The Fish Behind Fish Feed: Rethinking Transparency Using DNA Tools

Fish and Fisheries, EarlyView.
ABSTRACT Aquaculture is now the fastest growing food sector and may be a promising solution to increasing seafood demands. Yet, carnivorous aquaculture species such as salmon and seabass continue to rely on fishmeal and fish oil (FMFO), which are derived largely from pelagic fish that are sometimes key to the food security of some coastal nations.

The status of the Pacific sardine resource and its management [PDF]

, 1973
The Pacific sardine fishery has declined from a catch of almost 8 hundred-thousand tons in the nineteen thirties to relative insignificance at present. This decline was primarily due to the decline of the northern subpopulation.

Power-law scaling in dimension-to-biomass relationship of fish schools

, 2005
Motivated by the finding that there is some biological universality in the relationship between school geometry and school biomass of various pelagic fishes in various conditions, I here establish a scaling law for school dimensions: the school diameter ...

Revisiting Maturity Data: Using Oocyte Diameter and Gonadosomatic Index to Retroactively Apply a New Maturity Scale to Greenland Halibut (Reinhardtius hippoglossoides)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Greenland halibut (Reinhardtius hippoglossoides) is a deep‐water flatfish which lives at temperatures of 1°C–4°C and produces large eggs (> 3 mm). The combination of low temperatures and large eggs has resulted in an unusual ovary development cycle, with vitellogenesis taking more than 1 year.

Predicting the age of sardine juveniles (Sardina pilchardus) from otolith and fish morphometric characteristics

Scientia Marina, 2015
An age prediction model based on individual morphometric characteristics (total length; weight) and otolith morphometric characteristics (diameter; weight) was investigated for juvenile sardine, Sardina pilchardus (Walbaum, 1792).

Status of the Jack Mackerel resource and its management [PDF]

, 1973
The jack mackerel, Trachurus symmetricus, resource off the west coast of North America is known to be large and widely distributed. The spawning biomass is estimated to be 2.1 to 4.8 million tons based upon abundance of jack mackerel eggs collected at ...

Vertical Habitat Use by Japanese Jack Mackerel Trachurus japonicus Inferred From a Biologging Study in Tokyo Bay

Fisheries Oceanography, EarlyView.
ABSTRACT The movement ecology of Trachurus japonicus in the adult stage remains poorly understood because observing their underwater behavior over long periods is challenging. This study aimed to examine vertical habitat use by T. japonicus using electronic tags. Ninety fish were tagged and released in November 2022 in Tokyo Bay, Japan.

Morphological characteristics of smoothbelly sardinella, Amblygaster leiogaster (Val.) in the Bay of Bengal

Fisheries & Aquatic Life
Species identification, classification, and the genetic studies of fishes rely principally on meristic counts and morphometric characteristics. The current study was designed to provide the first comprehensive, instructive description of the meristic ...

Culture viability of Sardina pilchardus (Fish, Teleost): Preliminary results of growth in captivity up to 18 months

Scientia Marina, 2014
Larvae of Sardina pilchardus were obtained in captivity from fertilized eggs captured in the wild and grown in a 10000-L tank. Isochrysis galbana, Artemia franciscana nauplii and live zooplankton were used as prey during the first two weeks; afterwards ...
