Ichthyocenosis of the upper epipelagic layer in the Pacific waters of Russia during japanese sar-dine «renaissance» in the beginning of the 21^st century

Известия ТИНРО
Dynamics of integral parameters for the species structure in ichthyocenosis of the upper epipelagic layer in the Pacific waters off the Kuril Islands in 2019–2023 is discussed in compare with previously published data since 2004 in context of a new bloom

The Niches of the Far Eastern Sardine and Japanese Anchovy

Asian Fisheries Science, 1992
The mean spawning seasons and locations and food items in stomachs of the Far Eastern sardine Sardinops melanosticta (Tamminck and Schlegel) and Japanese an­chovy Engraulis japonica (Houttuyn), which were considered as three dimensions of time, habitat and resource of the niches, were examined and compared with those of the chub mackerel Scomber ...

In‐vitro puncture experiment using alligator teeth tracks the formation of dental microwear and its association with hardness of the diet

The Anatomical Record, EarlyView.
Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

DataSheet_1_Investigation of inter-annual variation in the feeding habits of Japanese sardine (Sardinops melanostictus) and mackerels (Scomber spp.) in the Western North Pacific based on bulk and amino acid stable isotopes.pdf

, 2023
Inter-annual variation in the feeding habits and food sources of Japanese sardine and mackerel at age-0 and age-1+ caught in the Kuroshio-Oyashio transition zone of the Western North Pacific were investigated based on analyses of bulk stable isotopes ...

Macronutrient and micronutrient profiles of meat types: insights into human health and diet

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Despite considerable advances in global health and nutrition, emerging challenges such as population growth, climate change, and limited natural resources continue to threaten food security. Meat remains an essential component of the human diet, supplying high‐quality proteins, essential amino acids, lipids, vitamins, and minerals necessary ...

Genome Expansion of ZPB1(a) and ZPC1(a) in Basal Species or Liver Expression of ZPB1a and ZPC1aa in Advanced Species, Two Different Strategies to Ensure Sufficient ZP Synthesis in Teleosts

Integrative Zoology, EarlyView.
We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...

Regimes and stock-recruitment relationships in Japanese sardine (Sardinops melanostictus), 1951-1995

, 1998
We used reproductive success, rather than abundance or catch, to identify regimes because reproductive success responds faster to environmental changes.

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

Fisheries Oceanography, EarlyView.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

Profit and equity trade-offs in the management of small pelagic fisheries: the case of the Japanese sardine fishery [PDF]

, 2023
The management of small pelagic fisheries is difficult due to environmental regime changes that generate multi-decadal cyclic fluctuations in stock abundance. Lagged management responses to environmental factors can amplify the effects of fishing and may

Stable Isotope–Enabled Particle Drift Models Predict Where High‐Resolution Isotope Analyses Can Discriminate Among Larval Trajectories in Atlantic Mackerel

Fisheries Oceanography, EarlyView.
ABSTRACT Marine fish commonly move across distinct habitats throughout their lifetimes, particularly during larval stages, when they are particularly difficult to track. Such transitions are necessary as environmental demands and predation pressures change dramatically with increases in body size.
