Status of the spawning biomass of the Pacific sardine, 1978-79 [PDF]
State law requires that the population of Pacific sardines, Sardinops sagax caeruleus, must reach a minimum spawning biomass of 20,O0O short tons before initiation of a fishery.

Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...

Thinking of Fish Population Discrimination: Population Average Phenotype vs. Population Phenotypes
The genetic polymorphism and phenotypic variation are key in ecology and evolution. The morphological variability of the contour of fish otoliths has been extensively used for the delimitation of stocks.

Historical Records of Tumours in New Zealand Marine Fishes
Tumours were first described in New Zealand marine fishes in 1982 but those early records have been difficult to access and subsequently few tumours have been collected and little has been published. This review updates records of identified tumours from teleosts in the New Zealand marine environment and may encourage more work to identify background ...

Status of the spawning biomass of the Pacific sardine, 1974-75 [PDF]
In order to initiate a fishery for the Pacific sardine, Sardinops sajax caeruleus, it is required that the spawning biomass be determined to have reached a minimum of 20,000 short tons.

ABSTRACT Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and ...

Modelling Fish Growth with Imperfect Data: The Case of Trachurus picturatus
Growth modelling is essential to inform fisheries management but is often hampered by sampling biases and imperfect data. Additional methods such as interpolating data through back-calculation may be used to account for sampling bias but are often ...

Food habits and dietary variability of pelagic nekton off Oregon and Washington, 1979-1984 [PDF]
The food habits of 20 species of pelagic nekton were investigated from collections made with small-mesh purse seines from 1979-84 off Washington and Oregon. Four species (spiny dogfish, Squalus acanthias; soupfin shark, Galeorhinus zyopterus; blue shark,

Thermal stabilities of inosine monophosphate-degrading enzymes in several fish muscles
The compositions and inosinic acid contents of ATP-related compounds in various processed fish meat products were examined in this study. Moreover, the relationships between these variables and the heating processes used on the products were investigated.
