Revisiting Maturity Data: Using Oocyte Diameter and Gonadosomatic Index to Retroactively Apply a New Maturity Scale to Greenland Halibut (Reinhardtius hippoglossoides)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Greenland halibut (Reinhardtius hippoglossoides) is a deep‐water flatfish which lives at temperatures of 1°C–4°C and produces large eggs (> 3 mm). The combination of low temperatures and large eggs has resulted in an unusual ovary development cycle, with vitellogenesis taking more than 1 year.

Age and growth of swordfish (Xiphias gladius) caught by the Hawaii-based pelagic longline fishery [PDF]

, 2007
We verified the age and growth of swordfish (Xiphias gla-dius) by comparing ages determined from annuli in fin ray sections with daily growth increments in otoliths.

Post‐Release Survival of the Pelagic Stingray (Pteroplatytrygon violacea, Bonaparte, 1832) in French Longline Fisheries in the Northwestern Mediterranean Sea

Fisheries Management and Ecology, EarlyView.
ABSTRACT Bycatch remains a critical challenge in global fisheries, even when using selective gears such as longlines. In the French longline fishery targeting Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of Lion, the common pelagic stingray (Pteroplatytrygon violacea) is the primary bycatch species.

Consumption of Post-Larval Swordfish (Xiphias gladius) by Dolphinfish (Coryphaena hippurus): New Ecological Insights into Both Species in the Tyrrhenian Sea

Fishes
Knowledge of post-larval swordfish (Xiphias gladius) ecology in the world’s oceans is incomplete as they are rarely found in ichthyoplankton samplings or commercial catches and individuals are difficult to observe in the marine ecosystem.

Management Implications of Mesopelagic Forage Fisheries for Bigeye Tuna Stocks

Fisheries Management and Ecology, EarlyView.
ABSTRACT Many large marine predators forage on mesopelagic fish stocks, including commercially valuable tunas. The mesopelagic is under increasing interest for commercial exploitation, given its large biomass with potential to supply fishmeal for aquaculture feed or fish oil.

Estimated Dietary Intake of Trace Metals from Swordfish Consumption: A Human Health Problem

Toxics, 2018
Trace element (Hg, Pb, Cd, Zn, Cu, Ni, and Cr) occurrence was determined in the muscle tissue of swordfish collected in the Mediterranean Sea to assess whether the intakes complied with the recommended levels for essential metals and permissible levels ...
