Proteomic mechanisms underlying soybean meal‐induced enteritis resistance in selected rainbow trout

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 6, December 2025.
Abstract Soybean meal‐induced enteritis (SBMIE) remains a major barrier to reducing fishmeal use in salmonid aquaculture. This study evaluated physiological and molecular responses associated with SBMIE resistance in rainbow trout (Oncorhynchus mykiss) by comparing a commercial strain (Com) and a selectively bred strain (Sel) with over two decades of ...

Results of abundance surveys of juvenile Atlantic and gulf Menhaden, Brevoortia tyrannus and B. patronus [PDF]

open access: yes, 1989
The estuarine populations of juvenile Atlantic and gulf menhaden (Brevoortia tyrannus and B. patronus) were sampled during two-boat, surface-trawl, abundance surveys extensively conducted in the 1970s.

Influence of environmental conditions on the age, hatch dates, and growth of juvenile Atlantic menhaden in the Choptank River, MD [PDF]

open access: yes, 2016
Since 1993 Atlantic menhaden has experienced sustained low juvenile production (recruitment) in the Chesapeake Bay. Factors controlling growth, abundance, and mortality of larval and juvenile menhaden change throughout ontogeny such that larval growth ...

Diet and Trophic Ecology of Invasive Blue Catfish Ictalurus furcatus in an Eastern Shore Tributary of the Chesapeake Bay

open access: yesFishes
Blue Catfish Ictalurus furcatus were first introduced to Virginia tributaries of the Chesapeake Bay in the 1970s and have greatly expanded in population size and distribution, prompting ecological and economic concerns.

Bottom‐Up Interactions in State‐Space Age‐Structured Models Using Mass‐Balance Dynamics

open access: yesFish and Fisheries, Volume 26, Issue 6, Page 1048-1064, November 2025.
ABSTRACT Age‐structured models are used worldwide to regulate fisheries. These models typically ignore top‐down interactions (predation affecting natural mortality) and bottom‐up interactions (consumption affecting individual growth, reproduction, or survival), whereas multispecies catch‐at‐age models often incorporate top‐down but not bottom‐up ...

Endogenous nutrient mobilization during egg and larval development in two marine fishes - Atlantic menhaden and spot

open access: yes, 1995
Volume measurements of yolk and oil globule, and analyses of protein and free amino acids (FAAs) of developing eggs and larvae of Atlantic menhaden (Brevoorlia tyrannus) and spot (Leiostomus xanthurus) were carried out.

Spatial and Temporal Dynamics of Larval Atlantic Menhaden on the East Coast of the United States [PDF]

open access: yes, 2016
Atlantic Menhaden Brevoortia tyrannus is a commercially and ecologically important forage fish abundant on the Atlantic Coast of the United States. We conducted spatial and temporal analyses of larval Atlantic Menhaden using data collected from two large-

The Impact of Multiple Nursery Areas on the Population Structure of Atlantic Menhaden, \u3ci\u3eBrevooria tyrannus\u3c/i\u3e [PDF]

open access: yes, 2014
Understanding the population structure and patterns of connectivity in marine fishes is essential when making predictions about a species\u27 resiliency and persistence in an increasingly changing environment. The Atlantic Menhaden Brevoortia tyrannus is

Northern Extension of Known Range of Atlantic Menhaden (Brevoortia tyrannus)

open access: yes, 1974
Ten specimens of Atlantic menhaden (Brevoortia tyrannus) were taken in salmon trapnets near Dalhousie, New Brunswick, from June 18 to July 19 in 1973. The northern limit of range of the species was previously considered to be western Nova Scotia.
