Catching Polygons

open access: yesCoRR, 2022
Consider an arrangement of $k$ lines intersecting the unit square. There is some minimum scaling factor so that any placement of a rectangle with aspect ratio $1 \times p$ with $p\geq 1$ must non-transversely intersect some portion of the arrangement or unit square. Assuming the lines of the arrangement are axis-aligned, we show the optimal arrangement

Illicit trade in marine fish catch and its effects on ecosystems and people worldwide

open access: yesScience Advances, 2020
Illicit trade in marine fish catch results in losses to society that can be measured in billions of dollars each year. Illegal, unreported, and unregulated fishing is widespread; it is therefore likely that illicit trade in marine fish catch is also ...

Catching up [PDF]

open access: yesClinical Anatomy, 1996
The medical school I (S.M.) attended did not require dissection of a cadaver to fulfill the requirements of the anatomy curriculum. I had "learned" human anatomy through lectures, text books, and an atlas, but did no dissection. Although it was difficult doing anatomy that way, I passed basic science exams with high marks and did well on the board ...

Increasing biological knowledge for better management of by-catch species: age, growth, and mortality of piper and red gurnards (Teleostei: Triglidae)

open access: yesScientia Marina, 2023
Gurnards are a valuable by-catch of mixed demersal fisheries and are commercially important in European waters, but they are often discarded, reported under “mixed gurnards” and with incomplete biological information by species.

Identification of ACE I-Inhibitory Peptides Released by the Hydrolysis of Tub Gurnard (Chelidonichthys lucerna) Skin Proteins and the Impact of Their In Silico Gastrointestinal Digestion

open access: yesMarine Drugs, 2023
Tub gurnard is a highly abundant fishery species caught as a discard in the Mediterranean Sea. This work proposes its valorisation through the release of potential antihypertensive peptides and glycosaminoglycans (GAGs) through the controlled hydrolysis ...

Conservation Concerns of Small-Scale Fisheries: By-Catch Impacts of a Shrimp and Finfish Fishery in a Sri Lankan Lagoon

open access: yesFrontiers in Marine Science, 2018
By-catch is considered a significant problem in large-scale fisheries yet in small-scale fisheries (SSF), employing >99% of the world's fishers, there is limited quantitative understanding of by-catch, and catches in general.

Selectivity of diamond and square mesh cod ends for horse mackerel (Trachurus trachurus), European hake (Merluccius merluccius) and axillary seabream (Pagellus acarne) in the shallow groundfish assemblage off the south-west coast of Portugal

open access: yesScientia Marina, 2003
The effects of an increase in cod end mesh size from 65 to 70 and 80 mm and a change of mesh configuration from 65 mm diamond to 65 mm square mesh on the size selectivity of horse mackerel (Trachurus trachurus), hake (Merluccius merluccius) and axillary ...
