Kizhakudan Research Centre of CMFRI, Chennai 3f With the decline in many commercial fisheries worldwide and an ever increasing demand for seafood protein, there is a growing need for augmenting the production of high-protein, high-value resources like lobsters. Aquaculture remains the ideal measure to augment production and ensure conseNation, and even enhancement. of natural stocks. Aquaculture provides a two-pronged solution towards increasing the fish production through ., farming of hatchery-produced seed of commercially important finfishes and shellfishes , enhancing natural stocks by sea ranching hatchery-produced seed of commercially important finfishes and shellfishes Lobsters are among the most priced seafood delicacies enjoying a special demand in international markets. As against a world average annual productio'n of2.1 lakh tonnes, India's average annual lobster production is about 2000 tonnes. With the distinction of being perhaps, the only seafood resource in India's trade economy, which remains relatively low down the ladder in terms of quantity of production but brings in maximum foreign exchange, lobsters have been the subject of study for more than two decades now. -

DOCTORAL THESIS a Physio-Ecological Study of Ephyrae
DOCTORAL THESIS A Physio-ecological Study of Ephyrae of the Common Jellyfish Aurelia aurita s.l. (Cnidaria: Scyphozoa), with Special Reference to their Survival Capability under Starvation Zhilu Fu Graduate School of Biosphere Science Hiroshima University September 2014 DOCTORAL THESIS A Physio-ecological Study of Ephyrae of the Common Jellyfish Aurelia aurita s.l. (Cnidaria: Scyphozoa), with Special Reference to their Survival Capability under Starvation Zhilu Fu Department of environmental Dynamics and Management Graduate School of Biosphere Science Hiroshima University September 2014 Abstract The moon jellyfish Aurelia aurita s.l. is the most common scyphozoan jellyfish in the coastal waters around the world, and the mass occurrences of this species have been reported from various regions. In recent decades, A. aurita blooms have become increasingly prominent in East Asian seas, causing serious problems to human sectors such as fisheries and coastal power plant operations. Therefore, it is important to identify causes for the enhancement of A. aurita populations to forecast likely outbreaks prior to the season of medusa blooms. In the population dynamics of scyphozoan jellyfish, the following two factors are important to determine the size of adult (medusa) population: (1) the abundance of benthic polyps, which reproduce asexually and undergo seasonal strobilation to release planktonic ephyrae, and (2) the mortality of ephyrae before recruitment to the medusa stage. Although much knowledge has been accumulated about physio-ecology of the polyp stage by previous studies, only few studies have been conducted for the ephyra stage. The success for survival through larval stage is basically affected by two factors, viz. food availability and predation. -
Multiple Measures of Thermal Performance of Early Stage Eastern Rock Lobster in a Fast-Warming Ocean Region

While a single performance measure may give some insight, it may not be enough to ac - curately predict outcomes. Here, we used multiple measures of performance to explore potential mech- anisms behind species range shifts. We examined the thermal pattern for multiple measures of performance, including measures of aerobic metabolism and multi- ple as pects of escape speed, using the final larval stage (puerulus) of eastern rock lobster Sagmariasus verreauxi as a model species. We found that aerobic scope and escape speed had different thermal per- Single thermal performance measures for eastern rock lob- formances and optimal temperatures.

