Reproductive schedules in southern bluefin tuna: are current assumptions appropriate? [PDF]

PLoS ONE, 2012
Southern bluefin tuna (SBT) appear to comprise a single stock that is assumed to be both mixed across its distribution and having reproductive adults that are obligate, annual spawners.

Support for the Slope Sea as a major spawning ground for Atlantic bluefin tuna: evidence from larval abundance, growth rates, and particle-tracking simulations

, 2021
Atlantic bluefin tuna (Thunnus thynnus) are commercially and ecologically valuable, but management is complicated by their highly-migratory lifestyle.

Route assessment of state of the spawning stock in the lower ritral of the Utesny creek (Paramushir Island, northern Kuril Islands, Sakhalin Region)

Известия ТИНРО, 2023
The route survey in the lower part of the Utesny creek (Paramushir Island) was conducted to explore the state of spawning grounds for pink salmon Oncorhynchus gorbuscha and to examine their filling by spawners.

Relationships among tissues, biofluids, and otolith selenium concentrations in wild female burbot (Lota lota)

Integrated Environmental Assessment and Management, EarlyView., 2023
Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

DEVELOPMENT OF FISH SPAWNING GROUND BY THE ARTIFICIAL SPAWNING MATERIAL

PROCEEDINGS OF CIVIL ENGINEERING IN THE OCEAN, 2001
The artificial spawning material in which Japanese sandfish lays eggs was developed. The 1st purpose is development of the mitigation technology which complements a spawning function until natural seaweed is reproduced. The breakwater to which Japanese sandfish is laying eggs in the present at Tomakomai Higashi port will be moved in the future. The 2nd

Spawning behaviour and post-spawning migration patterns of atlantic bluefin tuna (Thunnus thynnus) ascertained from satellite archival tags. [PDF]

PLoS ONE, 2013
Spawning behaviour of Atlantic bluefin tuna (Thunnus thynnus) was investigated using electronic satellite tags deployed in the western Mediterranean spawning ground, around the Balearic Islands (years 2009-2011).

A STUDY ON COASTAL STRUCTURES AS FISH SPAWNING GROUNDS LIGHT AND FLOWS AROUND SPAWNING GROUNDS OF SANDFISH

PROCEEDINGS OF CIVIL ENGINEERING IN THE OCEAN, 2001
In recent years, spawning of sandfish was observed in gulfweeds adhering to a breakwater in a sandy beach area of the Tomakomai East Port. This suggested that the breakwater served as a reef for sandfish to spawn on.This study focused on light and flows around a spawning ground of sandfish, for the purpose of adding a function as fish spawning grounds ...

Distribution, Feeding Habits, and Growth of Chub Mackerel, Scomber japonicus, Larvae During a High-Stock Period in the Northern Satsunan Area, Southern Japan

Frontiers in Marine Science, 2021
To evaluate the importance of the northern Satsunan area in southern Japan as a spawning and nursery ground for chub mackerel (Scomber japonicus), we investigated the early life history characteristics (e.g., larval distribution, feeding habits, and ...

Molecular and Morphological Identification and Seasonal Distribution of Eggs of Four Decapterus Fish Species in the Northern South China Sea: A Key to Conservation of Spawning Ground

Frontiers in Marine Science, 2020
Although species of Decapterus form important pelagic fisheries in the northern South China Sea, information on their spawning grounds is limited because identification of fish eggs based on their morphology is difficult.
