Southern California marine sport fishing from privately owned boats: catch and effort for April - June 1982 [PDF]

, 1983
The catch landed and effort expended by private-boat sport fishermen in southern California were studied between April and June 1982, in order to determine the impact of this segment of the sport fishery on local marine resources. Fishermen returning

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.

Occurrence of Anisakis and Hysterothylacium nematodes in Atlantic chub mackerels from Libyan coasts

Helminthologia, 2019
The occurrence of zoonotic parasitic nematodes in Atlantic chub mackerels (Scomber colias syn. Scomber japonicus) from Libyan waters was investigated, using epizootiological estimations and molecular specific characterization of larvae.

Optimal Strouhal number for swimming animals [PDF]

, 2011
To evaluate the swimming performances of aquatic animals, an important dimensionless quantity is the Strouhal number, St = fA/U, with f the tail-beat frequency, A the peak-to-peak tail amplitude, and U the swimming velocity.

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

Fisheries Oceanography, EarlyView.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

Advances in methods for determining fecundity: application of the new methods to some marine fishes [PDF]

, 2009
Estimation of individual egg production (realized fecundity) is a key step either to understand the stock and recruit relationship or to carry out fisheries-independent assessment of spawning stock biomass using egg production methods.

Enhancing fish community monitoring at a cabled observatory by combining environmental DNA and imaging analysis

Journal of Fish Biology, EarlyView.
Abstract Cabled multiparametric observatories are sustaining ecological monitoring by collecting long‐term real‐time biological and environmental data. Here, we investigated fish communities by sampling environmental DNA (eDNA) over 4 days near the multiparametric cabled video‐observatory OBSEA (Northwestern Mediterranean Sea).

Implications of fisheries during the spawning season for the sustainable management and recovery of depleted fish stocks: life history characteristics of several North Sea species [PDF]

, 2009
Fish traders and NGOs have put the idea forward that in order to not disturb the spawning process and hence improve the reproductive success of a fish population one should stop fishing during the spawning period.
