Efficiency and sustainability implications of artisanal fisheries activities: evidence from a developing country
Fisheries activities have an integral role to play in the livelihoods and economies of the Pacific island countries. However, the 'race to fish' behaviour assisted by the nature of property rights could lead to unsustainable resource extraction practices. In this paper, primary data on Fiji's artisanal fishermen and their fishing operation is used to examine their technical efficiency. Results ...

Challenges and opportunities for fisheries managers in developing countries: a case for economic eclecticism
Fisheries managers and advisors in developing countries face challenges that may be difficult to overcome, because they use doctrines, principles and models of management and economics that do not adequately explain the problems that need to be solved. This may perpetuate non-sustainable policies, because broader issues important to fisheries sustainability are not accounted for more eclectic ...

CYP1A expression in liver and gills of roach (Rutilus rutilus) after waterborne exposure to two phenanthrene derivatives, 1‐methylphenanthrene and 4‐methylphenanthrene
Phenanthrenes (Phs) substituted with alkyl groups are a class of compound present in the environment, and they appear to be toxic to developing fish. The present study aimed to investigate the effect of waterborne exposure to two monomethyl derivatives of phenanthrene, 1‐methylphenanthrene (1M‐Ph) and 4‐methylphenanthrene (4M‐Ph), on cytochrome P450 1A (CYP1A) gene expression in fish gills and ...

Inauguration of the pilot production plant in Spain
We have recently inaugurated our pilot production plant in Spain (San Pedro de Pinatar, Murcia). This plant is located in IMIDA – Instituto Murciano de Investigación y Desarrollo Agrario y Alimentario and was constructed to support the Algafeed Project, which has the aim to develop new fish feed based on marine microalgae. Preliminary results on the feed formulation are already quite ...

Nechako White Sturgeon Conservation Centre - Case Study
The Freshwater Fisheries Society of BC developed the Nechako White Sturgeon Conservation Centre to try to prevent extinction of this endangered species. Wild caught brood fish are held in the facility until spawning is complete. Controlled family groupings of young sturgeon are hatched in McDonald jars and reared for one year, first in 0.5 m3 and 1.5m3 combi tanks, then 8 m3 tanks before release. ...

Toxic concentrations in fish early life stages peak at a critical moment
During the development of an embryo into a juvenile, the physiology and behavior of a fish change greatly, affecting exposure to and uptake of environmental pollutants. Based on experimental data with sole (Solea solea), an existing bioaccumulation model was adapted and validated to calculate the development of concentrations of persistent organic pollutants in the tissue of developing fish. ...

Modelling the impacts of reservoir operations on the downstream riparian vegetation and fish habitats in the Lijiang River
River flow regulations have great impact on the downstream aquatic ecosystem. It is important to investigate the response of target species to the changes in hydrological regimes so that we can explore possible remediation measures. Ecohydraulics models that integrate hydrodynamics processes and ecological processes have been shown to be efficient in achieving these objectives. This study ...

An evaluation of fish early life stage tests for predicting reproductive and longer term toxicity from plant protection product active substances
The chronic toxicity of chemicals to fish is routinely assessed by using fish early life stage (ELS) test results. Fish full lifecycle (FLC) tests are generally only required when toxicity, bioaccumulation, and persistence triggers are met, or when there is a suspicion of potential endocrine disrupting properties. This regulatory approach is based on a relationship between the results of fish ...

Qualitative algal analysis from the fish-gut: Tested in the rice fish cropping system
Abstract: Algae constitute a major proportion of fish food in rice-fish culture system. Study of algal preferences and their availability in the natural environment might be important for developing natural fish feed. Preparation of formulated feeds using under-exploited materials such as algae not only reduces production costs, but also increases procurement accessibility of locally available ...

Modern strains put Lake Victoria in critical condition
Pollution and overfishing in Lake Victoria have become so severe that scientists believe they threaten the health and livelihoods of millions of East Africans. And researchers in the three countries bordering the world’s largest tropical lake — Kenya, Tanzania and Uganda — largely blame governments and national agencies for failing to control the effluent and other waste ...
