Life history aspects of 19 rockfish species (Scorpaenidae: Sebastes) from the Southern California Bight [PDF]
The authors investigated various life history aspects of 19 rockfish species (Sebastes chlorostictus, S. constellatus, S. dalli, S. elongatus, S. ensifer, S. entomelas, S. flavidus, S. goodei, S. hopkinsi, S. levis, S. melanostomus, S.

Contrasting life‐history strategies of three sympatric icefish species in the northern Scotia Sea
Abstract Comprehending a species' life‐history strategies is crucial to inform effective conservation efforts. Commercial fishing impacts icefish (family: Channichthyidae) in the Scotia Sea, but detailed information on species‐specific life histories remains largely unknown.

Preliminary observations on the use of a frame trawl in hydroacoustic surveys [PDF]
Thirteen hauls were made during the hydroacoustic survey of the Ugandan waters of Lake Victoria from 7-19 February 1999. Ten of the hauls were made above the oxycline which was clearly visible as a strong echo on the echogram at between 25 and 35 m depth

Abstract The Deepwater Horizon (DWH) oil spill in the NE Gulf of Mexico in 2010 was the largest accidental spill globally. During and after the spill, oil was incorporated into marine snow (marine‐oil‐snow or MOS) and sedimented to the seafloor, accounting for ∼21% of the oil released.

In this paper, we proposed a mathematical model of a mid-water trawl system. The model consisted of towing warps, otter boards, a trawl net, and other rigging components. The warp and the net were modeled with the lumped mass method.

Ecology of Juvenile Walleye Pollock, Theragra chalcogramma: Papers from the workshop "The Importance of Prerecruit Walleye Pollock to the Bering Sea and North Pacific Ecosystems" Seattle, Washington, 28-30 October 1993 [PDF]
The Alaska Fisheries Science Center (AFSC), National Marine Fisheries Service (NMFS), hosted an international workshop, 'The Importance of Prerecruit Walleye Pollock to the Bering Sea and North Pacific Ecosystems," from 28 to 30 October 1993.

ABSTRACT Quantifying where marine organisms are born and subsequently disperse to is essential for fisheries management. Here, we conducted Lagrangian particle tracking of viviparous rockfish (Sebastes spp.) collected in the Southern California Bight over the course of 16 years.

Abstract The biological carbon pump sequesters carbon through passive fluxes of biologically derived carbon, and by active vertical movement of marine organisms. Trophic coupling between pelagic and benthic communities increases the efficiency of the biological carbon pump as less carbon is lost to remineralization.

Pacific Herring, Clupea pallasi, spawning population assessment for San Francisco Bay, 1992-93 [PDF]
We conducted hydroacoustic surveys, spawn surveys, and sampled schools and fishery landings from 8 November 1992 through 18 March 1993 to assess the status of San Francisco Bay's Pacific herring spawning population.

Driving anchovy larvae by large mesh wings of pair midwater trawl.
Wing meshes of commercial pair midwater trawls for catching anchovy larvae are as large as 360cm at the distal part and 15cm at the proximal part. Echo surveys were made using a 200kHz fish finder to examine if the larvae were driven into the net mouth by the wings of the extremely large meshes or escaped through the meshes.
