefficients were generated. Later, 26 hull forms of fishing boats with two different ratios of length to beam were generated by utilizing previous hull forms of fishing boats mentioned. In total, 39 fishing boats were generated. This series is called "Fishing Boats Series of ITU" (Istanbul Technical University). In this Series, the forms of the body stations and beams of the boats are the same for equal block coefficient and different lengths. The ratio of the beam of any station at any waterline to the beam of boat, Bz/B varies with respect to block coefficient, CB. These variations have been represented with the third-degree polynomials. Thus, a hull form of the fishing boat in the desired length and block coefficient can be obtained by using these polynomials. For this purpose, a computer program called "Turetme" was developed. Finally, by using this program, three hull forms of fishing boats were obtained and presented here.

Abstract:
A study was conducted to examine the technical efficiency for Setbag net fishing boats operated in the year 2014. A total of 100 samples of Setbag net fishing boats were selected, of which 40 were from Cox’s Bazar, 40 were from Chittagong and 20 were from Bagerhat. Stochastic frontier (with technical inefficiency effect) model was specified and estimated. Results have shown that the estimated mean technical efficiency of Setbag net fishing boats is 84 percent. The efficiency of Setbag net fishing boat was positively associated with total cost, while the number of nets were negatively related to fishing day and crew size. Head maji’s age had significant effect on inefficiency at 5% level. Although, the effect on boats’ efficiency was positive, (though insignificant) for head maji’s experience, head maji’s education, engine horse power and boat age. The use of modern fishing boat and improved fishing technology should be promoted, through proper training and motivation program for fisher. At the same time old and unfit fishing boat and gears should be gradually removed and replaced by new and modern fishing boat.The Agriculturists 2017; 15(2) 59-65

Abstract:
Conventional gasoline engine fishing boats have several disadvantages, such as high exhaust emissions, high fuel consumption, and low service life. The disadvantages of the gasoline engine can be resolved by using the electrical engine. Electrical fishing boats is an improvement on conventional boat to reduce the fuel consumption and emissions. In realizing an electric fishing boat, a feasibility analysis of the design, shape and weight that can be accommodated is required. The feasibility of an electric fishing boat has been successfully carried out by simulating the boat on Maxsurf Software. The aim of this research is to analyze feasibility of conventional boats by designing electric fishing boats. Improving feasibility is carried out by calculating hydrostatic forces and resistance. Electric fishing boats design using the simulation model in Maxsurf Modeller and simulation of resistance in Maxsurf Resistance at speeds of 1, 3 and 5 knots, with Wyman method. The modeling results show that the electric fishing boat design has a pointed front configuration with a V-shaped bottom. Main dimensions LoA 3.49 m, width 0.8 m; height 0.5 m; and a draft of 0.2 m, the boat produces a hydrostatic force which includes a displacement of 301.5 kg, a midship draft and submerged area of 0.2 m, a wet area of 3.08 m2, and a waterline of 0.5 – 1.5 m. Testing 1, 3, and 5 knots, the boat experienced resistance of 26.11 N, 234.96 N, and 652.73 N respectively. The power required for the boat to operate was 13,43 W, 362.66 W, and 1678,97 W. The feasibility of designing an electric fishing boat is the main key to developing an electric fishing boat.

Abstract:
Fishing boat laws in Korea require fishing boats to be equipped with a location transmitter. Approximately 91% of registered fishing boats have V-pass terminals, whereas those with a gross tonnage of 10 t or more have either V-pass or automatic identification system (AIS) terminals (or use both). Most navigators, including the fishing boat location transmitter, rely on the satellite signals provided by the global navigation satellite system (GNSS) without considering the accuracy of the navigation instruments that indicate ship location. Many scholars are conducting research to analyze the accuracy of GNSS locations through continuous experiments; however, few of them focus on fishing boat location transmitters. Particularly, the location accuracy of V-pass equipment is unknown. Notably, the V-pass and AIS terminals used in fishing boats are mainly designed to locate fishing boats in need of assistance following a marine accident rather than to provide information on approaching ships and preventing collisions. Therefore, this study aimed to compare GNSS location storage data extracted from the location transmitter (V-pass and AIS terminal) of the accident fishing boat with the DGPS location information from the Electronic Chart Display and Information System to check the position error and use it for accident analysis and investigation.

