Effects of protection on large‐bodied reef fishes in the western Indian Ocean
Conservation Biology, Volume 39, Issue 4, August 2025.Abstract Predatory and large‐bodied coral reef fishes have fundamental roles in the functioning and biodiversity of coral reef ecosystems, but their populations are declining, largely due to overexploitation in fisheries. These fishes include sharks, groupers, Humphead wrasse (Cheilinus undulatus), and Green Humphead parrotfish (Bolbometopon muricatum).

Environmental DNA preserved in marine sediment for detecting jellyfish blooms after a tsunami
Scientific Reports, 2021 Environmental DNA (eDNA) can be a powerful tool for detecting the distribution and abundance of target species. This study aimed to test the longevity of eDNA in marine sediment through a tank experiment and to use this information to reconstruct past ...

Morphological differences between cultivated and wild jack mackerel Trachurus japonicus.
NIPPON SUISAN GAKKAISHI, 1987 Morphological differences between the cultivated and the wild Japanese jack mackerel, Trachurus japonicus are examined as a part of obtaining knowledge on the degree of the intra-specific variation of T. japonicus and in order to find out what kind of morphological variations appear under the cultivated condition.

The Northern Anchovy reduction fishery for the 1978-79 through 1981-82 seasons [PDF]
, 1985 Nearly 49,000 metric tons (MT) of anchovies were taken during the 1978-79 season, followed by 32,390 MT in 1979-80, 60,678 MT in 1980-81 and 45,150 MT in 1981-82. A total of 14,076 fish was sampled during the four seasons for age, length and sex.

How Fragmented Is eDNA? A Case Study on Shark DNA in Tropical Reef Seawater
Environmental DNA, Volume 7, Issue 4, July–August 2025.This study quantified mitochondrial eDNA fragment lengths in offshore tropical seawater using qPCR assays targeting amplicons from 119 to 15,727 bp in tiger shark (Galeocerdo cuvier). Copy numbers steeply declined with increasing fragment size, with successful amplification up to 1518 bp and a calculated mean undamaged fragment size of 256 bp.

Southern California marine sport fishing from privately-owned boats: catch and effort for July-September 1981 [PDF]
, 1982 The catch landed and effort expended by private-boat sport fishermen were studied in southern California between July and September 1981, in order to determine the impact of one segment of the sport fishery on local marine resources.

Highly mobile pelagic species co‐occur with fine‐scale ocean fronts
Limnology and Oceanography, Volume 70, Issue 7, Page 1901-1912, July 2025.Abstract Coastal areas are an important source of food and a valuable tourism asset for communities, but also highly dynamic and heterogeneous environments. Understanding how marine species respond to the variability of their habitat is essential to sustainably manage coastal resources.
