Effects of cryptic mortality and the hidden costs of using length limits in fishery management

Lewis G. Coggins, +4 more
- 01 Sep 2007 - 
TL;DR: In this article, the authors constructed a computer model to evaluate how discard mortality could influence the conservation utility of minimum length regulations and found that for overexploited fisheries with moderate-to-high discard mortality rates, reductions in fishing mortality will be required to meet management goals.

A suite of extensions to a nonequilibrium surplus-production model

Michael H. Prager
TL;DR: This paper reviews the logistic production model, starting with the basic differential equation and continuing with a description of the model development without the equilibrium assumption, and describes several extensions, including "tuning" the model to a biomass index; partitioning fishing mortality by gear, time, or area; and making projections.

The structuring role of free-floating versus submerged plants in a subtropical shallow lake

Mariana Meerhoff, +3 more
- 01 Oct 2003 - 
TL;DR: The results suggest that bottom-up effects of free-floating plants are weak when cover is low or intermediate, and cascading effects on phytoplankton through free- floating plant impacts on piscivorous fish are unlikely to be strong.

Bio-flocs technology application in over-wintering of tilapia

Roselien Crab, +3 more
- 01 May 2009 - 
TL;DR: Findings can help to overcome over-wintering problems, particularly mass mortality of fish due to low temperatures in the ponds, as well as avoid water quality deterioration.

Importance and Justification of Long-Term Studies in Ecology

Jerry F. Franklin
TL;DR: There is increasing recognition that, because most important questions in ecology ultimately deal with predicting ecosystem responses, testing the correctness of ecological concepts and predictions by observing the future is essential.