Abstract:
Fishing wealth is one of the richest resources in the Sultanate of Oman. It is considered as one of the most important economic developments that nation depends on in a larger way. The Sultanate of Oman is characterized by the presence of a large fishing fleet as the number of fishing vessels and boats in it. Good research with the application of modern technology in fishermen boats is required to increase the quality of fishing by providing fishermen with a safe and secure fishing experience. Artificial intelligence (AI) in boat automation technology is new and it is a mandatory demand for Oman’s fisheries sector. At the time of fishing, there are a lot of problems fishermen face such as weather changes, border tracking, navigation, illegal fishing, pirate attack, oil spill, technical fault in boats, etc. Therefore, the application of AI and related techniques in boat automation, information sharing, and preparation of documentation resources is very important in this sector. The main requirement for a fisherman is a high-quality fishing boat with proper communication devices to provide all the required information to fishermen and the control room. In this paper, a review has been made on fishermen’s boats with artificial intelligence for a sustainable fishing experience ensuring safety, security, navigation, and sharing information for Omani fishermen.

Abstract:
Considering unobserved spatial-temporal interaction effects, this study proposes a Bayesian spatial-temporal interaction model for predicting economic loss from fishing boat collisions using 10-year (2004–2014) collision records from six different areas in the waters of Fujian, China. Results show strong spatial heterogeneity and correlation effects in fishing boat collisions, while the economic loss from boat collisions gradually decreases with the time trend. Collision time, collision location, visibility and the involvement of LNG/LPG/chemical-carrying ships show similar marginal effects on the economic loss for the two collision types: fishing boat collisions and collisions involving no fishing boats. Navigational status and the involvement of cargo ships exhibit much bigger effects in fishing boat collisions compared with collisions involving no fishing boat. Unlike collisions involving no fishing boat, fishing boat collisions are associated with reduced economic loss in poor weather conditions characterised by strong wind/waves because in Fujian waters additional safety measures are adopted for fishing boats in such conditions. The proposed model is useful for policymakers in adopting safety enhancement strategies to decrease the economic loss resulting from fishing boat collisions.

Abstract:
Since fuel is a significant item in fishing operation, its high price becomes a burden for fishers and boat owners so they have to improve the economic efficiency of fishing operation. This study reviews the suitability of the dimensions of fishing boats with the power of the engine to determine a strategy in addressing an issue in fuel consumption. The suitability was assessed by comparing the existing engine power with the theoretical power required by the boats and the amount of fuel carried onboard during their fishing trips with the theoretical amount of fuel needed. The results showed that most small-sized boats at Palabuhanratu had engines with power more than the requirement, except for wooden boats that used 40 PK outboard motor engines. Fishers tend to carry fuel 62.1% more than the theoretical requirement because of the use of larger engines and the needs to bring spare fuel.

Abstract:
Fishing boats are equipped to quickly rescue ships and save lives in the event of an incident at sea; therefore, determination of the incident location is imperative for a swift response. According to the 2021 marine accidents by ship use statistics, fishing and non-fishing boats accounted for 64.6 and 35.4%, respectively, of the total 3053 ships involved in an accident. In addition to V-pass and the Automatic Identification System (AIS), several other types of terminals exist; however, approximately 91% of all registered fishing boats use V-pass terminals. Therefore, it is essential to know the exact location of fishing boats. However, little research has been conducted on V-pass equipment. Therefore, in this study, marine experiments were conducted using V-pass and AIS terminals that are mainly used in fishing boats. To determine the exact location of an incident and rapidly respond and rescue, this study compared the data saved in the terminals with the data received by the Vessel Traffic Service center. In the event of a maritime incident, the radio shadow areas and causes of the error in the location transmitter must be investigated to quickly rescue the fishing boat and to determine the root cause of the incident, respectively.

Abstract:
The development of boat technology and traditional fishing gear, which is still predominantly used by fishing communities in Indonesia, appears to be running slowly. This study aims to determine the adaptations and technological innovations that have been applied in fishing communities for the development of capture fisheries technology in Tomini Gulf. Data and information about fishing boats and fishing gear in the form of types, functions, sizes, structures, pictures, raw materials, and changes in shape, changes in function, as well as adaptations and technological innovations that occur are obtained by field surveys conducted in fishing villages. Other data were obtained through in-depth interviews with fishermen and community leaders using interview grid instruments. Adaptations and innovations that occur in fishing boats include the use of bodi hull types on ketinting (long-tail outboard engine) boats and the use of fiberglass and PVC (Polyvinyl chloride) pipe as substitutes for wood and bamboo as raw materials for hull and outrigger buoys. The lampu suntik (waterproof lamp of LED sircuit in a used syringe plastic tube) is an innovation made on the totabito squid fishing gear. Adaptation and innovation in fisheries technology occurs part-by-part (partial) and requires proving success to gain wide acceptance. Keywords: adaptation; innovation; techology; fishing boat; fishing gear; traditional.

