Abstract:

Poverty is the main factor triggering the high level of exploitation of fisheries resources. Prosperity of fishermen becomes primary key in fisheries development. Fisherman income level is primary factor in improving fishermen prosperity. The existence of a famine season is primary fishermen problem in fulfill the main needs. Because of it, this research is done with the purpose to see the fishermen income level in fish season, famine season and the average income of fishermen to determine the level of welfare of fishermen based on the type of boat used. The method is using fisheries business

Abstract:

Species that occur in low abundances and that are morphologically similar to the target fish are often undetectable in fisheries hauls; however, they add to the catch statistics of the target species. Using mitochondrial DNA and phylogenetic approaches we identified 6 individuals of the species Xenobrama microlepis in a haul targeting the southern Ray’s bream (Brama australis) taken by artisanal fishermen close to Chilean coast. The presence of X. microlepis increases the regional marine biodiversity of fishes in Chilean waters, and fisheries managers should pay attention to the hidden biodive

Abstract:

The fisheries sector has an important role in supporting the food security chain, where the world's protein needs can be met by fisheries resources, both from capture fisheries and aquaculture. There are several fisheries sectors including fishing companies, capture fisheries production, number of ships, types and size of cultivated land. Therefore a statistical analysis is needed to increase the potential of fisheries in Indonesia. Data on the fisheries sector used in this study from the Indonesian Central Statistics Agency in 2018, which included the 2016 fisheries sector with 34 observation

Abstract:

The reproductive biology of the black grouper Mycteroperca bonaci, caught by artisanal fishermen using hook and line or compressor - assisted spear fishing, from the Northeastern shelf and oceanic banks of Brazil, was studied between August 1996 and April 1998. The sexual pattern, gonadal development, the spawning mode and seasonality were investigated. The gonadal stages indicated that this species is a protogynous hermaphrodite and that transition from female to male occurs through simultaneous re-absorption of ovarian tissue and proliferation of testicular tissue in the gonads. The specie i

Abstract:

Frame and Catch Assessments of surveys of the fisheries of the Egbe reservoir were conducted to provide data needed for its management and development. Descriptive statistics was used to analyze the data. A total of 2748 fish species were assessed. 57 fishermen were recorded. Sixty wooden canoes were counted and recorded. Fishing gears recorded included (380) gill nets, (19) cast nets, (77) long lines, (1008) Malian fish traps, (3879) wire fish traps, and (13) spares. About 7 fish species from 5 families were identified. Cichlidae was the most relatively abundant family, contributing 75.9% to

Abstract:

We consider hierarchical regression models for circular data using the projected normal distribution, applied in the development of weights for the Access Point Angler Intercept Survey, a recreational angling survey conducted by the US National Marine Fisheries Service. Weighted estimates of recreational fish catch are used in stock assessments and fisheries regulation. The construction of the survey weights requires the distribution of daily departure times of anglers from fishing sites, within spatio-temporal domains subdivided by the mode of fishing. Because many of these domains have small

The development of the fisheries sector in Indonesia should get more attention, especially in efforts to increase fishing businesses, limited financial access is still a problem that must be faced by the fisheries sector. Thus, Islamic banking can play a significant role in providing financing for the development of national fisheries. This study analyzes the factors that influence fisheries financing in Islamic banking in Indonesia and how efforts to increase fisheries sector financing. The processed data source is the monthly statistics of the Islamic banking industry from October 2014 to Ma

Purpose: This study examined the challenges of artisanal fisheries in Zanzibar. The artisanal fishery is among the key segments of the emerging Zanzibar blue economy. Therefore, it is more than significant to examine the challenges of artisanal fisheries for spearheading the blue economy transformation in the country. Design/Methodology/Approach: The study was conducted in five villages in Zanzibar with a sample of 333.

Abstract The lack of reliable fisheries statistics hampers full assessment of the status of marine resources. Central to this problem are data-poor fisheries such as the Albanian seas and in particular the SSF sector. The present study aims to portray the small-scale fishery of south Albanian waters based on daily onboard monitoring of fisheries species catches during a two-year period (2016-2018). Results revealed a total of 6 and 11 fishing métiers for the nets and longlines, respectively. The most important target species for nets in terms of catches were Merluccius merluccius, Mullus surmu

Abstract:

Catch quota would be less effective to control fishing activities if fish production is not monitored properly. Limited support and participation of business players in fish monitoring program are contributing factors to the unreliability of fisheries statistics in many places, including Indonesia. To address this challenge, Indonesia fisheries managers may consider experiences of some fisheries management bodies with advanced monitoring system. This study analyzed the process of establishment of a monitoring system developed by Commission for the Conservation of Southern Bluefin Tuna (CCSBT)
