Modeling fish production for Southern California's petroleum platforms
California's oil platforms are nearing the end of their productive lives, and therefore will be decommissioned in the near future. These structures have been shown to be important habitat for both settlement and growth for reef fishes. Important information on the biological effects (i.e. loss of biomass and production) of different decommissioning options has not yet been explored in detail. ...

Feeding habits of the juvenile striped weakfish, Cynoscion guatucupa Cuvier 1830, in Bahía Blanca estuary (Argentina): seasonal and ontogenetic changes
The aim of this study was to analyze the feeding habits of the juvenile striped weakfish, Cynoscion guatucupa Cuvier, from Bahía Blanca estuary, Argentina. C. guatucupa is one of the most important regional fishing resources although in the last 10 years landings have greatly decreased. The year class strength of fish as well as stock size and yield are determined during the early life stages. ...

Probiotics vs. Enzymes: Understanding Your Aquaculture Products
We believe the future of aquaculture nutrition, disease management, and environmental treatment is biological. At QB Labs, we’re constantly looking at the effects of various microorganisms to replace antibiotics, augment natural fish/shrimp biological processes, and improve environmental impacts of commercial aquaculture. While educating customers on our products, we’re often asked ...

Chronic PFOS exposures induce life stage–specific behavioral deficits in adult zebrafish and produce malformation and behavioral deficits in F1 offspring
Perfluorooctane sulfonic acid (PFOS) is an organic contaminant that is ubiquitous in the environment. Few studies have assessed the behavioral effects of chronic PFOS exposure in aquatic organisms. The present study defined the behavioral effects of varying life span chronic exposures to PFOS in zebrafish. Specifically, zebrafish were exposed to control or 0.5 µM PFOS during 1 to 20, 21 to 120, ...

Predicting the effects of copper on local population decline of two marine organisms, cobia fish and whiteleg shrimp, based on avoidance response
Fry of the marine fish Rachycentron canadum (cobia) and larvae of the estuarine shrimp Litopenaeus vannamei (whiteleg shrimp) were exposed to a copper gradient which ranged from 0.20 to 1.80 mg Cu/L for the experiments with cobia and from 0.10 to 1.0 mg Cu/L for the experiments with whiteleg shrimp. The experiments focused on the avoidance response to predict the population decline. Avoidance ...

The Role of Mangroves in Fisheries Enhancement
In 2011 humans caught and consumed 78.9 million tonnes of fish, crustaceans, molluscs and other species groups from the world’s oceans, accounting for 16.6% of the world’s animal protein intake (FAO 2012). This is projected to increase further, to over 93 million tonnes by 2030 (World Bank 2013). Global demand for fish products has increased dramatically over recent decades. Fishing ...