Abstract:
The Irrawaddy dolphins, Orcaella brevirostris (Owen in Grey 1866) of Guimaras Strait, Philippines, have been known to utilize a core habitat within a coastal area surrounding the Bago River estuary in Negros Occidental. The dolphins’ close dependence on coastal waters often makes unavoidable direct interaction with human communities. Daily human activities in the coastal areas can pose serious threats to the dolphins, including high risk of entanglement in fishing nets, pollution, and disturbances caused by fishing boats and larger vessels. This study determined the behavior of dolphins toward different kinds of boats present in Bago-Pulupandan coastal waters. Factors identified to affect dolphin behavior towards boats include boat type (motorized or not), size, and distance from dolphins. Dolphin behavior towards boats were categorized as either positive, negative, or neutral. Results showed that the dolphins mostly exhibited neutral behavior towards boats, regardless of state and boat type. The dolphins’ passive behavior around vessels may make them more vulnerable to boat strikes, especially from speeding motorized boats. Recommendations include strict regulation of boat speed and traffic within their core habitat to minimize injuries, net entanglement, and avoid mortality.

Abstract:
Rising fuel costs and decreased catch sizes have reduced the fishing vessel owners profit margin. This has caused the owners to try to find methods that reduce the costs of their operations. In this thesis a tool which can be used by fishing vessel designers, and operators, is developed for use at the preliminary ship design stage. It is used to determine the best fishing vessel parameters for a given operational scenario found on the West Coast of Canada.

Abstract:
Motions and stability of a typical B.C. fishing vessel were experimentally and numerically investigated in a longitudinal seaway condition. The experimental model was self-propelled, radio-controlled and equipped with an on-board data acquisition system. Pitch, roll, yaw, surge, and heave responses to regular waves of predetermined frequencies and amplitudes generated along a 220-ft model basin were obtained. Different displacement conditions and GM configurations were tested. The numerical model for the dynamic analysis of the fishing vessel motions has been implemented using strip theory. A computer program was developed to study the nonlinear motions of the vessel. The velocity dependent coupling terms, responsible for a major part of the nonlinear behavior, were included. A time dependent component analysis of the roll damping has been performed. Regular linear and nonlinear waves were used. A parametric study of the fishing vessel stability has been carried out by considering its dynamic response in waves of varying characteristics. Unstable behaviour was found to be closely related to waves of length of similar magnitude to the ship length. The effects of wave amplitude and rudder usage were found to be of capital importance in the capsizing process. Experimental and numerical results showed good agreement.

