PREDATION UPON LARVAE OF THE PACIFIC SARDINE SARDINOPS SAGAX BY CYCLOPOID COPEPODS [PDF]

open access: yesJournal of Crustacean Biology, 1995
ABSTRACT Analysis of the zooplanktonic community during a diurnal cycle of sampling at the entrance of Magdalena Bay, during the period of highest reproductive activity of the Pacific sardine Sardinops sagax, showed the presence of 80 zooplanktonic taxa of which only the copepods Corycaeus truckicus and C.

Growth rate of larval Sardinops sagax from ecosystems with different levels of productivity [PDF]

open access: yesMarine Biology, 2001
Otolith increment data were used to age larval Sardinops sagax from shelf waters between 118°E and 137°E off southern Australia. Maximum and mean growth rates up to an age of 30 days, estimated from a Laird–Gompertz model, were 0.62 and 0.48 mm day–1, respectively. The growth rate of larval S.

Feeding habits of sardine (Sardinops sagax) in relation to their spawning activities [PDF]

open access: yes, 2023
Feeding activity of sardine (Sardinops sagax) from St Helena Bay and Gans Bay in the Southern Benguela was studied between February and April 2011 and related to reproduction. Feeding intensity of 373 sardine was calculated and correlated with caudal length across different gonad maturity and fat stages.

Density-dependent changes in reproductive parameters and condition of southern Benguela sardineSardinops sagax [PDF]

open access: yesAfrican Journal of Marine Science, 2006
The sardine Sardinops sagax population in the southern Benguela has undergone substantial fluctuations in size over the past 50 years, collapsing from an apparently large population in the 1950s to low levels in the mid-1960s, remaining low for the next ...

Characterization of polymorphic microsatellites in the Pacific sardine Sardinops sagax sagax (Clupeidae)

Molecular Ecology Notes, 2004
AbstractWe isolated 11 microsatellites from the Pacific sardine Sardinops sagax sagax. The number of alleles and HE among 30 individuals from a single population ranged from four to 24 and from 0.606 to 0.959, respectively. Pacific sardines are a vital economic resource in the northeastern Pacific Ocean, but insufficiently polymorphic loci have limited

Physical effects of sound exposure from underwater explosions on Pacific sardines (Sardinops sagax).

Journal of the Acoustical Society of America, 2020
Explosions from activities such as construction, demolition, and military activities are increasingly encountered in the underwater soundscape. However, there are few scientifically rigorous data on the effects of underwater explosions on aquatic animals,

Polyhalogenated Compounds (Halogenated Natural Products and POPs) in Sardine (Sardinops sagax) from the South Atlantic and Indian Oceans.

Journal of Agricultural and Food Chemistry, 2020
PHalogenated natural products (HNPs) and persistent organic pollutants (POPs) were quantified in South African sardines (Sardinops sagax) from one site in the South Atlantic and one in the Indian Ocean.

The effects of freezing on the morphometrics of sardine Sardinops sagax (Jenyns, 1842)

Fisheries Research, 2010
Abstract The effects of freezing on the morphometrics of sardine Sardinops sagax were studied. Results were variable depending on the length of the freezing period, but all fish showed significant ...
