Ikan sidat termasuk ikan yang memiliki kandungan gizi yang tinggi seperti vitamin A, vitamin B, DHA(Docosahexaenoic acid), EPA(Eicosapentaeonic acid), dan protein albumin. Albumin memiliki peranan penting sebagai sarana pada proses transportasi dalam darah, pembentukan jaringan tubuh yang baru pada masa pertumbuhan, senyawa proteksi hati dan juga bermanfaat dalam proses penyembuhan luka pada pasien pasca operasi. Penelitian ini bertujuan untuk mengetahui perbandingan kadar albumin ikan sidat Anguilla marmorata dan Anguilla bicolor pada fase glass eel, elver, yellow eel dan silver eel asal Sungai Palu dan Danau Poso. Sampel diambil menggunakan metode purposive sampling berdasarkan pada jenis, berat, ukuran, dan lokasi pengambilan. Pengujian kadar albumin ditentukan dengan menggunakan metode Bromocresol green dengan alat fotometer dan hasil penelitian menunjukkan bahwa kadar albumin tertinggi terdapat pada fase silver eel, yakni sebanyak 1,62 gram / 100 gram pada Anguilla marmorata asal Danau Poso dan kadar paling rendah terdapat pada fase elver sebanyak 0,24 gram / 100 gram pada Anguilla bicolor asal Danau Poso. Hal ini menunjukkan bahwa spesies Anguilla marmorata memiliki kadar albumin yang lebih tingi dari Anguilla bicolor.

Abstract Stocking of young eel is widely practised, as a measure, to meet the management target of the EU eel recovery plan. The target of the recovery plan is to increase the escapement to 40% silver eel biomass, relative to pristine conditions. The scientific information to predict the outcome in silver eel biomass from stocking is limited and may depend on whether translocation of wild glass eel or yellow eel is used, or if the stocked eels used are yellow eel from aquaculture. We evaluated the yield from stocking two different sizes, 3 and 9 g eels from aquaculture. A professional fishery recaptured 12.7% of the 3 g and 9.4% of the 9 g eels, originally stocked. Growth rate and mortality rate were different for the two stocked sizes, favouring the small eels. Brutto yield per recruit (YPR) was 13 and 9.2 g and netto YPR was 9.8 and 0.31 g for 3 and 9 g eel, respectively. We conclude that there seems to be no advantage in using larger 9 g eels compared with small 3 g eels for stocking.

<em>Abstract.—</em>The two main species of freshwater eels in New Zealand, the shortfin <em>Anguilla australis </em>and the endemic longfinned eel <em>A. dieffenbachii</em>, are extensively commercially exploited and also support important customary fisheries. Since there are no commercial glass eel fisheries in New Zealand, other indices must be used to indicate changes in recruitment over time. While there is some anecdotal evidence of reductions in glass eel recruitment, there is evidence of poorly represented cohorts of longfins within some populations, and modeling of these data indicate a substantial reduction in recruitment over the past two decades. Growth of both species is typically slow at 2–3 cm per year, meaning that both species are susceptible to commercial capture for many years until spawning escapement. Extensive commercial fishing has resulted in more substantial changes in length-frequency distributions of longfins than in shortfins; likewise, regional reductions in catch per unit effort are more significant for longfins. Theoretical models of silver eel escapement indicate that longfin females are especially susceptible to overexploitation. Shortfins would have been more impacted than longfins by loss of wetlands, but the impact of hydro stations on upstream access for juvenile eels and downstream access for silver eels would have been more severe for longfins. Overall, there is no clear evidence that the status of shortfin eel stocks has been seriously compromised by the extensive commercial eel fishery, but there is increasing evidence that longfins are unable to sustain present levels of exploitation.

<em>Abstract.—</em>Long-term changes in eel stock status are examined in two catchments in England. The River Severn supports the UK’s major glass eel fishery. The Rivers Piddle and Frome and Poole Harbour form a linked river/tidal lagoon system supporting yellow and silver eel fisheries. Eel population density and structure in lower Severn tributaries appear unchanged since the early 1980s, as does eel distribution in the upper catchment. It is concluded that, despite a decline in glass eel numbers and increased fishing pressure in the 1990s, recruitment continues to be sufficient to fill local carrying capacity. In contrast, in the Piddle and Frome, population density has declined sharply since the 1970s, and there has been a major change in sex ratios from male to female domination. Although currently high, female silver eel escapement is likely to decline sharply over the next few years from the Piddle and possibly the Frome. It is postulated that the productive tidal lagoon acts as a sink for declining glass eel recruits so that fewer elvers and yellow eels are entering the rivers. Fishing pressure on harbor stocks is unquantified but potentially high. Management options and priorities for the two catchments are discussed.