Mestrado em Ciências do Mar e das Zonas Costeiras
The fishing sector has been suffering a strong setback, with reduction in fishing stocks and more recently with the reduction of the fishing fleet. One of the most important factors for this decrease, is related to the continuous difficulty to find fish with quality and quantity, allowing the sector work constantly all year long. However other factors are affecting negatively the fishing sector, in particular the huge maintenance costs of the ships and the high diary costs that are necessary for daily work of each vessel. One of the main costs associated with daily work, is the fuel consumption. As an example, one boat with 30 meters working around 17 hours every day, consumes 2500 liters of fuel/day. This value is very high taking into account the productivity of the sector. Supporting this premise was developed a project with the aim of reducing fuel consumption in fishing vessels. The project calls “ShipTrack” and aims the use of forecasts of ocean currents in the routes of the ships. The objective involves the use of ocean currents in favor, and avoiding ocean currents against, taking into account the course of the ship, in order to reduce fuel consumption and increase the ship speed. The methodology used underwent the creation of specific Software, in order to optimize routes, taking into account the forecasts of the ocean currents. These forecasts are performed using numerical modelling, methodology that become more and more important in all communities, because through the modeling, it can be analyzed, verified and predicted important phenomena to all the terrestrial ecosystem. The objective was the creation of Software, however its development was not completed, so it was necessary a new approach in order to verify the influence of the ocean currents in the navigation of the fishing ship "Cruz de Malta". In this new approach, and during the various ship routes it was gathering a constant information about the instant speed, instantaneous fuel consumption, the state of the ocean currents along the course of the ship, among other factors. After 4 sea travels and many routes analyzed, it was possible to verify the influence of the ocean currents in the Ship speed and in fuel consumption. For example, in many stages of the sea travels it was possible to verify an increase in speed in zones where the ocean currents are in favor to the ships movements. This incorporation of new data inside the fishing industry, was seen positively by his players, which encourages new developments in this industry.
O sector pesqueiro tem vindo a sofrer um forte revés, com a redução dos stocks de pesca e mais recentemente com a diminuição da frota de pesca. Um dos principais fatores mais importantes para esta diminuição está relacionado com a contínua dificuldade em encontrar peixe com qualidade e em quantidade, permitindo ao setor trabalhar constantemente durante todo o ano. No entanto, outros fatores estão a afetar negativamente o setor pesqueiro, nomeadamente, os grandes custos de manutenção das embarcações e os elevados custos diários que são necessários para o trabalho de cada embarcação. Um dos principais custos associados ao trabalho diário é o consumo de combustíveis. Como exemplo, uma embarcação com 30 metros de comprimento e que trabalha cerca de 17 horas diárias consome cerca de 2500 litros de combustível por dia, valor muito alto tendo em conta a produtividade do setor. Suportando esta premissa foi desenvolvido um projeto com o objetivo de reduzir o consumo de combustível por parte das embarcações pesqueiras. Este projeto chama-se “ShipTrack”, e tem como finalidade a utilização de previsões de correntes marítimas nas rotas efetuadas pelas embarcações. O objetivo envolve um aproveitamento das correntes a favor e evitar correntes contra, tendo em conta o rumo do barco, de forma a diminuir consumos de combustíveis e aumentar velocidades de navegação. A metodologia utilizada passou pela criação de um Software específico, de forma a otimizar rotas tendo em conta a previsão das correntes oceânicas. Estas previsões são realizadas com recurso à modelação, mecanismo que tem cada vez mais importância em todas as comunidades, pois através da modelação, podemos prever, antecipar e verificar fenómenos importantes para todo o ecossistema terrestre. O objetivo inicial consistia na criação de um Software para o sector pesqueiro, no entanto o seu desenvolvimento não ficou concluído durante a realização deste trabalho. Assim foi necessária uma nova abordagem de forma a verificar a influência das correntes oceânicas na embarcação de pesca “Cruz de Malta”. Nesta nova abordagem, e durante as várias rotas realizadas, foi recolhida constantemente informação sobre a velocidade instantânea, o consumo instantâneo e o estado das correntes oceânicas ao longo do percurso do barco, bem como outros fatores. Após 4 viagens oceânicas e muitas rotas analisadas, foi possível verificar a influência das correntes oceânicas na velocidade do barco e no consumo de combustível. Por exemplo, em muitas fases das várias rotas realizadas, foi possível verificar um aumento da velocidade em zonas onde as correntes oceânicas se encontravam a favor do movimento do barco. A incorporação de novos dados na indústria da pesca foi vista positivamente pelos seus intervenientes, o que encoraja a novos desenvolvimentos nesta indústria.

Abstract:
The goal of the project is to further the positivist discourse of design by ascertaining whether ethnographic analysis contributes to the design process. To this end, the project provides 1) a culturally appropriate conceptual fishing boat design and 2) an industrial design case study. This project identifies mechanistic and non-mechanistic design elements and presents the results of thematic analysis. This project develops a 40 GRT (gross register ton), Malaysian Class B fishing boat design based primarily upon ethnographic study of stakeholders, which includes fishermen, boat builders, designers and owners. The design concept is evaluated by fishermen regarding perceived performance as a fishing boat, aesthetics, safety, and comfort. The concept boat is compared with the visual stereotype of a traditional Malaysian fishing boat and a Western style, deck forward design. The conceptual design is evaluated with a creative product analysis matrix (CPAM) followed by a questionnaire based evaluation by fishermen. This project is intended for students and practitioners of industrial design interested in culturally appropriate design. It provides insights into design methodology and ethnographic methods for developing an understanding of indigenous design sensitivities of a client or end user. This study provides an example of product development that integrates the designer’s creativity with the stakeholders’ requirements and material culture. This project also demonstrates the technique of superimposing photographs via computer aided design (CAD) drawings to develop a visual stereotype. Moreover, this project demonstrates the benefit of employing visual models in charcoal and clay in ethnographic fieldwork.

