TLDR
In this article, the effect of mesh size and towing speed on the multispecies catch rates obtained in different demersal surveys carried out in the Colombian Caribbean Sea between 1988 and 2001, using two generalized linear models: one covering the entire study area and another restricted to one ecoregion.About:

A review of bycatch reduction in demersal fish trawls
TL;DR: It is concluded that rigorous empirical assessments, initially focusing on the posterior trawl, but eventually encompassing anterior changes, are as important as the simplicity and reliability of modifications.
Impact of operational parameters on drag of trawl nets
TL;DR: In this article, the impact of operational parameters on trawl drag was assessed by multiple regression analysis where operational parameters such as depth of operation, warp length and towing speed were taken as independent variables and drag was taken as dependant variable.

The Effectiveness of the Jones/Davis Type By-Catch Reduction Device (BRD) to Reduce Unintended Catch of Trawl Fisheries
TL;DR: In this article, the authors examined the performance of Jones-Davis type BRD to reduce by-catch and its impact to prawn catch in Cleveland Bay and found that trawl equipped by BRD significantly reduce bycatch by 22.2% (Z = -4.6406, p-value = 0.0001).

Generalisation of Mood's Test to Factorial Designs to Detect Heterogeneity of Variances
Filiz Karaman,Erhan Çene +1 more
TL;DR: In this article, the power and robustness of these tests are examined in detail by means of a simulation study with 10,000 replications, based on the simulation results, the generalised Mood's and Klotz's tests can especially be recommended in settings in which the parent distribution is symmetric.

Trawler Engine Size Had No Effect on Baltic Herring Size/Age Structure: An Experimental Study in the Gulf of Riga, Baltic Sea
TL;DR: In this paper , the authors compared vessels with different engine powers using the same gears currently allowed in the gulf, to identify whether vessel power had any relation to catch structure, which were more dependent on season and depth of water.

An introduction to generalized linear models
TL;DR: In this paper, the authors propose a method of maximum likelihood estimation method of least squares estimation for generalized linear models for simple linear regression with Poisson responses GLIM, which is based on the MINITAB program.