Does Climate Change Bolster the Case for Fishery Reform in Asia? Christopher Costello∗
Does Climate Change Bolster the Case for Fishery Reform in Asia? Christopher Costello∗ I examine the estimated economic, ecological, and food security effects of future fishery management reform in Asia. Without climate change, most Asian fisheries stand to gain substantially from reforms. Optimizing fishery management could increase catch by 24% and profit by 34% over business- as-usual management. These benefits arise from fishing some stocks more conservatively and others more aggressively. Although climate change is expected to reduce carrying capacity in 55% of Asian fisheries, I find that under climate change large benefits from fishery management reform are maintained, though these benefits are heterogeneous. The case for reform remains strong for both catch and profit, though these numbers are slightly lower than in the no-climate change case. These results suggest that, to maximize economic output and food security, Asian fisheries will benefit substantially from the transition to catch shares or other economically rational fishery management institutions, despite the looming effects of climate change. Keywords: Asia, climate change, fisheries, rights-based management JEL codes: Q22, Q28 I. Introduction Global fisheries have diverged sharply over recent decades. High governance, wealthy economies have largely adopted output controls or various forms of catch shares, which has helped fisheries in these economies overcome inefficiencies arising from overfishing (Worm et al. 2009) and capital stuffing (Homans and Wilen 1997), and allowed them to turn the corner toward sustainability (Costello, Gaines, and Lynham 2008) and profitability (Costello et al. 2016). But the world’s largest fishing region, Asia, has instead largely pursued open access and input controls, achieving less long-run fishery management success (World Bank 2017). -

Large Spiny Lobsters Reduce the Catchability of Small Conspecifics
Vol. 666: 99–113, 2021 MARINE ECOLOGY PROGRESS SERIES Published May 20 https://doi.org/10.3354/meps13695 Mar Ecol Prog Ser OPEN ACCESS Size matters: large spiny lobsters reduce the catchability of small conspecifics Emma-Jade Tuffley1,2,3,*, Simon de Lestang2, Jason How2, Tim Langlois1,3 1School of Biological Sciences, The University of Western Australia, 35 Stirling Highway, Crawley, WA 6009, Australia 2Aquatic Science and Assessment, Department of Primary Industries and Regional Development, 39 Northside Drive, Hillarys, WA 6025, Australia 3The UWA Oceans Institute, Indian Ocean Marine Research Centre, Cnr. of Fairway and Service Road 4, Crawley, WA 6009, Australia ABSTRACT: Indices of lobster abundance and population demography are often derived from pot catch rate data and rely upon constant catchability. However, there is evidence in clawed lobsters, and some spiny lobsters, that catchability is affected by conspecifics present in pots, and that this effect is sex- and size-dependent. For the first time, this study investigated this effect in Panulirus cyg nus, an economically important spiny lobster species endemic to Western Australia. Three studies: (1) aquaria trials, (2) pot seeding experiments, and (3) field surveys, were used to investi- gate how the presence of large male and female conspecifics influence catchability in smaller, immature P. cygnus. Large P. cygnus generally reduced the catchability of small conspecifics; large males by 26−33% and large females by 14−27%. The effect of large females was complex and varied seasonally, dependent on the sex of the small lobster. Conspecific-related catchability should be a vital consideration when interpreting the results of pot-based surveys, especially if population demo graphy changes. -

Peatman, Assistant Professor, Fisheries and Allied Aquacultures Joseph C. Newton Associate professor, College of Veterinary Medicine Abstract Investigative studies were conducted on the relative effectiveness between carp pituitary extract (CPE), luteinizing hormone releasing hormone analog (LHRHa) injections and LHRHa implants for producing hybrid catfish embryos. Data from the past 15 years, which included, 25 on CPE, 20 on LHRHa injections, and 20 for LHRHa implants, respectively, were evaluated. LHRHa administered as an injection or implant produced more (P<0.001) fry/kg than CPE. Mean fry/kg female body weight (all females) produced was 948 for, CPE 2,483 LHRHa injections and 2,765 for LHRHa. There was not a significant difference in fry/kg between the two LHRHa treatments. The coefficient of variance indicated more consistent results for CPE (CV=37.5), and LHRHa implants (CV= 35.9) than LHRHA injections (CV= 49.9). The second study investigated the effectiveness of OVA-EAZE a Luteinizing Hormone Releasing Hormone analog (LHRHa). This study investigated des-Gly10,[D-Ala6] LHRH Ethyl amide (LHRHa) administered in two doses of 20 µg per kilogram of female channel catfish body weight as a priming dose, followed 12 hours later by a resolving injection of 100 µg per kilogram of body weight, to determine its effectiveness in inducing ovulation in channel catfish (Ictalurus punctatus). -