Abstract:
Esta dissertação tem o objetivo de analisar as mudanças ocorridas nas condições de vida da população humana, na comunidade Canto do Mangue em Canguaretama (RN), e as possíveis relações com a introdução da carcinicultura a partir de 1980. Foram utilizadas técnicas de pesquisa qualitativa (análise documental, entrevistas e observações in loco) e quantitativa (análise de tendência central, dispersão e correlação). Constatou-se que as alterações ocorridas no espaço local estão associadas às pressões ocasionadas por fatores de ordens externa e interna, como a implantação e expansão dos projetos de carcinicultura, que levaram ao avanço da especulação imobiliária e intensificaram o desmatamento das áreas de manguezais ao longo do estuário do rio Curimataú/Cunhaú, contribuindo para o abandono da agricultura de subsistência nessa comunidade, além de estar levando também ao abandono da pesca artesanal, por conseguinte, a perda dos saberes da tradição aplicados na realização dessa atividade. Verificou-se, ainda, que as alterações no uso do território e dos recursos ameaçam a biodiversidade e têm contribuído para a redução dos estoques pesqueiros do município de Canguaretama e, conseqüentemente, do Canto do Mangue, sobretudo o estoque de caranguejo-uçá (Ucides cardatus). Os resultados obtidos permitiram concluir que a produção em larga escala numa economia de mercado, como se constitui a carcinicultura, desconsidera a busca de equilíbrio nas configurações territoriais. Assim, as perturbações ambientais decorrentes da carcinicultura têm conseqüências de dimensões sócio-culturais, afetando diretamente o modo de vida dos moradores do Canto do Mangue. As empresas de camarão têm absorvido parte dos pescadores que estão deixando a atividade pesqueira. No entanto, o baixo nível de escolaridade associado à idade são fatores que deixam muitos deles fora do quadro de funcionários dessas empresas. Portanto, há necessidade de se criar condições que possibilitem o desenvolvimento da carcinicultura sem colocar em risco a sustentabilidade da região.
The objective of this research was to analyze the changes occurred in the conditions of life in the human population, at community Canto do Mangue in Canguaretama (RN), and also their possible relationships with the introduction of the shrimp creation in captivity after 1980. Techniques of qualitative research were used (documentary analysis, interviews and observation in locus ) and quantitative (analysis of central trend, dispersion and correlation). It was evidenced that the occurred alterations in the local space are associated to the pressures caused by factors of external and internal order, such as implantation and expansion of the creation of shrimp in captivity projects. This led to the advance of the real estate speculation and intensified the deforestation of mangroves areas at the estuary of the river Curimataú/Cunhaú. It contributed to the abandon of the agriculture of subsistence in this community, as well as of handcraft fishing activity. Consequently, there was a loss of knowing traditional in the accomplishment of this activity. It was still verified that alterations in the use of territory and the resources threaten biodiversity and have contributed to the reduction of fishing supplies boats of the community of Canguaretama and consequently, the decrease of the quantity of shrimp (Ucides cardatus) at Canto do Mangue. The results allowed to conclude that the production in wide scale inside market economy, it disrespects the search of balance in the territorial configurations. Thus, the environmental disturbances caused by the shrimp creation of in captivity have social and cultural consequences, affecting directly the way of life of the Canto do Mangue inhabitants. The shrimp companies have employed part of the fishermen that are leaving the fishing activities, however the low level of scholarship and old age are factors that leave them out of team of employees of these companies. Therefore, conditions should be created to make possible to conciliate the shrimp creation in captivity and sustentability of the region.

Abstract:
AbstractRivers and peat swamps provide fishing grounds that can support the people living in Rantau Baru. Survey activities were conducted to describe the capture fisheries business carried out by fishers. The survey results show that 109 of 623 residents work as fishers, including women. Small-scale traditional fishing gear, such as traps, gillnets, mini long lines, set nets, pole and line, and cash nets are used, but traps are the dominant gear. Transportation to catch fish relies on boats, outboard motorboats, and fishing vessels. The outboard motorboat is widely used by fishers because of its small size and ability to navigate shallow and narrow waters. At least 44 species of fish from 10 families are caught and sold by fishers. Catches fluctuate according to the seasons, with increases during the flood season and decreases during the dry season. The fishing grounds also have potential for recreational fishing activities, as fishers earned US$37,242.67 from boat rental services for fishing-related tourism activities in 2019. This chapter provides an overview of the fishing activities and the economic value generated from fishing activities in the rivers and peat swamps of Rantau Baru.

