Summary: This study focuses on high seas fisheries and demonstrates how in situ target strengths can be measured using an acoustic optical system, proposing new TS-SL equations for orange roughy. Findings suggest that existing equations may not be suitable for larger fish, resulting in potential biomass estimation discrepancies. The use of AOS is practical and cost-effective for deep-water fisheries management.

Summary: Understanding population connectivity and genetic diversity is crucial for conservation, but it remains challenging for globally threatened marine megafauna. This study uses a comparative framework to investigate the genetic differentiation and diversity of manta rays, revealing higher connectivity and heterozygosity in oceanic manta rays. The findings also emphasize the potential impact of fisheries on population dynamics.

Summary: Genomic information can be used to establish sustainable management plans for commercially exploited marine fishes, such as the southern African hakes. The study found that the two hake species, M. capensis and M. paradoxus, have similar levels of genomic diversity but exhibit different population structures. The findings provide valuable insights for conservation and management efforts for these commercially important species.

Summary: This study focuses on two commercially important gadoid species, the common ling and the blue ling, which have overlapping geographical distribution but different depth habitats. Genotyping-by-sequencing analysis revealed genetic differentiation in both species, with two major groups identified for each species. Fine-scale genetic structure was found along the coast of Norway for the common ling, while the blue ling showed stronger signals of differentiation related to adaptation to different depth habitats and cold temperatures.

Summary: Deep-sea Chondrichthyes, including the kitefin shark Dalatias licha, are highly vulnerable to human impacts due to their late maturation, extreme longevity, low fecundity, and slow growth rates. However, assessing the impact of deep-sea fisheries on these species is challenging due to the lack of fishery data sets and species-specific life history information. This study presents data on the kitefin shark collected as bycatch from deep-water fisheries in the Ligurian Sea, highlighting the rarity, complex ecology, and threats this species faces, emphasizing the need for monitoring and conservation efforts.

Summary: Spatial stock assessment models are important for estimating stock status and sustainable exploitation. By distributing information on biological parameters between neighboring units, spatial modeling can be applied in data-limited situations. This approach was successfully applied to neighboring seamounts in the South Pacific to fit multiple localized depletion dynamics models.

Summary: This study evaluates the biogeographic patterns of deep-sea benthic taxa in the Southern Indian Ocean, aiming to understand conservation strategies for the Southern Indian Ocean Fisheries Agreement (SIOFA) management organization. The research reveals a significant lack of distributional data in the area, but identifies unique bioregions. It calls for biodiversity inventories in this region to inform conservation decisions.

Summary: This study demonstrates the application of genomic techniques in detecting hybrid populations of golden perch in the Murray-Darling Basin, southeast Australia, revealing admixture through a genome-wide dataset of 6,862 SNPs. The research suggests that stocking programs may introduce non-endemic ancestry, impacting genetic variation in the wild.

Summary: The black rhinoceros is a critically endangered species in Africa, with its population and distribution greatly reduced due to hunting, habitat disturbance, and poaching crisis. Genetic and genomic assessments were conducted on museum specimens collected between 1775 and 1981, revealing the historic population structure and evolutionary history. Results indicated that the black rhinoceros had six major historic populations with subpopulations, largely corresponding to geography, and population discontinuities were driven by geographical barriers. This comprehensive historic portrait also provided insights for conservation management strategies.

Summary: Although Ipnops specimens are common in the Clarion-Clipperton Fracture Zone (CCZ), a reliable species identification has not been possible due to the lack of captured specimens. However, a recent study utilizing morphological analysis and DNA barcoding successfully identified a specimen as Ipnops meadi and provided a better understanding of its morphological characteristics. Furthermore, the study suggests the presence of a previously undescribed Ipnops species in Australian waters.

Summary: The study characterized the population genetic diversity and structure of the spotted handfish, revealing three genetic groupings within the estuary and significant variance in allele frequencies among populations. Low genetic homogeneity and migration rates suggest separate conservation units within the estuary may be necessary for management and conservation strategies of this species and others in the family.
