Imprinting of Hatchery-Reared Salmon to Targeted Spawning Locations

A New Embryonic Imprinting Paradigm for Hatchery Programs Straying by hatchery-reared salmon is a major concern for conservation and recovery of many salmon populations. Fisheries managers have attempted to minimize negative ecological and genetic interactions between hatchery and wild fish by using parr-smolt acclimation facilities to ensure successful olfactory imprinting and homing fidelity. However, the... Read More

Relating Scientific Names to Common Names for Important Fisheries Species of the Mexican Pacific

by Mauricio Ramírez-Rodríguez Publications that involve the identification of important fisheries species generally do not relate scientific names to common names in landing records. For this reason, and in order to contribute to improving the  quality of fisheries statistics and the works based on them, Mexico’s National Commission of Aquaculture and Fisheries (CONAPESCA) and the...

A Historical Record of Sawfish in the Southern Gulf of Mexico: Evidence of Diversity Loss Using Old Photos

by Manuel Mendoza-Carranza and Alejandro Espinoza-Tenorio (Fisheries magazine: February 2015) Despite the conspicuous character of sawfish (Pristis spp.) in shallow estuarine waters, current records in the southern Gulf of Mexico are so scarce that they have been declared locally extinct from many areas where they formerly occurred (Fernandez-Carvalho et al. 2013). In Mexican waters of... Read More

Conserving Pacific Lamprey through Collaborative Efforts

Pacific Lamprey (Entosphenus tridentatus) have been an important part of the ecological community and co-evolved with aquatic species of the western rivers of the United States. Scarce information on Pacific Lamprey has hindered conservation and management efforts. To assess and conserve Pacific Lamprey, we developed a conservation initiative composed of three parts: assessment, conservation agreement,... Read More

Sustaining Freshwater Recreational Fisheries in a Changing Environment

Learning to Manage and Managing to Learn: Sustaining Freshwater Recreational Fisheries in a Changing Environment ABSTRACT: Freshwaters are being transformed by multiple environmental drivers, creating uncertainty about future conditions. One way of coping with uncertainty is to manage for resilience to unanticipated events while facilitating learning through adaptive management. We outline the application of these... Read More

Guiding Principles for Development of Effective Commercial Fishery Monitoring Programs

Monitoring of fishing activities is an essential component of successful fisheries management that can provide verifiable fishery-dependent data on fishing activities and help assess performance and success of fisheries management plans. Fishery managers and stakeholders have often struggled in developing and implementing effective monitoring programs due to lack of information, funding, and peer-to-peer learning from... Read More

Climate Change Effects on Aquatic Ecosystems and the Challenge for Fishery Management: Pink Shrimp of the Southern Gulf of Mexico

Ecosystems that change through time impose new scientific challenges for fisheries management advice. We present a case study to illustrate our view on how to face such challenges. The Pink Shrimp fishery in the Southern Gulf of Mexico has collapsed. Annual yields were about 24,000 metric tons during the mid-1950s to early 1970s; currently, they are about 1,200... Read More
