    Beschreibung: This open access book explores fishing livelihoods in the context of the wider contexts in which they are embedded. Drawing on case studies from across the Asia-Pacific region, the book highlights how fishing livelihoods are shaped by globalisation, social relationships and governance. The book concludes by showing how better understanding these relationships can contribute to governance for healthier ecosystems and social wellbeing. This is an open access book. This is an open access book.

    Beschreibung: Caspian trout (Salmo trutta caspius) is one of valuable fishes of the Caspian sea for people living in the Northern coastal area of Iran. Since fish stock and natural resources protection is one the Iranian fisheries research objectives, the most activity on Caspian trout rehabilitation was focused on releasing thousands of smolts in the rivers discharge to Caspian Sea. Catch statistics of this species has declined over last decades thus this study on quality of provided brood stocks and producing fries with suitable quality can help rehabilitation and rearing of this valuable species. Several rivers were considered for providing brooders to keep genetic resources variety of sea stocks. In spawning season 25 (9 male, 16 female) and 30 (5 male, 25 female) brooders were collected from fishermen in Mazandaran rivers and Gyilan coasts provinces respectively. After propagation and larvae rearing, 11500 (10-15 g.) and 50000 (less than 10 g.) juveniles were released in Gyilan and Mazandaran rivers respectively.

    Beschreibung: An artificial Reef is a fabricated, underwater structure, typically built for promoting marine life in areas of generally featureless bottom. Creating artificial reefs began from 2000 in southern provinces in Iran. This study has surveyed about the Bushehr and Khozestan states. The objective is to determine the effectiveness of artificial reefs in attracting and enhancing the production different aquatics through increasing of fish assemblage and fishery. The performance of artificial reefs deployed off the coast of the Persian Gulf in 10 to 15m, was evaluated. The reefs comprised of seven artificial and one control (natural) statistical tests plan in three replicates. Three types of artificial reefs were used in this study. That two were designed reefs and one was not designed or used material. The experimental plan consisted (i) Reef ball (R), designed hemispherical shaped; (ii) Laneh Mahi (L), designed pyramid shaped; (iii) Used material (U); (iv) mixed (RL); (v) mixed (RU); (vi) mixed (LU); (vii) mixed (RLU); and (viii) control site (CS). Trap nets and under-water visual census surveys were adopted for seasonal sampling of fish aggregation. Results of statistical analysis using ANOVA and T-test of the mean Catch per Unit Effort (CPUE) showed significant difference (p〈0.05) in term of computing number of fish for aggregation of fishes. The study has concluded that reef deployments have influenced favorably the fish communities and fish harvests. Therefore, the artificial reefs, especially the mixed RLU, are appropriate tools for future fishing enhancement in the Persian Gulf of Iran.

    Beschreibung: Gillan , Mazandaran and Gorgan provinces have temperate climate, thus they have more potential for aquatic animal culture. There are thousands hectare of lands for Aquaculure and fisheries in adjacent to Caspian Sea in this provinces. these areas(North alborz) have provided a favorable back ground for aquatic animal breeding and stock enhancement of species in the sea. As a result, this investigation executed during two stages (phases). At first stage, the goal of this project included the feasibility study and demonstrating the existing situation of fish stock enhancement activities in North Alborz area and second phase is to survey on distribution, and production activities of stock enhancing hatcheries as well as their constructions,and production time table. Survey was started frome 2006 to 2008 by using qestionaries in 7 hatcheries from tree provinces.results revieled that there are more than 10 species was subjected to restocking .Total releasing was about 300 millions of fry and finger lings in to the Caspian sea.

    Beschreibung: Beach seine is fishing gears that occupy all depths of water from surface to bed by non-gillnet net. Increasing non-standard catches caused this survive was done to standardization of the beach seine mesh size. The research was started from winter of 2017 to spring of 2017, performing 73 hauling with four mesh sizes of 26, 28, 30 and 33 mm (knot to knot) in the bag area of ​​the beach seine in Miankaleh region of Golestan Province. According to the mesh size used in the bag section, the results showed that the highest amount of catches from different mesh size was done in size of 26 mm. Also, the maximum lengths were found for Liza aurata, Risso, 1810 in different mesh size in the 30-35 cm class length and for Alosa caspia, Linck, 1790 for 35-40 cm and for Rutilus kutum, Kamensky, 1901 at 30 to 35 cm. Also, in the mesh size of 26 mm, 50 percent of Lisa fish was caught at the length of 24.87 centimeters, in mesh size of 30 mm, 25.66 centimeters and mesh size of 32 mm, 26.65 centimeters. Also, the length of 50% of the permitted catch was obtained 25.5 centimeters by using 30 mm mesh size. According to the results, it was found that the Beach seines in the region did not caught selective and did catch much fish below the standard length.

    Beschreibung: The "fisheries and aquaculture industry innovation system" is one of the subsystems of Agricultural innovation system (AIS), also has many characteristics of that system .Since this section contains most of the components and AIS institutions, it can be examined as a part of the national innovation system. Due to the structure of the innovation system in the fishery system, a set of functions and institutions of this system are most important .It is therefore important that the system be analyzed and by reviewing the existing state institutions and functions of this system, the main problems and challenges identified. Understanding of the institutions and functions of fishery innovation system and analyze its problems and provide an improved model for fishery innovation system, is most activity in shaping major policy innovation in fishery sector. This step is very important to conduct innovative activities in the fishery sector. In this study, using a system perspective, the current status of the various factors affecting fishery development was assessed and the main drivers and challenges and solutions to improve the detection and analysis was provided. The results show that during the past eighty years, a number of research centers and educational institutions in the public sector have been developed .but this system, despite having considerable institutional capacity, is still in the middle stages of institutional development. In these years, the policy approach was linear, not system approach, so little attention has been to the development of science and technology intermediary institutions, coordinator organizations, venture capital funds, and the institutions of technology transfer ,particularly in the public sector.