Abstract:
AbstractTrawling has been recognised as a profoundly damaging practice with lasting negative consequences on seabed ecology and marine life since its first mention in a 1376 parliamentary petition. Mobile fishing gear (including any dredge, trawl, or similar device) is used to tow or push a net with a boat to catch fish. Bottom trawling, in particular, grew from a need to keep up with declining fish stocks and developed further with technological changes and increased demands, though it created ‘anger and resentment’ within the fishing communities (Bolster, 2012, p. 236). All three trawling revolutions—invention, mechanisation, and later deep-water expansion—have been met with controversy and pushback by the public and environmentalists alike (Roberts, 2008).

Abstract:
AbstractIn order to understand the mechanism of the surf-riding/broaching profoundly, the four- degree- of-freedom(4DOF) maneuvering equation (surge, sway, yaw and roll) is simplified to a one- degree-of-freedom (1DOF) equation, and the fourth-order Runge-Kutta method is used to integrate a 1DOF surge equation in the time domain to analyze the two motion states of the ship during the surging and surf-riding. The critical Froude number is calculated using the Melnikov method. Taking a fishing boat as an example, the ship’s surf-riding/broaching phenomenon is simulated under the condition of wavelength-to-ship-length ratio and wave steepness, 1 and 1/10 respectively, providing technical support for the formulation of the second generation intact stability criteria.

Abstract:
Investigation into the roll damping of Nova Scotia inshore fishing boats, known locally as Cape Island boats has been carried out. The roll damping coefficients are obtained for the computer simulation of Cape boat motion in large waves. Cape boats have low length to beam ratio, very shallow draft, and a deep skeg. Time history of the roll decay tests shows stiff and heavily-damped roll motions which only last for one-and-a-half to two cycles. The four models chosen in the test cover a wide range of Cape boat designs. It is found that the damping coefficients are both nonlinear and roll angle dependent. The data analysis procedure and results are presented in this paper.

Abstract:
In order to simulate the bottom trawl fishery in Ise Bay, a typical semi-enclosed bay in Japan, a fishery simulator has been developed that consists of a fish behavioral model and a fishing operations model. The fish behavioral models are developed for two major target species, conger eel and mantis shrimp, which consider the fish migration as well as the growth and the population change. The fish behavioral models are combined with a fishing operation model, which predicts the behavior of trawling boats based on economic conditions and resource distribution as well as the fish catch amount by each boat. The model is applied to evaluate the effects of fishery management, and it is investigated that how the control of fishing efforts or number of owned fishing boats affects the profit of the target fishery. The mesh size of the trawling net which maximizes the total catch is estimated considering both conger eel and mantis shrimp. At the target ports, reduction of boats number will increase the profit because the effect of fixed cost change exceeds the impact of fish catch decrease. However, the optimum reduction rate is different in each port and interactive effect should be also considered.

Abstract:
There is a lack of information about fisheries and fishing boat building traditions in Egypt during the Islamic era (starting18 AH /639 AD/CE), as most sources from this period only focus on commercial or military activities. Therefore, this research refers to the types of boats that were recorded by foreign travelers to Egypt during the period under study. This report highlights that the use of rafts continued in Egypt throughout the Islamic era, as illustrated by Captain Frederick Ludwig Norden the Younger during his travels on the Nile with the Danish Navy in 1737. He noted that the Egyptians used rafts for fishing and for crossing the Nile. In addition, papyrus boats were widely used for fishing and river crossings in the ancient pharaonic era, a tradition that continued into the Islamic period. Finally, wooden boats were also built for the purpose of fishing.

Abstract:
This study looks at fishing activity in the Philippines’ Exclusive Economic Zone in 2012, as well as how it responded to tropical cyclones. The study identifies the main fishing grounds and examines the impact of tropical cyclone speed on vessel position using satellite images and tropical cyclones data. Data suggest that tropical cyclones have a negative impact on fishing activity, with fewer active boats during and after the storm. The most affected locations include the Sibuyan Sea, Visayan Sea, and Panay Gulf. These tropical cyclones were estimated to reduce commercial fishing production by 7,800 tons per day, affecting more than 188,000 families in Western Visayas.
